Intraspecific communication among carnivores can be complex and risky, and many solitary carnivores (including pumas; Puma concolor) primarily communicate with potential mates and competitors indirectly via scent marking at communication hubs. We used multiple temporal analyses to understand if pumas of three classes (males, solo females, and females traveling with dependent kittens) varied in their temporal use of communication hubs to reduce risk while gathering information. We hypothesized that males would visit scrapes at typical times (nighttime), but that female behavioral strategies might vary based on whether they had dependent kittens or not. We found that pumas of different classes varied in their temporal patterns: male pumas concentrated their temporal activity at night (which is typical for pumas), solo females also tended to visit during the nighttime (although slightly earlier on average than males), while females with kittens were more active in the daytime. Our findings highlight the importance of communication hubs for intersexual communication in pumas and the flexibility that is inherent in puma behavioral ecology. Females adjusted their temporal behavior and visitation based on their reproductive status and life history stage, likely to assess dominant territorial males while also limiting their risk. Our study provides a mechanistic view of how communication through scent marking allows both long‐term and spatially separated communication to occur and that may allow pumas at different life stages with different risk tolerances to communicate with each other.

In the feline species, the mortality of live-born kittens over the first 2 months of life is around 10%. Although some losses are inevitable, progress in veterinary medicine and improved knowledge of feline neonatalogy should make it possible to reduce them to a lower level. The objectives of this study were: (i) to describe early growth in kittens, and (ii) to assess whether low birth weight kittens develop compensatory growth during the first week of life and if so, whether compensatory growth is associated with increased chances of survival. Using data collected from 5,504 kittens born in 193 different French catteries, five growth rates were calculated to reflect the growth of kittens during the first week after birth. Low birth weight kittens had higher growth rates than normal birth weight kittens. In addition, low birth weight kittens whose early growth was in the lowest 25% had a significantly higher 0-2 months mortality rate than all the other groups. Weight loss (or lack of weight gain) between birth and Day 2 was identified as a risk factor for 0-2 months mortality whatever the birth weight category. Finally, critical early growth thresholds were determined separately for low and normal birth weight kittens. These figures could help caregivers to validate the adequacy or inadequacy of kitten early growth. They will be able to quickly identify and provide appropriate care for the kittens whose growth is deemed insufficient in order to improve their chances of survival. [ABSTRACT FROM AUTHOR]

A 3-month-old kitten was presented after successful cardiopulmonary resuscitation, including a presumed intracardial injection by its primary care veterinarian. Throughout the subsequent hospitalization in the intensive care unit, the cat exhibited recurrent hemorrhagic pericardial effusions, along with concurrent pleural and abdominal effusions, resulting in multiple clinical deteriorations, necessitating pericardiocentesis and thoracocentesis. Despite more than 3  days of intensive care, the cat experienced another cardiopulmonary arrest with unsuccessful attempts to achieve the return of spontaneous circulation. Necropsy and histopathological findings revealed diffuse chronic)active pericarditis and hemorrhagic pericardial effusion, a condition that has not been documented in the context of cardiopulmonary resuscitation or pericardiocentesis.

The article determines the in vivo insecticidal activity of the antiparasitic drug "Superium Panacea" for cats. It has been established that the drug "Superium Panacea" has a pronounced insecticidal effect on wingless ectoparasitic insects Ctenocephalides felis and acaricidal effect on sarcoptoid ticks Otodectes cynotis. The duration of the protective effect of the drug was at least 28 days. The drug "Superium Panacea" with a wide spectrum of insecticidal and acaricidal action when applied to cats and kittens orally (peros), individually, once, during morning feeding with a small amount of feed or forcibly, according to the manufacturer's recommended schemes, is well tolerated by animals of different breeds and ages, which were used in the study and can be used for the treatment and prevention of mixed parasitosis.

Objective: This study aimed to detect Toxocara cati in cats by microscopic and molecular analysis using PCR, sequencing, and phylogenetic analysis. Materials and Methods: Randomly selected 200 cat feces samples were taken from various private veterinarian clinics in Baghdad. To identify eggs of T. cati by the flotation method, DNA from 100 cat feces was extracted, and one pair of ITS2 region-specific primers was used for polymerase chain reaction, followed by sequencing. Results: Toxocara cati infection rate was found to be 23 out of 100 fecal samples using PCR. Ten DNA product sequence data studies showed 98%-100% similarity to the 5.8S ribosomal RNA gene sequences found in the Gene Bank. The study incidence showed that the overall infection rate by microscopic examination was 23%, with no significant difference between stray cats (27%), and domestic cats (19%). After studying the effect of several epidemiological parameters on the infection rate, it was found that the infection rates of stray and domestic cats were higher in kittens under six months of age, at 46.1% and 27%, respectively, whereas rates were lower for the adult than six months was 11.5% of domestic cats and 14.7% of stray cats. The percentage of stray and domestic male cats that were registered was 35.5%, whereas the female cats registered were 20.6% and 17.5%, respectively. Conclusion: Cats are significant clinical reservoirs for zoonotic parasites. In Iraq, Baghdad has a high incidence of T. cati detections. Compared to conventional methods, PCR is thought to be a more sensitive, accurate diagnostic procedure that confirms the species' identity. [ABSTRACT FROM AUTHOR]

