Feline Herpesvirus is one of the most common causes of upper respiratory infections in cats, especially in shelters or multi-cat homes. It presents with sneezing, eye discharge, nasal congestion, and sometimes ulcers on the eyes. Once infected, cats carry the virus for life, with flare-ups during stress.
Management focuses on supportive care—hydration, nutrition, and sometimes antivirals. Stress reduction is key, especially in rescue environments, as flare-ups are often triggered by environmental changes.
