Some plausibly necessary a posteriori theoretical claims include 'water is H2O', 'gold is the element with atomic number 79', and 'cats are animals'. In this paper I challenge the necessity of the third claim. I argue that there are possible worlds in which cats exist, but are not animals. Under any of the species concepts currently accepted in biology, organisms do not belong essentially to their species. This is equally true of their ancestors. In phylogenetic systematics, monophyletic clades such as the animal kingdom are composed of an ancestral stem species and all of its descendants. If the stem species had not existed, neither would the clade. Thus it could have been the case that all the organisms which actually belong to the animal kingdom might have existed yet not have been animals. [ABSTRACT FROM AUTHOR]

Simple Summary: To date, there are very few studies of the bony nasal cavity of the domestic cat and even fewer of big felids. A detailed and exhaustive anatomical study of this cavity in the domestic cat is presented in this paper through dissections, trepanations and anatomical sections. This work has allowed to delve deeper into the anatomy of the bony nasal cavity. This study deepens the knowledge of this region through diagnostic imaging techniques, such as computed tomography, three-dimensional reconstruction in maximum-intensity projection and volume rendering, that allow for the spatial visualization of this cavity. These reconstructed images represent an improvement in the anatomical study of the cavity and will help veterinary clinicians in the diagnosis of nasal pathologies. Obtaining molds by three-dimensional printing allows for acquiring models very close to reality that capture these structures in detail. These techniques, which in human medicine have already led to many clinical and therapeutic improvements, are a very useful tool in veterinary medicine that will lead to advances and improvements in the diagnosis and treatment of nasal pathologies, improving the survival of many threatened species. This study aims to develop three-dimensional printing models of the bony nasal cavity and paranasal sinuses of big and domestic cats using reconstructed computed tomographic images. This work included an exhaustive study of the osseous nasal anatomy of the domestic cat carried out through dissections, bone trepanations and sectional anatomy. With the use of OsiriX viewer, the DICOM images were postprocessed to obtaining maximum-intensity projection and volume-rendering reconstructions, which allowed for the visualization of the nasal cavity structures and the paranasal sinuses, providing an improvement in the future anatomical studies and diagnosis of pathologies. DICOM images were also processed with AMIRA software to obtain three-dimensional images using semiautomatic segmentation application. These images were then exported using 3D Slicer software for three-dimensional printing. Molds were printed with the Stratasys 3D printer. In human medicine, three-dimensional printing is already of great importance in the clinical field; however, it has not yet been implemented in veterinary medicine and is a technique that will, in the future, in addition to facilitating the anatomical study and diagnosis of diseases, allow for the development of implants that will improve the treatment of pathologies and the survival of big felids.

Sporotrichosis is a mycosis with zoonotic potential caused by species of Sporothrix. Once thought rare in northeastern Brazil, the disease has recently been spreading, leading to an emergency health issue. In this paper, we describe an outbreak of feline sporotrichosis in the Seventh Health District of Maceió-AL. We collected samples from 23 domiciled and non-domiciled felines without regard for age, breed, sex, and neutering state. Skin samples were analyzed cytologically under a light microscope and seeded onto Sabouraud dextrose agar at 25 °C for from 15 to 30 days. Fifteen of the twenty-three cats with suspected skin lesions were positive for Sporothrix spp. on either cytological or microbiological evaluation. Most of the infected cats were male, young adults, non-neutered, with free access to external areas, and living in environments with poor sanitation, a high population density, and an accumulation of garbage and organic matter. Three owners were bitten or scratched by infected cats and subsequently developed suspicious cutaneous lesions suggestive of sporotrichosis. The epidemiological features of feline sporotrichosis in the outbreaks of Maceió seemed to share similarities with the data obtained from outbreaks in current hyperendemic areas. Identifying geographical sites of infection and providing compulsory notification of the disease is essential for avoiding an epidemic in Alagoas. [ABSTRACT FROM AUTHOR]

Simple Summary: In spite of significant reductions in the numbers of animals entering shelters and being killed there over the last decades, the beliefs that companion animals must be under the direct control of a human guardian, and that capturing and often killing animals is morally justifiable and even necessary, continue to guide animal sheltering practices in the United States. Looking at the historical origins of animal control and sheltering in the US reveals a high level of consistency in ideologies and practices across almost 150 years. In this commentary, two scholars on animal sheltering in the US examine the historical legacies of animal control and sheltering in the US to show how they are problematic and dysfunctional and need to be abandoned to improve the lives of companion animals and the human communities of which they are a part. This paper examines the legacies of the emergence of the animal control and sheltering industry in the United States and their impact on contemporary public animal shelters. While decades of gradual reform have helped substantially reduce the number of animals entering shelters and being killed there, contemporary animal sheltering largely continues to follow the path set when animal sheltering developed in the late 1800s and early 1900s. Three key interrelated legacies of the pound model of early animal control and sheltering enduringly shape sheltering today: (1) the institutional culture of animal shelters grounded in the logics of caging and killing; (2) the lack of visibility and transparency, especially within government shelters; and (3) the economic logics of the pound model, including the disparities in sheltering resources across communities. Examining the origins of animal control and sheltering and identifying the specific legacies of this pound model within contemporary government-funded shelters improves understanding of why such shelters in the US have developed with a particular set of practices and ideologies, and thus provides an important footing for envisioning and enacting radical changes in animal sheltering.

Background: Sparganosis is a rare zoonotic disease caused by plerocercoid larvae of the genera Spirometra or Sparganum (Cestoda: Diphyllobothriidae). The larvae of Spirometra generally do not undergo asexual reproduction, whereas those of Sparganum can induce proliferative lesions in infected tissues. This paper presents an unusual case of proliferative sparganosis due to infection with Spirometra mansoni in a cat, normally considered a definitive host of the species. Case presentation: A 9-year-old male domestic cat was presented with a mass on the right side of the face that underwent progressive enlargement for 1 month. The morphological and histopathological examinations revealed multiple asexual proliferative cestode larvae in the lesions, suggestive of proliferative sparganosis. Next-generation sequencing analysis of formalin-fixed and paraffin-embedded specimens of surgically excised tissue indicated that the worm was Spirometra mansoni. Conclusion: Although S. mansoni a common tapeworm species found in the small intestine of domestic cats and dogs in Japan, proliferative sparganosis is extremely rare. This is the first confirmed case of proliferative sparganosis due to infection with S. mansoni in cat. [ABSTRACT FROM AUTHOR]

The COVID-19 pandemic represented a huge obstacle for public health and demonstrated weaknesses in surveillance and health promotion systems around the world. Its etiological agent, SARS-CoV-2, of zoonotic origin, has been the target of several studies related to the control and prevention of outbreaks and epidemics of COVID-19 not only for humans but also for animals. Domestic animals, such as dogs and cats, have extensive contact with humans and can acquire the infection both naturally and directly from humans. The objective of this article was to summarize the seroprevalence findings of SARS-CoV-2 in dogs and cats and correlate them with the strength of infection risk between each of them. This is a systematic review and meta-analysis following the recommendations of PRISMA 2020. The search and selection of papers was carried out using in vivo experimental works with animals using the descriptors (MeSH/DeCS) "Animal", "Public Health", "SARS-CoV-2" and "Pandemic" (together with AND) in English, Portuguese or Spanish for Science Direct, PUBMED, LILACS and SciELO databases. The ARRIVE checklist was used for methodological evaluation and the Comprehensive Meta-Analysis v2.2 software with the Difference Risk (RD) test to evaluate statistical inferences (with subgroups by continent). Cats showed greater susceptibility to SARS-CoV-2 compared to dogs both in a joint analysis of studies (RD = 0.017; 95% CI = 0.008–0.025; p < 0.0001) and in the American subgroup (RD = 0.053; 95% CI = 0.032–0.073; p < 0.0001), unlike the lack of significant difference on the European continent (RD = 0.009; 95% CI = −0.001–0.018; p = 0.066). Therefore, it was observed that cats have a greater interest in health surveillance due to the set of biological and ecological aspects of these animals, but also that there are a set of factors that can influence the spread and possible spillover events of the virus thanks to the anthropozoonotic context.

