Feline Viral Rhinotracheitis (FVR) is a highly contagious viral infection caused by the feline herpesvirus type 1. It primarily affects the upper respiratory tract of cats, leading to symptoms such as sneezing, nasal discharge, and conjunctivitis. Kittens and unvaccinated cats are particularly vulnerable to this disease. The virus spreads through direct contact with infected cats or contaminated surfaces. While FVR can be severe, most cats recover with proper care. Vaccination is an effective way to prevent the disease, and regular veterinary check-ups can help manage any potential outbreaks in multi-cat households.