Background: Vitamin D deficiency and excess in clinically presented cats conventionally is diagnosed by comparison of patient plasma 25-hydroxyvitamin D (25 (OH)D) concentration with plasma reference intervals determined in healthy adult cats. For immature cats, validity of this vitamin D status assessment method is uncertain. Objective: The overall objective was determination of whether plasma concentration of 25 (OH) D and other vitamin D metabolites in immature cats markedly change with developmental age as has been reported in other species. Methods: Four male and 4 female domestic short-hair kittens from weaning were continuously presented a single nutritionally adequate growth-diet. Concentrations of 25 (OH) D and 24,25-dihydroxyvitamin D (24,25 (OH)²D), and calcitriol were quantified in plasma of jugular venous blood collected at 12, 15, 18, and 21 weeks and 1 year of age. Plasma was liquid and solid-phase extracted and fractionation by normal-phase HPLC, and 25 (OH) D and 24,25 OH)2D quantified by reverse-phase HPLC-UV and calcitriol by RIA. Results: Plasma 3-epi-25 (OH) D and 25 (OH) D concentrations increased (p < 0.001) with age so that by study end the concentrations rose by 1-and 2-fold, respectively. Concentrations of 3-epi-25 (OH) D relative to 25 (OH) D were 30% at 12 weeks and 20% at 1 year. Between ages 12 and 21 weeks, rises in 25 (OH) D concentration were positively correlated with body weight gains (ρ = 0.952, p < 0.001) and 24,25 (OH)2D concentrations were consistently greater than 25 (OH) D concentrations (p < 0.001). At 1 year of age, concentrations of 24,25 (OH)2D declined below those of 25 (OH) D and 3-epi-24,25 (OH)2D consistency occurred in low concentrations. Vitamin D2 metabolites and sex differences in metabolite concentrations were not observed. Conclusion: Reliance on quantification of plasma 25 (OH) D concentration for vitamin D status assessment in kittens may be confounded by developmental changes in 25 (OH) D independent of vitamin D intake. High 24,25 (OH)2D concentration and occurrence of 3-epi-25 (OH) D in plasma additionally may interfere with the quantification. [ABSTRACT FROM AUTHOR]

Bobcats (Lynx rufus) are the most broadly distributed native felid in North America and have substantial ecological and economic importance. Despite this importance, little is known about factors influencing population dynamics of this cryptic carnivore. Given recent apparent declines in abundance, we investigated population growth rate (λ) for a bobcat population in the Black Hills, South Dakota, USA, 2016–2022. We constructed and evaluated a females‐only matrix population model. Our estimate of asymptotic λ, derived from estimates of vital rates obtained over 6 years, was 0.85 (95% CI = 0.72, 1.02), which indicates that the vital rates in 2016–2022 were inadequate to sustain the population. Elasticity and sensitivity values were highest for changes in adult survival probability followed by, in order, changes in kitten and juvenile survival and adult reproductive contribution. Life‐stage simulation analysis also supported that adult survival was most important; however, the juvenile survival (91 day–1 year) component of a bobcat's first year of life was also important and a stronger influence on population growth than the kitten survival (first 90 days) component. For the combination of survival and reproductive rates we estimated positive population growth required either annual adult survival >0.85 or 275‐day juvenile survival >0.35, regardless of other vital rates. When assuming a baseline harvest rate of 23.5%, reducing the harvest rate to 9% led to a positive mean growth rate and a >0.50 probability of a growing population. Monitoring juvenile‐to‐adult harvest ratios can provide an indicator of age structure in the population, and we recommend restricting harvest when that ratio falls below 10%, particularly when managers lack research information on population growth.

A 6-month-old Ragdoll and 9-year-old Russian Blue cat presented with vomiting. Ultrasonography and computed tomography showed a pyloric antrum mass with wall layering loss and regional lymphadenopathy in the Ragdoll kitten. The Russian Blue cat only presented with muscularis layer thickening throughout the jejunum; however, despite medications, it later progressed to a mass with wall layering loss on the serial ultrasound. Both cats underwent surgery, and feline gastrointestinal eosinophilic sclerosing fibroplasia (FGESF) was histologically confirmed. FGESF should be considered for gastrointestinal masses demonstrating wall layering loss and lymphadenopathy, even in kittens, and intestinal muscularis layer thickening that is refractory to medications.

The prevalence, intensity, or outcome of interference competition and interspecific killing between predominantly solitary species operating on large spatial scales is challenging to document or test. Here, we present a detailed account of inter‐ and intraspecific interactions from contemporaneous GPS location data and in‐field investigation. In June 2018, a GPS‐collared female cougar (Puma concolor) maintained strong site fidelity for a period of 19 days, indicative of parturition behavior and establishment of a nursery site. In early July 2018, three GPS‐collared black bears (Ursus americanus) arrived at the nursery site, after which the female cougar abandoned the site. Site investigation showed that one or more bears predated an unknown number of cougar kittens. The evidence supports ecological theory suggesting that body size, mass, or group number is an important predictor of outcome. Our observation provides an example of bears potentially making risk–reward trade‐offs by eliminating a potential competitor that at the same time provisions carrion as critical food resources. These real‐time inter‐ and intraspecies competitive interactions as documented using GPS collars allow for greater insight into individual fitness and community‐level effects. [ABSTRACT FROM AUTHOR]