"The Cat: it possesses beauty without vanity, strength without insolence, courage without ferocity, all the virtues of man without his vices" (Lord Byron). This paper is a photographic summary of trips to three cities that we consider among the most representative of the harmonious relationship between humans and cats: Istanbul, Kotor, and Saint Petersburg. The photos show some of the beauty of these cities: architecture, avenues, museums, squares, parks, the natural beauty of the surroundings, and, of course, its community's cats.

Immunosuppressive drugs are the mainstay of treatment for many feline and canine autoimmune skin diseases, either as monotherapy or in combination with other drugs. Treatment with these drugs is often lifelong and may have long‐term consequences on the affected animal's overall quality‐of‐life. Clinicians need to understand the pharmacology of immunosuppressants in planning and executing the treatment regimen for the best possible clinical outcome, as well as reducing the risk of adverse effects. This review paper will focus on the mechanism of action, pharmacokinetics and pharmacodynamics, clinical uses and adverse effects of immunosuppressive drugs used to treat autoimmune dermatoses in cats and dogs. These include glucocorticoids, ciclosporin A, azathioprine, chlorambucil, mycophenolate mofetil, oclacitinib and Bruton's tyrosine kinase inhibitors. [ABSTRACT FROM AUTHOR]

The field of animal affective computing is rapidly emerging, and analysis of facial expressions is a crucial aspect. One of the most significant challenges that researchers in the field currently face is the scarcity of high-quality, comprehensive datasets that allow the development of models for facial expressions analysis. One of the possible approaches is the utilisation of facial landmarks, which has been shown for humans and animals. In this paper we present a novel dataset of cat facial images annotated with bounding boxes and 48 facial landmarks grounded in cat facial anatomy. We also introduce a landmark detection convolution neural network-based model which uses a magnifying ensemble method. Our model shows excellent performance on cat faces and is generalizable to human and other animals facial landmark detection. [ABSTRACT FROM AUTHOR]

Determination of the urinary protein-to-creatinine ratio (UPC) is an important tool in the quantification of proteinuria in animals. However, the result may be affected by the different methods of determining the urinary protein concentration. The aim of this study was to compare the turbidimetric method using benzethonium chloride and the colorimetric method using pyrogallol red in the measurement of the urinary protein concentration in dogs, cats, guinea pigs and horses. A total of 464, 192, 216 and 119 urine samples from dogs, cats, guinea pigs and horses were examined in the study, respectively. The group consisted of animals of both sexes and different ages, and, in the dogs and cats, it included both healthy animals and those with various health problems. In the group of horses and guinea pigs, only clinically healthy animals were included. A total of 347, 185, 103 and 100 samples from the dogs, cats, guinea pigs and horses were used in the statistical analysis; the other values were excluded as they were below the detection limit. According to the Passing-Bablok analysis, there was a significant constant and proportional difference in the horses. In the dogs, cats and guinea pigs, there was a significant constant difference, but no proportional difference. The Bland-Altman method showed significant bias between the two methods in the horses and cats, but not in the dogs and guinea pigs. In the dogs and cats, the agreement between the two methods was tested and expressed as Cohen’s kappa (κ). In the cats, it was almost perfect for the proteinuric samples (κ = 0.823 3) and significant for the non-proteinuric samples (κ = 0.804 9). In the dogs, the agreement was significant for the non-proteinuric samples (κ = 0.621 5) and only moderate for the proteinuric samples (κ = 0.527 5). The influence of the method used to determine the urinary protein concentration should be taken into account when evaluating the UPC. Repeated examinations in one patient should be performed with the same method. [ABSTRACT FROM AUTHOR]

Ice clouds can strongly affect the radiation budget through the reflection (absorption) of solar shortwave (longwave) radiation in the Earth-atmosphere system. Unlike water clouds, ice clouds present a longer lifetime in the upper troposphere. Therefore, the vertical patterns of diurnal variation of ice clouds are of very importance to understand climate change in the globe. The present paper investigates the diurnal variation of ice cloud frequency (ICF) from March 2015 to October 2017 over the global scale (51 ° S and 51 ° N) by CATS (Cloud-Aerosol Transport System) LiDAR onboard the International Space Station (ISS) and CALIPSO (Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations) LiDAR measurements. Our results suggest that: (1) ICF derived from the CATS and CALIPSO LiDAR presents the similar geographical variations. (2) The vertical distribution of ICF in land area over the North Hemisphere (NH) is found larger than in the South Hemisphere (SH) likely due to the more dust aerosols as ice nuclei to influence ice cloud formation over the NH. (3) ICF at nighttime (00:00–06:00 and 18:00–23:00) exhibits higher value than daytime (06:00–18:00), especially in high altitude (more than 12 km) ice clouds in the tropics. (4) The number of ice cloud samples is higher in spring and winter compared to summer and autumn, and the highest amount of ice cloud samples in spring(winter) occurs during nighttime(daytime) for most hours. These findings provide significant insights that may help improving the ice cloud's representation in climate models. • The present paper investigates the diurnal variation of ice cloud frequency (ICF) from March 2015 to October 2017 over the global scale (51 ° S and 51 ° N) by CATS and CALIPSO LiDAR measurements. • ICF derived from the CATS and CALIPSO LiDAR presents the similar results.

A recent article in the Veterinary Ireland Journal discusses the availability of a new treatment for feline infectious peritonitis (FIP) that was previously not legally importable in the Republic of Ireland. The article explains that FIP is a disease caused by feline coronavirus and is most commonly seen in young cats. The symptoms of FIP can vary but often include fever, loss of appetite, weight loss, and lethargy. The article also mentions that there is no single, fully accurate diagnostic test for FIP, making it challenging to confirm a diagnosis. However, there are now anti-viral treatments available for FIP, such as remdesivir and GS-441524, which have shown a good success rate. Previously, these medications could not be imported into Ireland, leading some cat owners to obtain them illegally online. However, new EU veterinary medicines regulations now allow veterinarians in Ireland to apply for a special license to import these medications for individual cats with a diagnosis of FIP. The article concludes by mentioning an outbreak of a novel feline coronavirus in Cyprus, which has caused an increase in FIP cases on the island. Veterinarians in Cyprus have been treating affected cats with the new antiviral drugs successfully. Helpful resources for more information on FIP are provided at the end of the article.

