Chronic upper respiratory disease caused by feline herpesvirus and calicivirus affects many cats, causing recurring discomfort that requires ongoing management to maintain quality of life.
Cats with chronic herpesvirus or calicivirus infections face recurring welfare challenges, particularly during stress-triggered flare-ups. During active episodes, nasal congestion impairs smell, which in turn reduces appetite and creates significant discomfort. Eye involvement can cause lasting damage if not treated promptly. Stress reduction is the most effective long-term management strategy, meaning stable home environments, consistent routines, and minimizing cat-to-cat conflict are therapeutic interventions. For cats in multi-cat households, ensuring adequate resources and escape routes reduces chronic stress load. Antiviral medications like famciclovir can shorten flare-up duration and severity in herpesvirus-positive cats.