Background: Benzalkonium chloride (BAC) is a quaternary ammonium compound (QAC), that can be found in a wide variety of household products–from disinfectants to medicaments and home fragrances–but also professional products. In pets, cats have long been reported as more sensitive than dogs to QACs; in fact, signs of irritation such as oral ulcerations, stomatitis and pharyngitis can be observed after contact with concentrations of 2% or lower. In a review of 245 cases of BAC exposure in cats, reported by the Veterinary Poisons Information Service (United Kingdom) only 1.2% of the cases died or were euthanized. Nevertheless, BAC toxidromes in cats can result in transitory CNS and respiratory distress, as well as severe mucosal and cutaneous lesions. Currently, only a few reports are available concerning BAC poisoning in this species. Case presentation: A 4 month-old kitten presented with severe glossitis, lameness in the hindlimbs and episodes of vomiting and diarrhoea. The cause was unknown until the owners reported use of a BAC-containing mould remover (5%) 4 days later. The patient developed severe oral burns requiring a pharyngeal tube for feeding and severe cutaneous chemical burns. The kitten was managed with supportive therapy and required hospitalization for 10 days. The symptoms disappeared completely 3 weeks after exposure. Conclusions: BAC is a very common compound contained in several household and professional products but, to the best of our knowledge, no previous case had been reported in Italy. We hope that this report will help raise awareness on the hazards of BAC products for cats in both domestic and work contexts. [ABSTRACT FROM AUTHOR]

Simple Summary: While it is widely believed that feline infectious peritonitis (FIP) is a dangerous epidemic disease, the prevalence of FIP in Chinese cats is currently unknown. Our findings indicate that the prevalence of FIP in Chinese cats is influenced by age, gender, and breed. We recommend controlling the scale of cat breeding, enhancing cat immunity, and particularly focusing on health management in kittens and continuous monitoring of FIP in cats. To evaluate the overall prevalence of FIP infection in cats in mainland China and associated risk factors, studies on the prevalence of FIP conducted from 1 January 2008 to 20 December 2023 were retrieved from five databases—CNKI, Wanfang, PubMed, Web of Science, and ScienceDirect—and comprehensively reviewed. The 21 studies selected, with a total of 181,014 samples, underwent a rigorous meta-analysis after quality assessment. The results revealed a 2% prevalence of FIP (95% CI: 1–2%) through the random-effects model, showing considerable heterogeneity (I2 = 95.2%). The subsequent subgroup analysis revealed that the age and gender of cats are significant risk factors for FIP infection in mainland China. In order to effectively reduce and control the prevalence of FIP on the Chinese mainland, we suggest improving the immunity of cats, with special attention given to health management in kittens and intact cats, and continuously monitoring FIPV.

Extended maternal care, defined by protection, nursing and training of young, is a hallmark of mammalian reproduction. Prior maternal experience and maternal caregiving decisions during rearing may influence the success of offspring. Because most maternal caregiving behaviour, such as nursing and defence, requires contact or close proximity to the young, time spent with offspring may be a good proxy for maternal care provision when direct maternal behaviour is unobservable. Although different behavioural patterns can influence how carnivore mothers balance the competing energetic costs of brood raising and food acquisition, relatively little is known about the allocation of maternal care to neonates in solitary felids, such as cougars, Puma concolor. To evaluate how maternal behaviour and provisioning affect kitten survival, we remotely monitored 16 female cougars and their 49 neonate kittens using proximity-linked VHF collars on neonates and paired GPS collars on adults. We deployed collars on 5.5-week-old kittens and monitored their survival to 180 days postbirth. We derived several metrics to quantify maternal care behaviours and fitted Bayesian known-fate survival models to estimate the daily survival probability of kittens and to evaluate the influence of maternal behaviour on kitten survival. We found that kittens who received increased levels of maternal care, such as more time with their mother each day, had higher survival rates among both first-time and experienced mothers. However, experienced mothers exhibited higher kitten survival across all scenarios compared to first-time mothers. Our results suggests that prior maternal experience is a strong driver of increased kitten survival rates and that kitten survival rates are increased when mothers provide more maternal care. • For many mammals, maternal caregiving can be influential to survival of young. • Maternal care or prior experience may lead to better kitten survival outcomes. • rVHF collars on neonates can provide information about proximity to the mother. • Cougar kitten survival was higher from mothers who had previously raised kittens. • Maternal caregiving increased kitten survival for first-time and experienced moms.

Introduction: The domestic cat (Felis catus) is one of the most common pets. Worldwide, approximately one in five adults are sensitive to cat allergens. The major cat allergen is the secretoglobulin Fel d 1, which is primarily produced in the salivary and sebaceous glands. Chickens produce IgY antibodies, which are similar in structure to mammalian IgG. When chickens are exposed to Fel d 1, anti-Fel d 1-specific IgY (AFD1) is produced and is naturally concentrated in egg yolk. The aim of this study was to evaluate the tolerability, effects on growth and food consumption, and potential adverse effects of a chicken egg product ingredient containing AFD1 in kittens. Methods: This was a blinded, controlled study. Twenty-seven (27) eight-week old kittens were randomly assigned to three feeding groups containing 0 ppm AFD1 (Group 0), 8 ppm AFD1 (Group 1), and 16 ppm AFD1 (Group 2) for 84 days. Veterinary exams and bloodwork were performed on Day 42 and Day 84, and body weight and body condition score (BCS) were monitored weekly. Results: Throughout the study, there were no signs of nutritional deficiency or adverse clinical events in any of the subjects. Administration of a chicken egg product ingredient containing AFD1 in the diet (whether in coating or combination of coating and top dress) had no significant effect on body weight nor food consumption, and all subjects maintained a healthy Body Condition Score (BCS) throughout the study. Moreover, there were no biologically significant differences in the mean clinical chemistry and hematology parameters. Discussion: This study demonstrated that a diet formulated to contain up to 16 ppm AFD1, included in the coating and the top-dress of dry kitten food, was well tolerated, promoted adequate growth, and exhibited no adverse effects.