In the wake of recent medical developments in small animal practice, curing animals of their illnesses and restoring their health can be realized better than ever before. However, the growing medical possibilities are also leading to an increase in demand for better care for patients suffering from terminal illnesses. Consequently, the field of animal hospice and palliative care has become increasingly available, enabling veterinarians to optimize the quality of life of patients, such as dogs and cats, who no longer have a prospect of full recovery. Using qualitative, semi-structured interviews with 20 small animal veterinarians involved in hospice and palliative care, we investigated the factors that motivate veterinarians to become involved in hospice and palliative care and explored the importance of relationships, communication, time and infrastructure in this area. Findings show that personal experiences with their own pets or during training or work life motivated veterinarians to provide this service. Although veterinarians highlighted the importance of empathetic-driven relationships, they were aware that keeping an emotional distance from the patient and caregiver is significant to provide successful care. Further, veterinarians emphasized their high investment of time that resulted primarily from the increased frequency and provided opportunities to communicate with caregivers. The overall conclusion is that having time for patients and the patients' caregivers is one of the most important aspects of work in this field. However, as it will be also shown, veterinarians must consider aspects of self-care management by reflecting on their own time and energy resources while caring for animals and their caregivers.

Objectives: To adapt the Charlotte Attitudes Toward Sleep (CATS) scale, the only self-assessment instrument measuring non-dysfunctional attitudes toward sleep, into Portuguese and to study its psychometric properties in a Portuguese sample. Method: A sample of 1858 participants, recruited through non-probabilistic methods, was randomly split in two subsamples; one was used to develop the CATS model, the other for testing model invariance. We used structural equation models to assess factorial validity, measurement invariance, and relationships with other variables (e.g., the Karolinska Sleep Questionnaire) through confirmatory factorial analysis and causal models using a robust maximum likelihood method with Satorra-Bentler correction. Results: The CATS factorial model showed excellent evidence of factorial validity (robust CFI = 0.987, TLI = 0.979, SRMR = 0.026, RMSEA = 0.043), good reliability indicators (α and ώ1 > 0.75), and strict invariance of measurement (|∆CFI|< 0.01). CATS factors were weak-to-moderate predictors of sleep behaviors (β < 0.4). The scale showed evidence of divergent validity with the Karolinska Sleep Questionnaire. Some items had significant sensitivity problems and/or did not have adequate factorial weights and had to be dropped from the model. Conclusions: The CATS is a new and promising scale with solid evidence of validity in terms of internal structure, but with sensitivity issues at item level. Further work should be carried out at item level to increase sensitivity and predictive validity, and further research with other samples, such as clinical sleep medicine patients, should be conducted.

Using pheromone diffusers is part of the strategy to control stress-related behaviors in cats (Felis catus). The goal of the study was to compare the efficacy of a novel long-acting, unpowered gel-based diffuser containing a facial pheromone analog (Zenifel® gel diffuser, Virbac) with a similar electrically powered feline pheromone diffuser that already has proven efficacy, on situational stress in cats, at home. The study involved 90 owners of cats presenting undesirable behaviors receiving one diffuser or the other: 46 received one gel diffuser and 44 received one plug-in device and a refill, for the 2-month study duration. The presence of the various undesirable behaviors was checked regularly and a general score was given to rate their presence. The most reported behaviors were related to hypervigilance, seeking the owner’s attention, hiding, excessive vocalization, inactivity, and excessive scratching. All six behaviors significantly improved over time with Zenifel® while only four improved with the reference product (no improvement for excessive meowing and inactivity). The general score significantly improved as of day 7 in both groups, with no difference between groups. More owners said they would use the product throughout the year with Zenifel® than with the reference product (80% vs. 42%, p  <  0.05). Therefore, both diffusers can be used to help control undesirable behaviors of cats at home but Zenifel® is more convenient to use throughout the year. [ABSTRACT FROM AUTHOR]

Influenza A virus (IAV) can cause high morbidity and mortality in domestic and wild avian species and it is able to infect mammals as well. IAV in cats is sporadic and self-limiting but the recent findings of high pathogenicity avian influenza virus (HPAIV) with genetic signatures ofmammalian adaptation, in domestic cats, has raised new concerns about the potential role of cats in the virus ecology. The present study aimed to investigate the circulation of IAV in companion animals' shelters in North-eastern Italy. All samples were collected from feral cats living in feline colonies that were hosted in the companion animals' shelters for the requisite period to administer the veterinary treatments. Between 2021 and 2022, 389 oropharyngeal swabs and 279 sera were collected. All swabs tested negative for IAV and the only one ELISA positive serum sample resulted H5 positive by HI test with a titer of 1:80. Despite the sporadic occurrence of influenza in cats, continuousmonitoring is crucial due to the evolving zoonotic nature of the virus. [ABSTRACT FROM AUTHOR]

A 12‐year‐old male domestic cat with multiple subcutaneous mast cell tumours (MCTs) presented with a 2‐week history of pruritus and raw/bleeding skin from self‐trauma at Kagoshima University Veterinary Teaching Hospital. Polymerase chain reaction (PCR) and histopathological analyses revealed intertumoral heterogeneity among tumour locations based on the mutation status of KIT. In addition, the expression pattern of KIT was characterized. After failed treatment with vinblastine (2.0–2.2 mg/m2, intravenous administration, two doses in total) or nimustine (25 mg/m2, intravenous administration, two doses in total), toceranib (2.2–2.6 mg/kg, orally administered, every other day) was administered to treat recurrent MCTs harbouring the KIT exon eight internal tandem duplication mutation, achieving a complete response. However, toceranib resistance developed 2 months after treatment initiation. Subsequent PCR analysis was conducted to identify the mutational status of KIT in each MCT and to detect the presence of secondary mutations associated with the acquisition of toceranib resistance. Secondary KIT mutations (c.998G>C and c.2383G>C), which were not initially detected in tumour cells at diagnosis, were identified after the development of resistance to toceranib. This indicates that the tumour cells in feline MCTs in the same case have diverse characteristics. Our findings encourage further investigation into the development of therapeutic strategies for feline MCTs, particularly focusing on the heterogeneous nature of KIT/KIT and overcoming acquired resistance to toceranib.

Simple Summary: This study investigates the reasons behind the relinquishment of companion animals, specifically cats and dogs, to an open-admission shelter in the US. We analyzed 2836 randomly selected owner relinquishment records over a six-year period (2018–2023) using content analysis, a systematic method for categorizing qualitative data. The most common reasons identified for relinquishment included behavioral issues (28%), housing/moving (18%), and the inability to care for the animals (16%). Aggression, social conflict, and soiling were the most common behavioral-issue reasons reported. However, differences were observed in the pattern of relinquishment reasons based on statistical analyses of species, type of relinquishment, and year. The study found no significant increase in relinquishments due to financial or housing pressures during the peri-pandemic period, but there was an increase in relinquishments due to owners being otherwise unable to care for their pets in 2022 and 2023. This research provides valuable insights for animal welfare organizations and policymakers to develop strategies to better understand animal relinquishment and improve the welfare of both animals and their owners. The relinquishment of companion animals to shelters presents significant challenges for animal welfare organizations and has substantial implications for the well-being of both the animals and their owners. This study aims to investigate the reasons for voluntarily relinquishing animals to shelters, to examine species-specific differences (cats and dogs), to compare initial relinquishments to returns (re-relinquishments or readmissions), and to identify potential changes over a 6-year period framing the onset of the COVID-19 pandemic. A retrospective analysis of owner relinquishment records from an open admission shelter in the US was conducted using content analysis, a novel approach in this area of research. A total of 13 relinquishment reason categories were identified, as well as 9 separate categories for specific behavioral issues. Among 2836 randomly selected records, the most frequent reasons cited were Behavior Issues (28%), Housing/Moving (18%), Unable to Care (16%), Too Many Pets (10%), Financial (6%), and Owner Allergies (5%). The most common behavioral reasons reported were Aggression (32% of behavioral surrenders), Social Conflict (28%), and Soiling (13%). However, differences were observed in the pattern of relinquishment reasons based on statistical analyses of species, type of relinquishment, and year. Regarding temporal trends, Housing/Moving and Financial reasons were not found to have changed significantly since the pandemic, but the relative frequency of the category Unable to Care increased significantly in 2022 and 2023. Collectively, these findings partially replicate those from research spanning the past several decades in this area that has employed less systematic methodology and can further be used to help identify and understand the primary drivers of owner relinquishments.

