Epidemiological investigation of euthanasia in an Ontario animal shelter.

Objectives The objective was to evaluate factors associated with euthanasia in an animal shelter in Kitchener-Waterloo, Ontario, Canada. Methods Data from 3737 cats admitted to the shelter between January and December 2011 were evaluated. Results Overall, 1989/3737 (53%) of admitted cats were euthanized. Male cats had greater odds of being euthanized than females (odds ratio [OR] 1.63, 95% confidence interval [CI] 1.29-2.05; P <0.001) and surrendered cats were more likely to be euthanized than strays (OR 38.0, 95% CI 14.8-97.69; P <0.001). Black cats were more likely to be euthanized than cats of another color (OR 1.45, 95% CI 1.16-1.80; P <0.001). Cats that spent >5 days in the shelter were more likely to be euthanized than those that spent <5 days in the shelter (OR 1.57, 95% CI 1.25-1.97; P <0.001). Cats that spent >20 days in the shelter were less likely to be euthanized than those that spent <5 days in the shelter (OR 0.26, 95% CI 0.19-0.34; P <0.001). Age, an age quadratic term, neuter status and interactions among these variables were statistically significant; the odds of unneutered animals being euthanized was high and relatively stable across age groups, but in neutered animals the odds of being euthanized increased with age before plateauing in older cats. Conclusions and relevance With >50% of the cats admitted to the shelter in 2011 euthanized, it is important to understand the contributing risk factors that predispose shelter cats to euthanasia and what changes can be made to the shelter system and in owner education to lower the incidence of euthanasia.

Dermatophyte surveillance in cats in three animal shelters in Ontario, Canada.

Objectives The aim of the study was to determine the prevalence of dermatophyte shedding in cats admitted to three Ontario animal shelters from February to May 2013. Methods Four hundred cats were sampled within 48 h of admission, using a standard toothbrush sampling technique. Dermatophyte culture was performed. Results Dermatophytes were not identified in any of the 400 cats (0-0.9% one-sided exact 97.5% confidence interval). Conclusions and relevance These results imply that dermatophyte shedding is rare in cats admitted to Ontario animal shelters. Consequently, identification of infected animals, particularly multiple animals, represents an unusual occurrence that may justify prompt and intensive control measures.