Feline parvovirus (FPV) is highly infectious for cats and other Felidae and often causes severe damage to young kittens. In this study, we incorporated recombinase polymerase amplification (RPA) and Cas12a-mediated detection and developed an RPA-Cas12a-based real-time or end-point fluorescence detection method to identify the NS1 gene of FPV. The total time of RPA-Cas12a-based fluorescence assay is approximately 25 min. The assay presented a limit of detection (LOD) of 1 copies/μl (25 copies/per reaction), with no cross-reactivity with several feline pathogens. The clinical performance of the assay was examined using total genomic DNA purified from 60 clinical specimens and then compared to results obtained with qPCR detection of FPV with 93.3% positive predictive agreement and 100% negative predictive agreement. Together, the rapid reaction, cost-effectiveness, and high sensitivity make the RPA-Cas12a-based fluorescence assay a fascinating diagnostic tool that will help minimize infection spread through instant detection of FPV.

• Drama-based storytime encourages preschoolers to embody story characters. • In theories of embodied cognition, gesture and movement support learning. • Intervention group children experienced drama-based story-times. • Intervention group children used more gesture/body movement during narrative retell. • Gesture and body movement during narrative retell predicted free retell scores. Oral narrative comprehension is an important precursor to reading comprehension. Supporting preschool students in building strong oral narrative comprehension skills prepares them to be successful once they enter formal schooling. Gesture and body movement have been shown to support children's oral narrative comprehension and recall skills. This study examines whether drama-based instruction (DBI)—an organic, inherently gesture- and movement-based approach to teaching—during storytime fosters preschool children's narrative comprehension and recall. In this paper, we compare story retells by preschool students who participated in a DBI storybook reading (n = 90) with retells by preschool students who heard the same book during a business-as-usual (BAU) storytime (n = 106). Results show that using embodied behaviors (i.e., gesture, facial expression, body movement, vocal change) during story retelling was associated with recalling more story elements during a free retell task (when children are asked to retell the story without additional prompts), although not during a prompted retell task (when children retell the story by responding to questions). Students who participated in the DBI storytime used twice as many story-relevant embodied behaviors during retell tasks compared to their BAU peers. Additionally, embodied behavior significantly mediated the relation between treatment status and free retell scores. This study offers promising evidence as to the efficacy of using drama-based storytime in preschool classrooms to support listening comprehension and recall of oral narratives. Findings support a theory of embodied language learning and suggest potential benefits of drama to enhance literacy learning. [ABSTRACT FROM AUTHOR]

Immune deficiency is a prevalent issue among kittens, severely threatening their health and development by increasing susceptibility to infections and diseases. This study investigates the effects of dietary supplements containing lactoferrin and Lactobacillus plantarum (L. plantarum) on the immune function, intestinal health, and microbiota composition of kittens. The results demonstrate that these supplements significantly enhance immune responses, with immunoglobulin A (IgA) levels increasing by 14.9% and IgG levels by 14.2%. Additionally, there was a notable 28.7% increase in catalase activity, indicating a reduction in oxidative stress. Gastrointestinal (GI) health improved markedly, evidenced by increased populations of beneficial bacteria such as Lactobacillus, which rose from 4.13% to 79.03% over the study period. The DNC group also showed significant reductions in pro-inflammatory cytokines, including decreases of 13.94% in IL-2, 26.46% in TNF-α, and 19.45% in IFN-γ levels. Furthermore, improvements in physical conditions were observed, including enhanced coat condition and mental status. These findings underline the potential of lactoferrin and L. plantarum as effective dietary interventions to improve kitten health, thereby reducing dependency on antibiotics and mitigating associated risks. This research provides a scientific foundation for optimizing nutritional management practices to enhance the overall vitality of kittens during their critical growth phases.

Background: Congestive heart failure (CHF) is a pathological state characterized by the incapability of the heart to properly perform its essential function of delivering blood to meet the metabolic demands of the body. Case Description: The present case report concerns a 3-month-old male domestic kitten, displaying symptoms including an enlarged abdomen, emaciation, dehydration, dyspnea, rhinorrhea, and infestation with scabies. This animal, weighing 0.7 kg displays a tabby bicolor pattern. The findings gleaned from the clinical evaluation revealed the presence of a murmur upon auscultation of the cardiac region. Upon conducting an ultrasound examination, it was determined that the abdominal cavity contained a fluid accumulation known as ascites. Conclusion: The findings from the radiographic evaluation indicate that feline Hiro exhibits ascites alongside cardiomegaly, in conjunction with discernible vascular modifications characterized by both enlargements of the pulmonary arteries and veins.