Simple Summary: The Formosan pangolin (Manis pentadactyla pentadactyla) is a rare and enigmatic species endemic to Taiwan. Due to its declining population and elusive behavior, little is known about its reproduction. This study created a genomic database of the male pangolin's reproductive tract, identifying key genes and pathways in the testis and epididymis. Comparing testicular genes expression between pangolins and domestic cats, we suggested that the cat is not a suitable model for studying pangolin reproduction due to significant differences. These insights advance our understanding of male pangolin reproduction and may help in the development of future artificial reproductive techniques for pangolins. The Formosan pangolin (Manis pentadactyla pentadactyla) is an endemic animal of Taiwan. Due to their reduced population and behavior, very little is known about this enigmatic species. To unravel male pangolin reproduction, in the present study, we built a complete genomic database of the male Formosan pangolin reproductive tract and revealed highly expressing genes as well as critical signaling pathways and their associated biological processes in both the testis and the epididymis. Moreover, we evaluated the domestic cat (Felis catus) as a potential model species for male pangolin reproduction by comparing their testicular transcriptomes. We demonstrated a clear tissue-specific gene expression supporting the unique biological signature of each reproductive tissue and identified critical genes of the different reproductive organs. Pathway enrichment analysis revealed unique pathways in the testis as well as a clear epididymal transition. Furthermore, domestic cats, despite being the closest domestic species to pangolin, demonstrated their unfitness as a male reproduction model species as clear differences in spermatid differentiation and metabolism were observed. These results enable a better understanding of male pangolin reproduction characteristics and may inspire improvements in in Formosan pangolin conservation strategies. [ABSTRACT FROM AUTHOR]

Simple Summary: In cats, obesity and metabolic disorders are significant diseases; however, the relationship between a cat's metabolic health and gut microbiome remains unclear. This study investigated differences in gut microbiota among three groups of cats: those with normal body weight, metabolically healthy obese cats, and metabolically unhealthy obese cats. Microorganisms that metabolize carbohydrates, including Bifidobacteriaceae, were more abundant in obese cats. Conversely, Ruminococcaceae were more abundant in metabolically unhealthy obese cats. However, obesity, whether MHO or MUO, had only a minimal impact on fecal microbiota. Therefore, further studies are warranted to investigate whether gut microbiota could be a beneficial tool for the treatment or management of this condition. Obesity is a major public health concern in both humans and animals, leading to several metabolic complications. Recent human studies have classified obesity into two phenotypes, metabolically healthy (MHO) and metabolically unhealthy (MUO) obesity based on cardiovascular and metabolic risk factors. MHO cases lack these risk factors and are protected from metabolic complications of obesity, whereas MUO cases exhibit the opposite characteristics. Moreover, recent studies have highlighted the possible role of the gut microbiome in determining metabolic health of obese individuals. However, studies on the association between the gut microbiome and obesity and metabolic abnormalities in cats are limited. Therefore, we aimed to examine the association between metabolic health phenotypes and gut microbiota composition and diversity in obese cats. We investigated hormone and serum biochemistry parameters and composition of the gut microbiota in non-obese (NO), MHO, and MUO groups. The abundances of Bifidobacteriaceae, Coriobacteriaceae, and Veillonellaceae were significantly higher in the obese versus NO group, showing a positive correlation with body mass index. The abundance of Ruminococcaceae was significantly higher in the MUO versus NO group, showing a positive correlation with triglyceride and total cholesterol levels. However, obesity, whether MHO or MUO, had only a minimal impact on fecal microbiota. Therefore, further studies are warranted to investigate whether gut microbiota could be a beneficial tool for the treatment or management of this condition. [ABSTRACT FROM AUTHOR]

The Planetary Boundary Layer Height (PBLH) significantly impacts weather, climate, and air quality. Understanding the global diurnal variation of the PBLH is particularly challenging due to the necessity of extensive observations and suitable retrieval algorithms that can adapt to diverse thermodynamic and dynamic conditions. This study utilized data from the Cloud-Aerosol Transport System (CATS) to analyze the diurnal variation of PBLH in both continental and marine regions. By leveraging CATS data and a modified version of the Different Thermo-Dynamics Stability (DTDS) algorithm, along with machine learning denoising, the study determined the diurnal variation of the PBLH in continental mid-latitude and marine regions. The CATS DTDS-PBLH closely matches ground-based lidar and radiosonde measurements at the continental sites, with correlation coefficients above 0.6 and well-aligned diurnal variability, although slightly overestimated at nighttime. In contrast, PBLH at the marine site was consistently overestimated due to the viewing geometry of CATS and complex cloud structures. The study emphasizes the importance of integrating meteorological data with lidar signals for accurate and robust PBLH estimations, which are essential for effective boundary layer assessment from satellite observations.

Introduction: Cancer is a leading cause of death in cats, and the rate of such disease has been increasing recently. Nonetheless, feline oncology represents an important area of study not only for the health and wellbeing of cats but also for human health since various types of cancer in cats share similarities to those found in humans. Therefore, epidemiological studies on feline oncology may suggest environmental and genetic factors contributing to cancer in cats, which can eventually be translated to improve human cancer care. Method: To provide an initial understanding of the epidemiology of feline neoplasms, a descriptive study was undertaken using a dataset documenting cases of feline cancer gathered fromthe Liguria region (northwest Italy) spanning from 2002 to 2022. The database includes tumor location, morphological codes of the International Classification of Diseases for Oncology, 3rd Edition (ICD-O-3), feline's breed, sex, neuter status, date of birth, date of diagnosis, national territorial unit code of the town of the owner's residence, and an alphanumeric string uniquely identifying the owner's surname. Results and discussion: The dataset involves a population of 4,399 cats, including 3,195 females (1,425 neutered) and 1,204 males (750 neutered). Our results indicate that mammary gland tumors are the most represented tumors in the female population, while soft tissue and skin cancers appear to have a higher abundance in the male population during the periods investigated (2002-2022). Moreover, Poisson regression analysis showed that not neutered female cats have a significantly increased risk of developing mammary gland tumors compared to the neutered female population [proportional morbidity ratio (PMR) neutered vs. not neutered = 0.58, 95% CI: 0.47-0.72]; meanwhile, for both sexes, for soft tissue and skin tumors, being neutered appears to be a risk factor (PMR neutered vs. not neutered = 2.26, 95% CI: 1.86-2.73; PMR neutered vs. not neutered = 1.16, 95% CI: 0.89-1.51). Finally, the evaluation of the Ligurian municipalities pollution, based on wild boars data (i.e., biomonitors), which coexisted with cats, was correlated to cancer development for all the tumors investigated (in polluted areas, estimated PMRs ranged from 42.61 to 80.13, 95% CI: 29.94-105.11). Overall, the data presented here suggest the use of the feline population as a possible animal model for human health, i.e., sentinel. [ABSTRACT FROM AUTHOR]

