Although congenital tracheal anomalies are not very common in veterinary medicine, they are still very important. Just as happens in human medicine, most possible variants are of very striking clinical presentation, due to the respiratory distress produced in patients. All require some type of surgical or minimally invasive correction in order to overcome the acute condition. Below is the case of a 10-month-old male feline that attended the emergency ward with acute inspiratory and expiratory dyspnea, who particularly presented marked inspiratory stridor. As a result of the patient's decease and subsequent necropsy and histopathology it was concluded that he presented segmental congenital tracheal stenosis due to absence of tracheal rings.

This essay focuses on the traditional struggle held between man and wolf and its impact over the spread of extensive cattle ranching in Campo de Calatrava. The natural ecosystem of the area, still in process of colonization during the XV and XVI Centuries, began to decline as a result of combined pressure from domestic livestock and farmers. That led to a gradual extermination of natural predators of livestock and hunting such as bears, wolves, foxen, wildcats and other wild animals considered dangerous and harmful. This type of fauna was known by the pejorative terms of «salvajinas» or vermin, and was still abundant in the early XIX Century. However, with few exceptions, this fauna disappeared from the area during the next Century. [ABSTRACT FROM AUTHOR]

The objective of this study was to objectively compare the differences in the total shape (size and pure shape) of the neurocranium between a group of domestic cat skulls (Felis catus, n=81), and wildcats (Felis silvestris, n=12) by means of geometric morphometric techniques. To achieve it, we obtained digital photographs of the left side of the skulls in a standardized form, in which 8 landmarks and 9 semilandmarks were located. After a Generalized Procrustes Superimposition, a Principal Component Analysis and a Canonical Analysis one were performed to compare and detect possible differences. Neurocranial sizes showed no differences between the two groups, however, significant differences in shape did appear. Shape changes would mainly affect the squamosal-coronal suture and, to a lesser extent, caudal skull points, therefore suggesting changes in masticatory muscles. As far as this author's knowledge, this is the first research that characterizes and compares the skull of cats using geometric morphology methods, recommending greater use of this technique given the scarcity of publications on this subject in domestic mammals.

The present article, developed within the framework of contract archeology, discloses the first in situ finding in the Lípez region of Potosí, Bolivia, of the semi-complete skeleton of an American cougar. It was discovered inside a collca, a pre-Hispanic deposit corresponding to the Late Intermediate Period (ca. 1100 years - 1450 years AD), and was associated with a Lampaya filiation vessel. An archaeozoological and taphonomic analysis revealed that it was an adult female feline of thin constitution and low weight. It was skinned for the extraction of its skin, and its meat was probably consumed as ritual food. The skeleton was placed on the floor of the structure in a left lateral decubitus position and oriented from west to east. It appears to be the final offering as part of a ceremony. According to Andean ethnohistorical, ethnographic and historical data, felines are sacred animals. Based in this worldview, this offering could symbolize fertility (due to its feminine condition), the transition from some important natural or social event that involved signs of hierarchy, power, and strength or could have been related to the moon and other important elements.

Studies about the faunistic presence of felines in Mesoamerica are extensive. As a greater number place emphasis on jaguars over any other of the five species recorded in Mexico, we identify a clear absence of adequate protocols dealing with the osteological identifications and the application of biological criteria to recognize the species represented. In this paper we present the empirical data of the felines recovered in the archaeological site of Xochicalco (660-1175 n.e.), both in bone remains and artistic representations. Three species of felines are identified: lynxes, jaguars, and pumas, with a clear predominance of the latter. The number of felines skeletons and the detailed animal behavioral portrayed on some media suggest a high level of knowledge, meaning that the animals could have been kept in captivity in Xochicalco. This hypothesis could be further analyzed along with the outcomes from the analyses carried out in other Mesoamerican sites. [ABSTRACT FROM AUTHOR]