Cats are the only definitive host of Toxoplasma gondii (T. gondii) that shed millions of un-sporulated oocysts. The current study aimed at evaluating the serological and histopathological potential ratio of T. gondii oocysts shedding and re-shedding kittens. Blood and fecal samples collected from fifty-seven un-weaned kittens from various districts of Cairo Governorate, Egypt. All kittens serologically screened for T. gondii using the Latex agglutination test (LAT), and fecal materials inspected daily for oocysts. Only proven seronegative un-shedding kittens employed in the three experimental re-shedding studies using the three T. gondii strain types II, III, and I with the third trial focusing on the ability of re-shedding with corticosteroid therapy. One kitten corresponding to each type sacrificed for histo-pathological assay and IgM/IgG serum antibodies recorded along the trials course using ELISA. The overall sero-negative percentage was 59.7%, with 35.1 and 24.6% in shedding and un-shedding ones respectively. The shedding number of oocysts /100 mg/feces scored (7, 5 and 3); (30, 15 and 7); (20, 10 and 5) corresponding and sequence to the three T. gondii strain types I, II and III respectively. In addition, the average IgM/IgG ELISA titers recorded significance variations sequence to the three strain types. Corticosteroids therapy stimulates re-shedding ability for the third time. The findings concluded that kittens shed oocysts at a high rate; regard shedding and re-shedding qualities as a critical component in developing oocyst-borne human and animal toxoplasmosis effects. Strong protection against vaccinated cats are required, as is close interaction between cats and farm animals. [ABSTRACT FROM AUTHOR]

Simple Summary: Newborns are susceptible to infectious disease, and early life represents a critical developmental window of the immune system, which is important for preventing and fighting disease. There is evidence that nucleotides, oligosaccharides and vitamins can positively influence immune function; however, the evidence that is specifically applicable to cats is limited. This current study fed domestic short hair kittens either a dry format control diet or a test diet fortified with nucleotides, short-chain fructooligosaccharides, xylooligosaccharides, β-carotene and vitamin E until the kittens reached 28 weeks of age. The kittens followed a routine preventative medication schedule for vaccination and a suite of health, metabolism and immune parameters were measured at regular intervals throughout the study. All kittens remained healthy and did not display any clinically relevant signs of adverse health. Antibodies are produced following infection or vaccination. The level of antibody, the proportion of kittens who demonstrated an acceptable response to vaccination and the proportion of kittens who reached the recognised protective level of antibody were greater in kittens fed the test diet. The test diet group demonstrated a stronger antibody-mediated response to vaccination. Antibodies play a role in preventing disease; thus, this suggests that the test diet supports immune defence against immune challenges. Nucleotides, short-chain fructooligosaccharides (scFOS), xylooligosaccharides (XOS), β-carotene and vitamin E are reported to enhance immune function; however, the evidence of this in cats is limited. The aim of this study was to determine the immunomodulatory effects of these ingredients in kittens. Forty domestic short hair kittens were designated in litters to control or test diet for 28 weeks. Test diet was fortified with 0.33 g nucleotides, 0.45 g scFOS, 0.3 g XOS, 0.7 mg β-carotene and 66.5 mg vitamin E per 100 g diet. Kittens were vaccinated against feline parvovirus (FPV) and herpesvirus (FHV) at 10, 14 and 18 weeks. Kittens remained healthy, with no measured evidence of adverse health. Serum FPV and FHV antibody titres were significantly (p < 0.05) higher in the test diet group at week 23 and 27, respectively. A significantly (p < 0.05) higher proportion of test diet group kittens demonstrated an adequate response (four-fold titre increase) to FHV vaccination and a significantly (p < 0.05) higher proportion reached a protective antibody titre for FHV. Serum IgM was significantly (p < 0.05) higher in the test diet group. The test diet group demonstrated a stronger humoral immune response to vaccination, suggesting the diet supports immune defence, enabling a greater response to immune challenges.

This article explores the participatory extension of humor in social media in connection with Burn's idea of produsage. Specifically, this work offers a discursive analysis of viewers' comments on the viral YouTube video Kitten Zoom Filter Mishap to unveil the ways in which the audience appropriated elements from the original content and broadened its humorous effect. The results of the analysis show a prevalence of textual comments conveyed through a variety of linguistic structures. Both the structures used and the meaning expressed through them transformed the video into a more humorous and culturally and linguistically complex artifact. This transformation, in turn, resulted in a new distinct social community among the video's viewers, expanding and at the same time limiting humor co-participation, which reflects YouTube's capacity for enabling produsage, but also constraining participation.

A 3‐month‐old, domestic, long‐haired cat presented dull and lethargic with a history of failure to thrive and persistent postprandial regurgitation. A barium oesophagram performed by the referring veterinarian identified a megaoesophagus terminating at the level of the fourth intercostal space. Computed tomography angiography confirmed the suspected vascular ring anomaly, classified as a persistent right aortic arch with a concurrent aberrant left subclavian artery. Surgical ligation and transection of the ligamentum arteriosum, while sparing the aberrant left subclavian artery via a left fourth intercostal thoracotomy, resulted in resolution of the oesophageal compression and clinical signs postoperatively. Follow‐up 22 weeks postoperatively showed marked improvement in weight and body condition score, with no regurgitation following the introduction of a solid consistency commercial diet. This report describes the complete resolution of clinical signs following surgical correction of this form of vascular ring anomaly while sparing the aberrant left subclavian artery, without the need for long‐term dietary or feeding modification.