Background: Osteoarthritis causes chronic pain, impaired joint function, decreased mobility and negatively impacts quality of life (QOL). Anti-nerve growth factor antibodies bedinvetmab for dogs and frunevetmab for cats are licensed for the alleviation of osteoarthritis pain but their QOL impact is unreported. Our aim was to determine if these therapeutics improve QOL using a validated health-related QOL measure that generates scores in four domains of QOL-energetic and enthusiastic (E/E), happy and content (H/C), active and comfortable (A/C) and calm and relaxed (C/R)-in the dog and three in the catvitality, comfort and emotional wellbeing (EWB). Summary scores for physical wellbeing (PWB) and emotional wellbeing (EWB) for dogs and PWB for cats are calculated from the domain scores. Methods: Animals received bedinvetmab (dogs) at 0.5-1 mg/kg or frunevetmab (cats) at 1-2.8 mg/kg by subcutaneous injection on days 0, 28 and 56 and owners completed QOL assessments within 48 hours of day 0 and on days 14, 28, 56, 63 and 70 using a study-specific app. Results: Assessments were completed by 75 dog and 56 cat owners. By day 14 there was a statistically significant improvement (p = 0.001) in PWB, EWB and all domains except C/R (p = 0.005) in dogs and in all domains and PWB in the cat. Subsequently there was a continued improvement in all domains and summary scores (p = 0.001) except for H/C in the dog and EWB in the cat, which were excluded from the statistical model. The overall improvement in all domain scores in the cat and E/E and A/C in the dog exceeded the previously reported minimum important difference scores for the QOL measure, indicating a clinically significant change. Conclusion: Treatment with bedinvetmab and frunevetmab produced a significant improvement in the QOL of dogs and cats. This latest evidence for the use of these OA pain medications could be helpful in the clinical management of osteoarthritis and post-marketing clinical trials. [ABSTRACT FROM AUTHOR]

Background: European wildcats (Felis silvestris) are widely distributed in Europe and a strictly protected species in Germany. Lately, anthropogenic protective efforts lead to increasing numbers of wildcats in southwestern Germany. Moreover, in recent years the numbers of domestic cats are increasing. Thus, the contact between domestic and wildcats may lead to the spread of zoonotic pathogens in both animal species. As data on vector-borne pathogens (VBPs) in wildcats from Germany are limited to date, the objective of this study was to investigate the presence and current distribution of VBPs in wildcats from southwestern Germany. Methods: Skin and spleen samples from 117 European wildcats, originating from a regional carcass-monitoring program in southwestern Germany, were examined by real-time and conventional polymerase chain reaction (PCR) for the presence of Anaplasma phagocytophilum, Neoehrlichia mikurensis, Rickettsia spp., Bartonella spp., and Piroplasmida. Results: In total, 6.8% (n = 8) of the wildcats were Rickettsia-positive, specified as R. helvetica. Three wildcats were positive for A. phagocytophilum (2.6%), one for Bartonella spp., namely B. taylorii (0.8%), and 84 for Cytauxzoon spp. (71.8%). Out of these 84 samples, 23 were further sequenced revealing very high identity levels (99.84–100%) to C. europaeus, which is considered to be pathogenic for domestic cats. All wildcats were negative for the presence of N. mikurensis DNA. Conclusions: European wildcats in southwestern Germany are hosting several VBPs. With the exception of Cytauxzoon spp., low prevalence rates of most examined pathogens suggest that wildcats are primarily incidental hosts for sylvatic pathogens associated with rodents, in contrast to domestic cats. However, the high prevalence of the cat-associated pathogen C. europaeus suggests that wildcats in southwestern Germany may serve as reservoirs for this pathogen. [ABSTRACT FROM AUTHOR]

Background: Cats are now recognized as competent hosts for Leishmania infantum and a blood source for sand fly vectors. Although canine leishmaniosis (CanL) is endemic in Mediterranean Basin countries, large-scale epidemiological studies are lacking for feline leishmaniosis (FeL). This study aimed to assess the prevalence of L. infantum infections, associated risk factors, clinical signs, and clinicopathological abnormalities in domestic cat populations from six Mediterranean Basin countries. Methods: From 2019 to 2022, blood and serum samples of cats (n = 2067) living in Italy (n = 300), Greece (n = 297), Portugal (n = 295), France (n = 231), Israel (n = 313), and Spain (n = 631) were collected along with animal data (i.e., age, sex, breed, housing conditions, and geographical origin), clinical signs, and laboratory blood test parameters. Cats were grouped according to their age as kittens (up to 1 year), young (older than 1 and younger than 7 years), mature (between 7 and 10 years), and senior (older than 10 years). Serum samples were tested for L. infantum by immunofluorescence antibody test (IFAT) and enzyme-linked immunosorbent assay (ELISA), and blood samples of seropositive cats were tested for L. infantum kinetoplast deoxyribonucleic acid (kDNA). Viral infection by feline immunodeficiency virus (FIV) and feline leukemia virus (FeLV) was molecularly addressed in all cats enrolled. Statistical analysis was performed to evaluate the association between the risk of L. infantum infection and independent variables, and among co-infection of L. infantum with FIV and/or FeLV, clinical signs, and clinicopathological abnormalities. Results: Overall, 17.3% (358/2067) of cats scored positive for L. infantum by serological tests. Specifically, 24.7% were from Portugal, 23.2% from Greece, 16.6% from Israel, 15% from Spain, 13.3% from France, and 12.6% from Italy. Leishmania infantum DNA was detected in 15 seropositive animals. Housing condition and FIV infection proved to be risk factors for FeL. Leishmania seropositivity was significantly associated with weight loss, lymphadenomegaly, gingivostomatitis, and oral ulcers, as well as with reduced albumin and albumin/globulin ratio, increased total globulins and total proteins, leukocytosis, and thrombocytosis. Conclusions: This study provides, for the first time, a large-scale epidemiological survey on FeL and its clinical presentation, revealing that L. infantum circulates among domestic cats, especially shelter/free-roaming and FIV-infected animals, living in CanL endemic countries of the Mediterranean Basin.