Introduction: The urethral catheterization associated with the application of alfa-2 adrenergic agonist drug is a recent development and application technique for the collection of feline semen, with advantages over electro-ejaculation harvesting and epididymal harvesting. Objetives: Seminal collection in neotropical felines using the urethral catheterization technique. Determine the testicular and seminal parameters of samples collected by the urethral cataterization technique. Methods: The technique has been tested on Panthera onca and others small cats. In this study, individuals of Panthera onca, Puma yagouaroundi and Leopardus wiedii were used in captivity at Getulio Vargas Zoobotanical Park, Salvador, Bahia, Brazil. Medetomidine hydrochloride (0.1 mg/kg) and ketamine (5.0 mg/kg) were used as sedatives, the semen was collected by urethral catheterization. In the process were checked the testicular biometry was performed with percutaner and ultrasonography technique. The fresh samples were evaluated for conventional microscopy in the parameters of volume, sperm vigor, total motility, progressive motility, structural and functional integrity of the plasmatic membrane and sperm morphology. The samples were subjected to a freeze - thaw process using three different extenders. The thawed samples were tested using conventional microscopy, automated system analysis and flow cytometry. Results: In this study, the urethral harvest technique was successfully used in the three species. In the literature used don't have report about seminal parameters in P. yagouaroundi and urethral seminal collection in L. wiedii. The data presented describe the spermatic morphocinetics of the included species in a pioneer study. There were no differences (P > 0.05) in the seminal quality evaluating the extender, nor differences in the integrity of pre and post-freeze membranes of the samples. Conclusion: The urethral catheterization associated with the application of alfa-2 adrenergic agonist drug it's an efficient technique for semen collection in neotropical cats. The establishment of a potential association of physical characteristics with seminal quality is extremely important information on the applicability of reproductive traits in assisted reproduction programs.

Several wild species of the family Felidae are at risk, and population size is one of the most important ecological parameters to determine conservation actions. Population size is influenced by different biotic and abiotic factors that satisfy the requirements of the species to survive and reproduce, allowing the permanence of the species through time. Because population size is not homogeneous throughout the distribution, there are several hypotheses to explain their variations. One proposal considers that more abundant populations are located in regions with environmentally suitability, and population size decreases towards the less favorable ones. Another hypothesis considers that the population size is related to the internal structure of the ecological niche, where the largest populations are located in the centroid of the niche, and the size declines as the distance to this centroid increase. The objective of this study was to evaluate the relationship between population abundance, environmental suitability and ecological niche in four wild felids species of America. The density of Lynx rufus (bobcat) was correlated positively with the environmental suitability index, the highest density of Panthera onca (jaguar) was located in regions near the centroid of the niche, while the population densities of Leopardus pardalis (ocelot) and Puma concolor (cougar) did not conform to the predictions of either of the two hypotheses. The relationship between feline density and environmental characteristics was speciesspecific, with no general pattern. [ABSTRACT FROM AUTHOR]

Didelphis aurita, known as black eared oposum, is a marsupial widely distributed in South America, frequently seen in both wild and anthropogenic environments due to its great ecological plasticity. This species is commonly treated in wildlife veterinary services and has been used as alternative experimental models instead of conventional species. The aim of this report was to describe a case of double renal vein in a male, adult, specimen of D. aurita. In order to make the dissection easier, the cadaver was fixed and preserved in 10 % formaldehyde solution, and previously injected with latex in blue color by the thoracic aorta to facilitate dissection. The specimen had two right renal veins, one cranial (11.3 mm) and other caudal (10.0 mm) that drained distinctly for caudal vena cava. The left renal vein and the renal arteries were single. Although double renal vein has been reported in other species, such as dogs, cats and wild felids, this is the first mention in the genus Didelphis. The knowledge of the vascular anatomical variations is relevant for the correct execution of veterinary procedures and the interpretation of experimental findings in urogenital system research.