The study was to investigate the effect of Astragali Radix, Chinese yam and Crataegus pinnatifida on growth performance, hair quality, fecal characteristics, serum antioxidant, immune indexes and gut microbiota of kittens. Eighteen kittens aged 45 to 60 days were randomly divided into three groups with six in each group and one kitten in each replicate. The kittens in blank control group (group H) was fed with the basic kitten diet, the kittens in experimental control group (group R) was fed with the commercial kitten diet, and experimental group (group T) was 0.2% Astragali Radix, 0.2% Chinese yam, 0.2% Crataegus pinnatifida in the basic kitten diet. The experiment lasted for 30 d. The results showed that the average daily gain of kittens in group T was higher than that in group H and group R, and the feed to gain ratio was lower than that in group H (P>0.05). The kittens in group T fur scale thickness and the degree of adhesion were higher. The serum GSH-Px activity of group T was significantly higher than that of group R (P<0.05). The fecal score of group T was higher than that of group H and group R (P>0.05), and the intestinal flora richness was higher and the flora structure was more similar. The experiment indicates that Astragali Radix, Chinese yam and Crataegus pinnatifida can raise kittens grow performance, excrement characters, hair quality, oxidation resistance and immunity, can optimize the structure of intestinal flora, thus more conducive to the healthy growth of kittens.

A prospective study was designed to (a) investigate the rate of daily weight gain among kittens less than 9 weeks old presented to an animal shelter, (b) identify factors (e.g., sex, clinical signs of disease, diet, and medical treatment) that affect daily weight gain, and (c) investigate the mortality of study kittens. The study of 203 kittens was conducted at a managed admission, no-kill animal shelter in upstate New York, USA, from April 2014 through October 2014. Body weight was measured daily from day of intake to adoption or 12 weeks of age. Fecal score, clinical signs of disease, food type, and medical treatments were recorded daily. Lethargy and being female were significantly associated with lower daily weight gain. Despite the challenges of shelter and foster care, the average daily weight gain for study kitten was higher than that reported in other settings such as catteries and laboratories. Five study kittens (2.5%) died or were euthanized. Daily monitoring systems provide opportunities for interventions, increased live outcomes, and improved welfare for kittens in shelter and foster care. [ABSTRACT FROM AUTHOR]

Blood and fecal samples collected from fifty-seven un-weaned kittens from various districts of Cairo Governorate, Egypt. All kittens serologically screened for T. gondii using the Latex agglutination test (LAT), and fecal materials inspected daily for oocysts. Only proven seronegative un-shedding kittens employed in the three experimental re-shedding studies using the three T. gondii strain types II, III, and I with the third trial focusing on the ability of re-shedding with corticosteroid therapy. One kitten corresponding to each type sacrificed for histo-pathological assay and IgM/IgG serum antibodies recorded along the trials course using ELISA. The overall sero-negative percentage was 59.7%, with 35.1 and 24.6% in shedding and un-shedding ones respectively. The shedding number of oocysts /100 mg/feces scored (7, 5 and 3); (30, 15 and 7); (20, 10 and 5) corresponding and sequence to the three T. gondii strain types I, II and III respectively. In addition, the average IgM/IgG ELISA titers recorded significance variations sequence to the three strain types. Corticosteroids therapy stimulates re-shedding ability for the third time. The findings concluded that kittens shed oocysts at a high rate; regard shedding and re-shedding qualities as a critical component in developing oocyst-borne human and animal toxoplasmosis effects. Strong protection against vaccinated cats are required, as is close interaction between cats and farm animals.

We investigated 4 European domestic shorthair kittens with skin lesions consistent with the dermatosparaxis type of the Ehlers-Danlos syndrome, a connective tissue disorder. The kittens were sired by the same tomcat but were born by 3 different mothers. The kittens had easily torn skin resulting in nonhealing skin wounds. Both clinically and histologically, the skin showed thin epidermis in addition to inflammatory changes. Changes in collagen fibers were visible in electron micrographs. The complete genome of an affected kitten was sequenced. A one base pair duplication leading to a frameshift in the candidate gene ADAMTS2 was identified, p.(Ser235fs*3). All 4 affected cats carried the frameshift duplication in a homozygous state. Genotypes at this variant showed perfect cosegregation with the autosomal recessive Ehlers-Danlos syndrome phenotype in the available family. The mutant allele did not occur in 48 unrelated control cats. ADAMTS2 loss-of-function variants cause autosomal recessive forms of Ehlers-Danlos syndrome in humans, mice, dogs, cattle, and sheep. The available evidence from our investigation together with the functional knowledge on ADAMTS2 in other species allows to classify the identified ADAMTS2 variant as pathogenic and most likely causative variant for the observed Ehlers-Danlos syndrome.

Feline immunodeficiency virus (FIV) is a lentivirus in the family Retroviridae that infects domestic cats resulting in an immunodeficiency disease featuring a progressive and profound decline in multiple sets of peripheral lymphocytes. Despite compelling evidence of FIV-associated immunopathology, there are conflicting data concerning the clinical effects of FIV infection on host morbidity and mortality. To explore FIV-associated immunopathogenesis and clinical disease, we experimentally inoculated a cohort of four specific pathogen-free kittens with a biological isolate of FIV clade C and continuously monitored these animals along with two uninfected control animals for more than thirteen years from the time of inoculation to the humane euthanasia endpoint. Here, we report the results obtained during the late asymptomatic and terminal phases of FIV infection in this group of experimentally FIV-infected cats. [ABSTRACT FROM AUTHOR]

In cat breeding, an important step is reproduction and obtaining healthy offspring. The main factor determining the survival of newborn kittens is the normal course and length of pregnancy. The purpose of this study was to determine the effect of gestation length on the early development of kittens. It was shown that kittens (premature kittens) later double their body weight (p <.01), have lower daily gains (p <.01) and higher body weight during eye‐opening (p <.01), which occurs later than in kittens born on time. In addition, due to a shorter period of prenatal development, they require more time until the day of eye‐opening, which, together with the length of pregnancy, was defined as development age.