Simple Summary: Community cats, who are unowned and free-roaming, are common in cities worldwide. The issue of managing community cats is widely debated in scientific research and public media, including in China. To understand public opinion on this matter, we surveyed 5382 city residents in China to ask about their attitudes towards these cats and different management strategies. The study found that a large portion of people (more than 60%) were willing to live alongside community cats and opposed trapping and killing them, and they agreed or strongly agreed with the use of the TNR method and its variations. The study also found that men or those with lower education or incomes were more inclined to support trap-and-kill and doing nothing as management methods for community cats. In contrast, females or those with higher incomes and education levels had more positive attitudes towards the cats and were more inclined to oppose inaction and support the TNR method for managing the cat population. Based on these findings, we discussed the implementation of TNR with adoption programs in urban Chinse communities and the need for educational campaigns to promote humane and effective cat management strategies. By understanding public attitudes, policy makers, educators, and urban residents can develop better solutions that address both community concerns and the welfare of community cats, ultimately contributing to improved urban cat management in China. Managing community cats in urban China is a contentious and emerging issue, with debates centering on the most effective and humane approaches. This study aimed to investigate public attitudes towards community cats and various management strategies. A survey was conducted involving 5382 urban residents in China. Their attitudes towards the positive and negative roles of community cats in urban areas and their support for different management methods were examined, including trap-and-kill, taking no action, centralized management, and trap–neuter–return (TNR) and its variations. Results indicated that 63% of participants were willing to coexist with community cats, 71% opposed trap-and-kill, and 61% agreed or strongly agreed with the TNR method and its variations. Older residents or those with higher incomes were more likely to support coexistence with community cats. In contrast, younger or lower-income residents were more likely to support non-coexistence. Residents in first- or second-tier cities (e.g., Beijing, Hangzhou, and Jinan Cities in China) were more inclined to support trap-and-kill and less likely to support coexistence than their counterparts in fourth-tier cities (e.g., county-level cities in China). Moreover, those with lower education or incomes were more supportive of trap-and-kill and taking no action as the methods to manage community cats than those with relatively higher education or incomes. Those with higher incomes held more positive attitudes towards community cats and were more supportive of TNR and its variations than their counterparts with lower incomes. Males were more inclined to support trap-and-kill and taking no action and less inclined to support centralized management and TNR than females. The implications of the findings on TNR with adoption programs in urban China are discussed. These novel findings underscore the need for targeted educational campaigns to promote humane and effective management strategies, addressing public concerns and community cats' welfare. The study's insights are critical for informing policy and improving community cat management in urban China. [ABSTRACT FROM AUTHOR]

Feralization is the process of domesticated animals returning to the wild and it is considered the counterpart of domestication. Molecular genetic changes are well documented in domesticated organisms but understudied in feral populations. In this study, the genetic differentiation between domestic and feral cats was inferred by analysing whole-genome sequencing data of two geographically distant feral cat island populations, Dirk Hartog Island (Australia) and Kaho'olawe (Hawaii) as well as domestic cats and European wildcats. The study investigated population structure, genetic differentiation, genetic diversity, highly differentiated genes, and recombination rates. Genetic structure analyses linked both feral cat populations to North American domestic and European cat populations. Recombination rates in feral cats were lower than in domestic cats but higher than in wildcats. For Australian and Hawaiian feral cats, 105 and 94 highly differentiated genes compared to domestic cats respectively, were identified. Annotated genes had similar functions, with almost 30% of the divergent genes related to nervous system development in both feral groups. Twenty mutually highly differentiated genes were found in both feral populations. Evolution of highly differentiated genes was likely driven by specific demographic histories, the relaxation of the selective pressures associated with domestication, and adaptation to novel environments to a minor extent. Random drift was the prevailing force driving highly divergent regions, with relaxed selection in feral populations also playing a significant role in differentiation from domestic cats. The study demonstrates that feralization is an independent process that brings feral cats on a unique evolutionary trajectory. [ABSTRACT FROM AUTHOR]

Many neurodegenerative diseases (NDD) appear to share commonality of origin, chronic ER stress. The endoplasmic reticulum (ER) is a dynamic organelle, functioning as a major site of protein synthesis and protein posttranslational modifications, required for proper folding. ER stress can occur because of external stimuli, such as oxidative stress or neuroinflammatory cytokines, creating the ER luminal environment permissive for the accumulation of aggregated and misfolded proteins. Unresolvable ER stress upregulates a highly conserved pathway, the unfolded protein response (UPR). Maladaptive chronic activation of UPR components leads to apoptotic neuronal death. In addition to other factors, physiological responses to stressors are emerging as a significant risk factor in the etiology and pathogenesis of NDD. Owned cats share a common environment with people, being exposed to many of the same stressors as people and additional pressures due to their "quasi" domesticated status. Feline Cognitive Dysfunction Syndrome (fCDS) presents many of the same disease hallmarks as human NDD. The prevalence of fCDS is rapidly increasing as more people welcome cats as companions. Barely recognized 20 years ago, veterinarians and scientists are in infancy stages in understanding what is a very complex disease. This review will describe how cats may represent an unexplored animal mimetic phenotype for human NDD with stressors as potential triggering mechanisms. We will consider how multiple variations of stressful events over the short-life span of a cat could affect neuronal loss or glial dysfunction and ultimately tip the balance towards dementia.

Simple Summary: Domestic cats kept in modern household environments are susceptible to various oral health issues, including halitosis, tartar accumulation, periodontal disease, and gingivitis. While these issues may initially go unnoticed, they can become challenging to manage as they progress. Proactive measures akin to human oral care, such as tooth brushing and dietary modifications, are crucial for preventing oral diseases in cats. Probiotics are widely employed in the prevention and treatment of oral diseases in humans, providing pet owners with a viable long-term preventive approach compared to brushing. Within this context, our study found that supplementing a composite probiotic formulation can inhibit potential pathogens in the oral cavity of cats and promote the growth of beneficial or commensal bacteria, potentially enhancing oral health in cats. Probiotics demonstrated effectiveness in modulating oral microbiota and improving oral health in humans and rodents. However, its effects and applications on the oral microbiota of cats remain underexplored. Twelve healthy cats were randomly assigned to a control group (CON) and a composite probiotic group (CPG) for a 42-day trial. The CPG diet included additional supplementation of Bifidobacterium animalis subsp. lactis HN019, Lactobacillus acidophilus NCFM, and Lactobacillus casei LC-11, each at approximately 1 × 1010 CFU/kg. On days 0 and 42, microbial samples were collected from the gingiva, tooth surfaces, and tongue of all cats for 16S rRNA gene sequencing. Bacteroidetes, Firmicutes, and Proteobacteria were the dominant phyla across all oral sites. The CPG treatment enriched seven genera, such as Moraxella, Actinomyces, and Frederiksenia in the gingiva. Meanwhile, Bergeyella and Streptococcus were enriched on the tooth surfaces, while Bergeyella, Flavobacterium, and Luteimonas were enriched on the tongue. Furthermore, the composite probiotic effectively suppressed eight genera, such as Bacteroides, Desulfovibrio, and Filifactor in the gingiva of CPG cats, as well as Helcococcus, Lentimicrobium, and Campylobacter on tooth surfaces, and Porphyromonas, Treponema, and Fusibacter on the tongue. These findings suggest that the composite probiotic used in this study modulates the feline oral microbiota by supporting beneficial or commensal bacteria and inhibiting oral pathogens, demonstrating potential to improve oral health in cats.

