Objectives: The aim of this study was to evaluate possible risk factors for death in traumatized cats based on the clinicoepidemiological profile, the Animal Trauma Triage (ATT) scale score and the Modified Glasgow Coma Scale (MGCS) score at the time of presentation to the hospital. Methods: This was a cross-sectional study involving cats admitted to the emergency sector (ES) and the surgical clinic sector (SCS) of a veterinary teaching hospital (VTH) in northeastern Brazil over a 12-month period (2018–2019). Probable risk factors associated with non-survival after trauma were analyzed by calculating the prevalence ratio. The prediction of non-survival was evaluated by analyzing the receiver operating characteristic (ROC) curve employing the ATT scale score, MGCS score and rectal temperature. Results: In 1 year, 89 traumatized cats were admitted to the VTH, of which 90% (n = 80) were young, 54% (n = 48) were male, 79% (n = 70) were intact, 59% (n = 53) were indoor cats and 92% (n = 82) were considered as mixed breed. Blunt trauma was the most prevalent cause of injuries, reported in 76% (n = 68) of the cats. Accidents involving falls (30%; n = 27) that affected the pelvic limbs (50.6%) were the most commonly reported. The prevalence of death among cats admitted to the ES was 9.44 times higher than that of animals treated at the SCS. Trauma as result of being run over and chest trauma were associated with a higher probability of death. Most of the animals that died had a lower rectal temperature than those that survived. The ATT scale score, MGCS score and rectal temperature were predictive of mortality. Conclusions and relevance: Rectal temperature, ATT scale score and MGCS score were effective predictors of an unfavorable prognosis and point to the need for emergency procedures. Hypothermia, being run over and chest trauma were associated with a higher risk of mortality. Our findings highlight the importance of prompt and effective care for these conditions.

Objectives: We compared the effects of two alpha (α)2-adrenergic agonists on semen traits. Methods: In this study, 13 adult domestic cats were divided into two experimental groups, according to the chemical ejaculation protocol used: the first group received medetomidine hydrochloride (100 µg/kg) and ketamine (5000 µg/kg); the second group received dexmedetomidine hydrochloride (25 µg/kg) and ketamine (5000 µg/kg), both by the intramuscular route. Results: The animals responded positively (P >0.05) to chemical collection. Seminal parameters evaluated included volume, sperm vigor, total motility, progressive motility, sperm concentration, and the structural and functional integrity of the plasma membrane; sperm morphology values did not differ between groups (P >0.05). Conclusions and relevance: The results indicated that dexmedetomidine is a more viable and economical alternative to medetomidine in domestic cats submitted to semen collection by urethral catheterization. Semen collection by urethral catheterization after using α2-adrenergic agonists is a recently developed technique in feline species that is considered to be quick and highly applicable to assisted reproduction programs in felids.