The Iriomote cat (Prionailurus bengalensis iriomotensis) is an endangered leopard cat that inhabits only Iriomotejima Island, Japan. The number of Iriomote cats is estimated to be approximately 100–110 and has been almost stable but slightly decreased in the coastal lowland. Infectious diseases are one of the major concerns in the conservation of Iriomote cats. Toxoplasma gondii is a protozoan parasite that causes toxoplasmosis. Toxoplasmosis is fatal in immunocompromised hosts, especially kittens and cat fetuses. We investigated the seroprevalence of T. gondii in Iriomote cats. Based on seroprevalence data, we simulated the effect of T. gondii infection on the population dynamics of Iriomote cats. The seroprevalence of T. gondii in Iriomote cats was significantly higher than that in domestic cats and dogs. Furthermore, the seroprevalence of T. gondii in domestic cats was significantly higher on Iriomotejima Island than on Okinawajima Island. Our simulation demonstrated that T. gondii eradication may help increase the population of Iriomote cats by an average of 11.5 (23.1%) cats in 2120. Therefore, controlling T. gondii may be an effective strategy for the conservation of Iriomote cats. [ABSTRACT FROM AUTHOR]

Quantitative abilities are well described in many species and in diverse life situations, including in the adult domestic cat. However, such abilities have been much less studied during ontogeny. In the present study we examined spontaneous quantity discrimination by pre-weaning age kittens in two-way food choice experiments. In Experiment 1, 26 kittens performed 12 trials with different ratios between the number of same-size food items. In Experiment 2, 24 other kittens performed eight trials with different ratios between the size of two food items. We found, in general, that the kittens discriminated between the different amounts of food and spontaneously chose the larger one, but that their choice was influenced by the ratio of difference. The kittens in Experiment 1 chose the larger number of same-size food items if the ratio was smaller than 0.4 and in Experiment 2 they chose the larger pieces of food if the ratio between the items was smaller than 0.5. Because the kittens' choice was not influenced by the absolute number of food items or the numerical difference between them in Experiment 1, it suggests that their cognitive performance relied on an analog magnitude system rather than on an object file system during the quantity discrimination tasks. We discuss our results considering the ecological and social background of cats and compare it with the performance of previously studied species. [ABSTRACT FROM AUTHOR]

The material of the case was a 3-year-old female mixed-breed cat which was brought to Selçuk University, Faculty of Veterinary Medicine, Department of Obstetrics and Gynaecology with the complaint of foul smelling vaginal discharge. According to the anamnesis, following the intervention of the owner, the cat was taken to a private veterinary clinic, where she underwent a cesarean section and ovariohysterectomy operation due to dystocia. It was reported that the cesarean section and ovariohysterectomy operation was performed successfully and there were no postoperative complications. Vaginal examination revealed a foul-smelling mucopurulent discharge. An experimental laparotomy was performed with the consent of the owner because of suspicion of Stumph's pyometra after ovariohysterectomy. Since it was determined that there was a hardness behind the cervix in the operation, the canal was controlled by vaginal swabbing. The vaginal canal was examined in detail due to the presence of discharge and the swab touching hard structures. During the examination, it was determined that the structures attached to the end of the swab were bone and that the head, which had been severed during dystocia, had been left in the vaginal canal. Bone fragments of the cranium of the resorbed puppy were removed and cleaned using long-toothed forceps. Failure to analyse the anamnesis correctly has been shown to have a long-term negative impact on a cat's health and welfare. In conclusion, it was concluded that not checking the cervical and vaginal canal during the cesarean section with anamnesis information was as important as the examination. [ABSTRACT FROM AUTHOR]

Electrocardiography is one of the primary diagnostic methods to assess cardiac abnormalities in domestic animals including cats. Persian cats are calm pets and considered the oldest breed of cats in India which can be best suitable in apartment culture also. The present study was carried out to record the electrocardiographic parameters in 16 kittens and 16 adult cats by using the three standard bipolar limb leads (I, II, III) and augmented unipolar limb leads (aVR, aVL, aVF). Duration and amplitude of the P wave, QRS complex and T wave along with P-R and Q-T intervals were measured in lead II. The mean heart rate was 204.82±26.98 beats/ min in kittens and 183.08±14.54 beats/min in adult cats; the mean electrical axis was 102.12±22.18° in kittens and 81.41±21.08° in adult cats. Data from kittens and adults were compared and noticed the statistical difference between the R and T wave amplitude, PR interval, heart rate, and MEA. The present study documented the reference range for electrocardiography in Persian breed cats. These findings are helpful to compare the other conditions in cats at the present locality.