Tetanus is a toxigenic illness caused by the action of Clostridium tetani neurotoxin (TeNT), which results in partial or generalized muscle stiffness in infected mammals and birds. The disease is rarely reported in cats due to their innate resistance to the toxin. This multicentric retrospective study aimed to describe a significant population of cats with a diagnosis of tetanus and report their signalment, clinical and neurological signs, diagnostic findings, treatment, and outcome. A retrospective search through medical records from 11 referral centers in Europe resulted in the identification of 27 cases of feline tetanus from July 2005 to April 2023. These cases were further compared with previously reported cases in the veterinary literature. Young cats were more commonly represented than older cats, with a median age of 4 years. Clinical signs were initially characterized by a lame and/or stiff limb, near the primary injury site, in 17/26 (65%) cats. Signs were focal or multifocal in 21/27 (78%) cats of this study and one typical sign was the inability to flex the most severely affected limbs. Electrodiagnostic studies revealed characteristic changes, such as continuous spontaneous motor unit discharges in both agonist and antagonist muscles. Such studies are particularly useful in focal and multifocal cases and should be performed to further support the diagnosis. The toxin was successfully identified in one case using the mouse bioassay. Treatment included antibiotherapy (metronidazole) in most cases, muscle relaxants, appropriate nursing cares and handling of potential complications. Overall, the outcome appeared to be positive, with only 1/27 (3.7%) cats being euthanized due to financial restrains. 23/25 (92%) cats returned to an independent ambulatory capacity on all limbs within a median delay of 25 days. Mild to moderate longterm sequelae were reported in eight (30%) cats. This multicentric study is the first to bring together such a large number of cats affected with tetanus. Presentation of the disease in cats differs from that observed in humans and dogs, with most cats being locally affected. Compared to previous reports of tetanus, this series of cats had a better outcome overall, especially for cats affected with generalized tetanus. [ABSTRACT FROM AUTHOR]

Background: Babesiosis is a tick-borne infection caused by piroplasmid protozoa and associated with anemia and severe disease in humans, domestic animals and wildlife. Domestic cats are infected by at least six Babesia spp. that cause clinical disease. Methods: Infection with a piroplasmid species was detected by microscopy of stained blood smears in three sick cats from Israel. Genetic characterization of the piroplasmid was performed by PCR amplification of the 18S rRNA, cytochorme B (CytB) and heat shock protein 70 (HSP70) genes and the internal transcribed spacer (ITS) locus, DNA sequencing and phylogenetic analysis. In addition, Haemaphysalis adleri ticks collected from two cats were analyzed by PCR for piroplasmids. Results: The infected cats presented with anemia and thrombocytopenia (3/3), fever (2/3) and icterus (1/3). Comparison of gene and loci sequences found 99–100% identity between sequences amplified from different cats and ticks. Constructed phylogenetic trees and DNA sequence comparisons demonstrated a previously undescribed Babesia sp. belonging to the Babesia sensu stricto (clade X). The piroplasm forms detected included pear-shaped merozoite and round-to-oval trophozoite stages with average sizes larger than those of Babesia felis, B. leo and B. lengau and smaller than canine Babesia s.s. spp. Four of 11 H. adleri adult ticks analyzed from cat # 3 were PCR positive for Babesia sp. with a DNA sequence identical to that found in the cats. Of these, two ticks were PCR positive in their salivary glands, suggesting that the parasite reached these glands and could possibly be transmitted by H. adleri. Conclusions: This study describes genetic and morphological findings of a new Babesia sp. which we propose to name Babesia galileei sp. nov. after the Galilee region in northern Israel where two of the infected cats originated from. The salivary gland PCR suggests that this Babesia sp. may be transmitted by H. adleri. However, incriminating this tick sp. as the vector of B. galilee sp. nov. would require further studies.

Background & Objective: Polycystic ovary syndrome is the prevailing endocrine disorder in females and one of the main causes of anovulatory sterility. It is associated with symptoms, disturbs females of reproductive age and affects their quality of life. Cathepsins are proteases that perform a variety of physiological tasks, including activating the complement system, regulating the immune system, and regulating, tissue homeostasis, and ion channel functioning. There are various subtypes, including aspartic, cysteine, and serine cathepsins. Cat S belongs to the family of cysteine cathepsin proteases. A lysosomal protease can encourage the endo-lysosomal pathway's destruction of undesirable or damaged proteins. The present study was conducted with aim to investigate the relationship between cathepsin S and Insulin Resistance in Iraqi women with PCOS. Materials & Methods: An Observational Case-Control Study was performed. The levels of cathepsin S, Insulin, glucose, and insulin resistance were evaluated for 135 blood samples (90 patients and 45 controls). Cathepsin S and Fasting Insulin were estimated by sandwich ELISA method, while glucose was performed using the COBAS INTEGRA 400 plus analyzer. Insulin resistance was calculated by the HOMA-IR formula. All the test procedures were performed at the College of Medicine’s Research Unit /Al-Nahrain University/ Baghdad-Iraq. The study was conducted from December to the end of March of 2023. Results: The levels of cathepsin S, Insulin, HOMA-IR, and glucose were elevated among PCOS patients with a high significant difference (HS) (P<0.0001) between the patient and the control groups. Conclusion: According to the results of this study, Cat S has the potential to be a novel vital component among PCOS parameters. Insulin Resistance continues to rise among PCOS women leading to a necessity for studying its specific mechanism and its genetic origins. [ABSTRACT FROM AUTHOR]

Background: Although regular health screening is recommended, long‐term follow‐up data in healthy aged cats are lacking. Objectives: Determine the most common conditions in a large group of apparently healthy older cats and which diseases are manifested within 2 years in cats confirmed to be healthy based on extensive health screening. Animals: Client‐owned cats. Methods: Prospective study. Thorough history, physical examination, blood tests, and urinalysis were performed in 259 apparently healthy mature adult (7‐10 years) and senior (>10 years) cats. Semi‐annual follow‐up examinations were performed in 201 confirmed healthy cats. Results: At baseline, 21% of apparently healthy cats were not considered healthy but were diagnosed with International Renal Interest Society (IRIS) ≥ stage 2 chronic kidney disease (CKD; 7.7%) or hyperthyroidism (4.6%), among other disorders. Disease occurred significantly more frequently in senior cats compared with mature adult cats. In addition, 40% cats were overweight, 35% had moderate to severe dental disease, and 22% had abnormal cardiac auscultation findings. Within 2 years, 28% of mature adult and 54% of senior cats that were confirmed healthy at inclusion developed new diseases, most commonly IRIS ≥ stage 2 CKD (cumulative incidence, 13.4%), hyperthyroidism (8.5%), chronic enteropathy, hepatopathy or pancreatitis (7.5%), or neoplasia (7%). Conclusions and Clinical Importance: The high prevalence and 2‐year incidence of physical examination abnormalities and systemic diseases in apparently healthy older cats argue for regular health screening in cats ≥7 years of age. Although more common in senior cats, occult disease also occurs in mature adult cats, and owners should be informed accordingly. [ABSTRACT FROM AUTHOR]

Motivated by the technological advancements in computer-assisted translation (CAT) tools and the notable lack of academic research regarding their application in the Arabic-translation context, this study aims to investigate the differences in translators’ performance when comparing traditional human translation and post-edited CAT tool-generated text in terms of speed and effort. This study investigates the performance of professional translators in Saudi Arabia through traditional translation from scratch (TFS) and postediting (PE) approaches. Data was collected from nine translators with 5–12 years of experience who had exposure to CAT tools. The participants translated an Arabic educational article into English using both methods. This study utilized Phrase CAT and Translog-II software to analyze the participants’ time and keystrokes. The results indicate that PE was significantly faster than TFS, with PE requiring 65.1% less time. PE also demanded significantly fewer keystrokes, suggesting lower technical effort. Correlations between keystrokes and time indicate a strong positive relationship in PE, implying that more technical effort correlates with increased temporal effort. These findings emphasize the efficiency of PE in enhancing productivity and suggest the importance of CAT tools and PE training for translators to meet industry demands effectively. Furthermore, this study underscores the need for continuous updates in CAT tool courses and the integration of PE training to prepare translators for constantly evolving technological landscapes.