Metadoxine is a drug with a potential antioxidant and antifibrotic effect that is essentially used in human medicine in the treatment of acute or chronic alcoholic steatohepatitis. Numerous clinical trials and experimental investigations support its use; however, in veterinary medicine there are no field studies on this topic, although there exist isolated reports of its indication in secondary liver diseases in Latin American databases. The present study aimed to report on the prescription of metadoxine in canine and feline hepatopathies in routine practice in Colombia. Applying online web tools, a survey was conducted to establish some treatment guidelines for the use of metadoxine in the said field. Results showed that 55% of participating veterinarians prescribed metadoxine at least once in canines and felines. 74.6% of them reported a favorable evolution. As a joint therapy, dietary modifications, silymarin, and ursodeoxycholic acid were also prescribed in 80, 45.5, and 38.2% of the cases, respectively. A wide variation was detected regarding the dose, application route, frequency, and the duration of the therapeutic protocol. Regarding oral prescription, the dose was 17.3 ± 11.4 mg/dl every 12 hours. The results confirm the use of metadoxine as a treatment for hepatopathies in dogs and cats in Colombia. This highlights the need to carry out clinical trials that test the effect of metadoxine on the clinical and paraclinical evolution and prognosis of certain hepatopathies in dogs and cats.

The Felidae family, represented by 37 species, exhibits a variety of patterns on their fur: smooth coat, rosettes, streaks or spots. In this work, different aspects of the evolution, function and variations in pigmentation coat patterns of the felines are discussed. The most accepted theory of the coloration of their fur assumes that the ancestral pattern is a spotted coat. Currently, these are distributed in 22 species with blotchy, two with horizontal stripes, two vertical stripes and six have a uniform color. Also present atypical colorations as the melanism (melanin excess) characterized by a dark fur-beneficial character-, and the albinism and leucism (melanin deficiency) which present a white coat color-harmful character-. These variations that exist in color and coat patterns are stimulated by the diversity of habitat and behavior, having an important role in communication, camouflage and physiological functions of felines.

Neotropical puma (Puma concolor) diet is scarcely known, in particular that of mountain dwelling individuals from Northern South America. This is the first study on pumas from the paramo and the first puma diet analysis for Colombia. The puma diet was studied from 2007 to 2009 in the Puracé National Park in the South Colombian Andes. Paramos are unique neotropical high altitude ecosystems which store and regulate water, and are currently threatened by agricultural expansion and climate change. Seven latrines were monitored for three years and scat collected, washed and dried. Items in scat such as hair, bones, claws and others were separated. Hairs were inspected by microscopy and compared to voucher hair museum specimens. Bone fragments, claws and teeth were also compared to museum collections and identified wherever possible. Additionally, six cameras were set along game trails to document puma and potential prey presence in the area. Food items from five species were identified in 60 puma scats; Northern Pudu (Pudu mephistophiles) was the most important prey in their diet. A total of 354 camera trap-nights photographed a male and female puma, Northern pudu and Spectacled bear (Tremarctos ornatus). The main conclusion suggests a strong dependence of puma on the threatened and mysterious Northern Pudu in paramo habitats. This behavior might reflect restricted prey availability in the high Andes mountains of Colombia, and highlights the plasticity in the puma diet. Conservation actions in the paramo should thus, focus on focal wild species, and in particularly those that show a relationship, such as the one evidenced here with the dependence of puma on Northern Pudu. These findings contribute to increase the little known ecology of Andean puma populations and the species as a whole in Colombia. Baseline data on puma prey populations in different ecosystems throughout their range, is critical to understand the regional requirements for survival, and design conservation actions, to follow and evaluate the need for particular protected areas along their geographical gradients.

The domestic cat is considered the chromosomal model for the Felidae family being its 2n = 38, and FN = 72. All the chromosomal complement is distributed in somatic chromosomes with six groups (A-F), and the sex pair which is highly uniform. The E1 pair is the chromosomal marker of the family that has a secondary constriction (satellite) in the short arm. The X chromosome is similar in size and shape in all species. The banding patterns are very similar in the A1, A2, A3 pairs, B group, and the sexual pair. The chromosomal differences are greater in groups C, E and F. These modifications have occurred at expenses of acrocentric chromosomes. The present review offers an outlook of the chromosomal structure of the Felidae family in order to offer reference points for future researches on this topic. [ABSTRACT FROM AUTHOR]