Feline panleukopenia is a highly contagious and often fatal disease in cats. The virus, known as feline panleukopenia virus (FPV), primarily affects kittens and unvaccinated cats. It is transmitted through contact with infected cats or their bodily fluids, as well as contaminated objects and environments. The diagnosis of FPV infection can be confirmed through a combination of clinical signs, blood tests, and fecal testing. Prevention through vaccination is recommended for all cats. This case report describes an outbreak of feline panleukopenia in a group of unvaccinated domestic cats that resulted in acute mortality. The lesions were evaluated using histopathology, and the specific viral strain was characterized using molecular techniques. The clinical course of the outbreak was peracute, with a hemorrhagic pattern and 100% of lethality. The observed clinical-pathological pattern was unusual; nevertheless, molecular studies did not highlight peculiar genomic features of the parvovirus isolate. The outbreak affected 3 out of 12 cats in a very short time. However, the prompt application of biosecurity measures and vaccination resulted in an effective interruption of virus spread. In conclusion, we could assume that the virus found the ideal conditions to infect and replicate at high titers, resulting in a particularly aggressive outbreak. [ABSTRACT FROM AUTHOR]

Although phimosis doesn't occur frequently in cats, one likely cause is sucking between orphaned kittens from the same litter. This report presents the case of a male kitten with acquired phimosis at an early age, whose main clinical signs were dysuria, pollakiuria and bulging of the foreskin. At three months of age, it was decided to perform a circumferential postioplasty to correct the defect, a procedure after which the signs remitted without complications. The aim of this report is to provide information for the resolution of similar cases. The procedure is safe and affordable. [ABSTRACT FROM AUTHOR]

Tyzzer disease (TD) is a highly fatal condition of animals caused by Clostridium piliforme and characterized pathologically by enteritis, hepatitis, myocarditis, and occasionally encephalitis. Cutaneous lesions have been reported only rarely in animals with TD, and infection of the nervous system has not been described in cats, to our knowledge. We describe here neurologic and cutaneous infection by C. piliforme in a shelter kitten with systemic manifestations of TD and coinfection with feline panleukopenia virus. Systemic lesions included necrotizing typhlocolitis, hepatitis, myocarditis, and myeloencephalitis. The cutaneous lesions consisted of intraepidermal pustular dermatitis and folliculitis, with necrosis of keratinocytes and ulceration. Clostridial bacilli were identified within the cytoplasm of keratinocytes by fluorescence in situ hybridization, and a PCR assay was positive for C. piliforme. C. piliforme can infect keratinocytes leading to cutaneous lesions in cats with the location suggesting direct contact with contaminated feces as a route of infection. [ABSTRACT FROM AUTHOR]

Kittens are prone to intestinal health problems as their intestines are not completely developed. Seaweed is rich in plant polysaccharides and bioactive substances that are highly beneficial to gut health. However, the effects of seaweed on cat gut health have not been assessed. This study compared the effects of dietary supplementation with enzymolysis seaweed powder and Saccharomyces boulardii on the intestinal health of kittens. In total, 30 Ragdoll kittens (age: 6 months; weight: 1.50 ± 0.29 kg) were assigned to three treatment groups for a 4-week feeding trial. The dietary treatment given was as follows: (1) basal diet (CON); (2) CON + enzymolysis seaweed powder (20 g/kg of feed) mixed evenly with the diet (SE); and (3) CON + Saccharomyces boulardii (2 × 1010 CFU/kg of feed) mixed evenly with the diet (SB). Compared with the CON and SB groups, dietary supplementation with the enzymolysis seaweed powder improved the immune and antioxidant capacity and also reduced the intestinal permeability and inflammation levels of kittens. The relative abundance of Bacteroidetes, Lachnospiraceae, Prevotellaceae, and Faecalibacterium in the SE group was higher than those in the CON and SB groups (p ≤ 0.05), while the relative abundance of Desulfobacterota, Sutterellaceae, and Erysipelatoclostridium in the SB group was lower than that in the SE group (p ≤ 0.05). Moreover, enzymolysis seaweed powder did not alter the level of intestinal SCFAs in kittens. Conclusively, supplementing kitten diet with enzymolysis seaweed powder can promote intestinal health by enhancing the gut barrier function and optimizing the microbiota composition. Our findings provide new perspectives on the application of enzymolysis seaweed powder. [ABSTRACT FROM AUTHOR]

Background: Tocodynamometry is an approach in small animal obstetrics to diagnose initiation, progress, completion, and problems related to parturition in queens. Aims: The present study was conducted to monitor uterine contractions using tocodynamometry at full term pregnancy and during queening and to correlate uterine contractile pattern with progression of queening. Methods: Once the signs of impending parturition were noted, the pressure transducer of tocodynamometer was placed on the lateral abdomen to monitor queening. The recordings were plotted as graph of time against pressure in mmHg. Uterine contractile patterns were assessed in order to study their relation to the progression of queening. Results: The initial uterine contractions had a baseline and peak pressures of 7-20 and 15-36.5 mmHg with mean time interval and frequency of 5.53 min and 1.91 peaks per 10 min, respectively, with mean change of amplitude of 15.35 mmHg. The progressive baseline and peak pressures of 15-32.5 and 24- 62.3 mmHg increased to 20-55 and 30-89.2, respectively, with an increase in mean frequency from 3.88 to 5.25 peaks per 10 min and increase in mean change of amplitude from 25.21 to 33.87 mmHg, followed by decrease in mean time interval from 2.82 to 1.91 min in expulsive uterine contractions. Conclusion: Monitoring uterine contractions using tocodynamometer helps in understanding progression of queening and problems that may rise during parturition. It was observed that during queening, baseline and peak pressures of uterine contractions remain the same, irrespective of presentation of kittens at birth. [ABSTRACT FROM AUTHOR]