Background: Although salmonellosis is considered to be a foodborne zoonotic disease, pets can play a significant role in the dissemination of antimicrobial‐resistant Salmonella organisms to humans because of close contact with their owners. Objectives: To determine the prevalence, risk factors, virulence factors, serotypes, and antimicrobial resistance profile of Salmonella in pet dogs and cats in Turkey and to assess the public health risk. Furthermore, to perform macroscopic comparison of lactic acid bacteria (LAB) in Salmonella‐positive and Salmonella‐negative animals. Methods: International Standards Organization (ISO) 6579‐1:2017 and Food and Drug Administration (FDA) methods were used to compare the effectiveness of culture methods in the identification of Salmonella in 348 rectal swabs. Positive isolates were serotyped using the slide agglutination method according to the White‐Kauffmann‐Le Minor scheme and the presence of virulence genes (invA and stn) were evaluated by polymerase chain reaction (PCR). Antimicrobial activity was tested by Kirby–Bauer disk diffusion method according to Clinical and Laboratory Standards Institute (CLSI) guidelines. Results: Salmonella prevalence was 5.73% (9/157) in dogs and 0.0% (0/191) in cats. Eight (8/9) isolates were cultured with the ISO method and 5 (5/9) isolates were cultured with the FDA method. Macroscopic results revealed that Salmonella agents had no effect on LAB. Three different serotypes were detected and all isolates were positive for virulence genes. Antibiotic resistance profiling indicated that 11.1% of the isolates were MDR and the highest resistance was found for ciprofloxacin. MDR‐resistant S. Virchow and carbapenem‐resistant S. Enteritidis were detected from dog isolates. There was a significant difference between raw meat consumption and Salmonella carriage (p < 0.01). Conclusions: Dogs could be potential carriers of Salmonella infection. The isolation of Salmonella in healthy dogs instead of dogs suffering from diarrhoea indicates that attention should be paid to asymptomatic carriage. The emergence of resistance among zoonotic Salmonella isolates poses a significant threat to public health. [ABSTRACT FROM AUTHOR]

Background: Sarcoptic mange is rare in cats. The main symptoms reported in cases of feline sarcoptic mange include crusty lesions and pruritus, although these may vary in severity among individuals. Objectives: This report describes three cats infested with Sarcoptes scabiei, all presenting with pruritus and excoriation. Methods: The diagnosis was confirmed by microscopic observation of skin scrape samples. Results: All three cats were treated successfully using moxidectin and imidacloprid, selamectin and ivermectin, respectively. Conclusions: The clinical presentation of feline scabies appears to be more variable in cats than in dogs. Infestation with S. scabiei should be considered a differential diagnosis for cats presenting with pruritic inflammatory skin disease. [ABSTRACT FROM AUTHOR]

Simple Summary: Aesthetic traits are major components of modern feline breeds. Each breed is defined by a standard specifying morphology; coat length, texture, and colour; and eye colour. Considering the coat and eye colour may help breeders in managing their breeding stocks to optimise their mating, but it also has an impact on the health and well-being of cats. Indeed, some colours and patterns may be associated with deleterious traits. Recently, a new coat and eye pattern has been described in cats. It has been called "dominant blue eyes (DBE)" and includes one or two blue eyes or particolored eyes and minimal white spotting. Different feline breeding lines were developed for DBE, and in some lineages, deafness has been identified as being associated with this trait. The Altai and Topaz breeds were created using DBE founding cats found in Kazakhstan and Russia. The Celestial breed, recognised in France, was created using a DBE outbred male from Kazakhstan and British shorthair and longhair cats. Other breeds, including the Maine Coon, British, Persian, Siberian, Sphynx, and Munchkin cats, introduced DBE. We have previously identified two variants associated with DBE, and here, we report the discovery of a third DBE variant. Finally, we review the presence of the three DBE variants in 14 feline breeding lines. During the last twenty years, minimal white spotting associated with blue eyes was selected by feline breeders to create the Altai, Topaz, and Celestial breeds. Additionally, certain breeders introduced this trait in their lineages of purebred cats. The trait has been called "dominant blue eyes (DBE)" and was confirmed to be autosomal dominant in all lineages. DBE was initially described in outbred cats from Kazakhstan and Russia and in two purebred lineages of British cats from Russia, as well as in Dutch Maine Coon cats, suggesting different founding effects. We have previously identified two variants in the Paired Box 3 (PAX3) gene associated with DBE in Maine Coon and Celestial cats; however, the presence of an underlying variant remains undetermined in other DBE breeding lines. Using a genome-wide association study, we identified a single region on chromosome C1 that was associated with DBE in British cats. Within that region, we identified PAX3 as the strongest candidate gene. Whole-genome sequencing of a DBE cat revealed an RD-114 retrovirus LTR (long terminal repeat) insertion within PAX3 intron 4 (namely NC_018730.3:g.206975776_206975777insN[433]) known to contain regulatory sequences. Using a panel of 117 DBE cats, we showed that this variant was fully associated with DBE in two British lineages, in Altai cats, and in some other DBE lineages. We propose that this NC_018730.3:g.206975776_206975777insN[433] variant represents the DBEALT (Altai Dominant Blue Eye) allele in the domestic cat. Finally, we genotyped DBE cats from 14 lineages for the three PAX3 variants and showed that they were not present in four lineages, confirming genetic heterogeneity of the DBE trait in the domestic cat.

Simple Summary: Cancer of the lymphatic system is a prevalent disease in dogs and cats, with older pets being the most affected group. However, it is crucial to recognize that animals of any age can develop this condition. Intestinal lymphoma, a type of neoplasm, arises when lymphocytes—white blood cells—become cancerous and proliferate uncontrollably. Recent research suggests that the microbiota, the community of bacteria and other microorganisms in the intestines, may play a role in the development of various diseases, including intestinal lymphoma. A healthy microbiota supports the immune system and prevents harmful cellular changes. In contrast, an imbalance in these microorganisms, potentially caused by poor diet, antibiotic use, or illness, can lead to inflammation and increase the risk of cancer. Recent advancements have significantly enhanced our understanding of the crucial role animal microbiomes play in veterinary medicine. Their importance in the complex intestinal environment spans immune modulation, metabolic homeostasis, and the pathogenesis of chronic diseases. Dysbiosis, a microbial imbalance, can lead to a range of diseases affecting both individual organs and the entire organism. Microbial disruption triggers inflammatory responses in the intestinal mucosa and disturbs immune homeostasis, increasing susceptibility to toxins and their metabolites. These dynamics contribute to the development of intestinal lymphoma, necessitating rigorous investigation into the role of microbiota in tumorigenesis. The principles explored in this study extend beyond veterinary medicine to encompass broader human health concerns. There are remarkable parallels between the subtypes of lymphoproliferative disorders in animals and humans, particularly Hodgkin's lymphoma and non-Hodgkin's lymphoma. Understanding the etiology of a cancer of the lymphatic system formation is critical for developing both preventive strategies and therapeutic interventions, with the potential to significantly improve patient outcomes. The aim of this study is to discuss the optimal composition of the microbiome in dogs and cats and the potential alterations in the microbiota during the development of intestinal lesions, particularly intestinal lymphoma. Molecular and cellular analyses are also incorporated to detect inflammatory changes and carcinogenesis. A review of the literature on the connections between the gut microbiome and the development of lymphomas in dogs and cats is presented, along with potential diagnostic approaches for these cancers.
