A 4-year-old male Canada lynx (Lynx canadensis) was referred to the ophthalmology service at the University of Saskatchewan with a 7-month history of cataract and chronic phacoclastic uveitis secondary to penetrating trauma from a lynx claw. Ophthalmic examination of the right eye revealed a corneal scar, marked aqueous flare, extensive fibrovascul...

Prairie Rattlesnakes (Crotalus viridis) are a species of conservation concern in Canada because of suspected population declines. Data on the habitat selection of Prairie Rattlesnakes at northern range limits are essential to inform management strategies and implement recovery plans in Canada and other northern regions. We used radio-telemetry and...
Article
The grasslands of southwestern Saskatchewan, Canada are home to several snake species of conservation concern at the northern extreme of their geographic range. To aid conservation assessment and management planning for these snakes, we used radio-telemetry, a geographic information system, and multivariate modeling to identify and compare macrohab...

The behaviour of snakes makes them vulnerable to road mortality, which may have conservation implications for some species. We examined factors affecting road mortality of snakes around Grasslands National Park of Canada (GNP), Saskatchewan, an area inhabited by a unique snake community within Canada, including the threatened Eastern Yellow-bellied...

Animal populations at northern range limits may use habitat differently from those at range cores, requiring distinct conservation plans. Snakes are ectotherms that often have very specific requirements, but few studies have focused on the effect of northern latitudes on habitat selection by grassland snakes. We studied movement and habitat selecti...
Article
A 4-year-old nulliparous sexually intact female chinchilla (Chinchilla lanigera) was evaluated because of a 2-month history of blood being sporadically observed in its cage. Results of physical examination of the chinchilla were unremarkable except for the presence of blood-stained fur around the perineum. There were no external lesions to account...

Two unrelated rats were presented to the Western College of Veterinary Medicine emergency service for vaginal bleeding. Each was taken to surgery due to marked blood loss and suspicion of uterine pathology. Despite similar clinical presentation, gross and histopathologic examination revealed 2 different underlying disease processes, uterine dilatat...
Article
A free-ranging coyote (Canis latrans) pup was found in rural Saskatchewan and was subsequently presented to a veterinary teaching hospital by a wildlife rehabilitator. On physical examination, the pup was found to be blind as a result of bilateral, mature cataracts, which were confirmed on postmortem examination. No other significant intraocular or...
Article
Abstract: A juvenile golden eagle (Aquila chrysaetos) was presented with proliferative epithelial lesions, consistent with avian poxvirus infection, around the eyes, on commissures of the beak, and on both feet. Despite treatment, the eagle declined clinically, and, 15 days after presentation, the eagle began seizuring and was euthanatized because...
Article
An adult, male, captive red-tailed hawk (Buteo jamaicensis) of at least 19 years of age presented in dorsal recumbency. The hawk was nonresponsive, and despite initial supportive care, died shortly after presentation. Gross postmortem revealed no abnormal findings. Histologic examination demonstrated atherosclerosis and ischemic cardiomyopathy. Thi...

An adult intact male guinea pig (Cavia porcellus) was presented with gastrointestinal stasis. Radiographic findings demonstrated a gas- and fluid-filled cecum. Treatment was initiated but the animal died shortly after presentation. Gross postmortem revealed omental torsion with vascular thrombosis and necrosis. This is the first report of omental t...

A total of 20 (14 females, six males) captive striped skunks (Mephitis mephitis) with miniature temperature dataloggers implanted free in the abdominal cavity were examined for reproductive performance and pathology because of implants. Eleven of 12 female skunks reproduced successfully 45.9+/-3.7 days after surgery to remove implanted dataloggers....
