Prevalence of feline chronic gingivostomatitis in feral cats and its risk factors.

Abstract

OBJECTIVES: This study investigated the prevalence of feline chronic gingivostomatitis in urban feral cats in South Korea and analysed its risk factors. METHODS: Three hundred and forty-five feral cats that visited the hospital for neutering using a trap-neuter-return approach were screened for feline chronic gingivostomatitis based on clinical criteria. In addition, we determined if body weight, sex and the presence of tongue lesions are risk factors for feline chronic gingivostomatitis. The difference in severity due to the presence or absence of risk factors, and the relationship between gross findings and histopathological lesions, were analysed by grading lesion severity. RESULTS: Feline chronic gingivostomatitis was diagnosed in 92 cats. Disease prevalence did not significantly differ with body weight and sex but was significantly related to tongue lesions. CONCLUSIONS AND RELEVANCE: The prevalence of feline chronic gingivostomatitis in urban feral cats in South Korea was 26.6%. It was significantly more prevalent in cats that had tongue lesions. Severity was also significantly associated with tongue lesions. Feline chronic gingivostomatitis may be associated with an infectious agent that causes tongue lesions.
