Causes
Feline herpesvirus and/or calicivirus. Highly contagious through secretions. Once a cat is infected, herpesvirus stays for life and can reactivate with stress.
Diagnosis
Clinical diagnosis. In complicated cases, specific tests to identify the virus.
Treatment
Supportive care: hydration, cleaning the eyes and nose, stimulating the appetite (tasty, warmed food), and antivirals in severe cases. Relapses are linked to stress.
Prevention
VACCINATION (it is part of the feline trivalent CORE vaccine). Reducing stress and good hygiene in multi-cat households.
