Feline viral rhinotracheitis (FVR) is a highly contagious respiratory disease in cats caused by the feline herpesvirus. It primarily affects the upper respiratory tract, leading to symptoms such as sneezing, nasal discharge, and conjunctivitis. Kittens and unvaccinated cats are particularly vulnerable to this infection. 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 it is often included in routine feline vaccinations to protect against multiple illnesses.
