Companion Cat Feline Herpesvirus Welfare

Feline herpesvirus (FHV-1) causes chronic respiratory and eye disease in cats - management of flares reduces welfare compromise.

Key Facts

FHV-1 establishes lifelong latent infection in virtually all cats exposed as kittens
Stress and concurrent illness trigger viral reactivation causing eye discharge, sneezing, and conjunctivitis
Recurrent corneal ulceration can lead to permanent eye damage without treatment
L-lysine supplementation was historically recommended but evidence now suggests it is ineffective
Antiviral treatment with famciclovir reduces severity of active episodes
Reducing stress triggers through environmental enrichment helps reduce flare frequency

Welfare Considerations

Chronic FHV-1 infection causes recurrent welfare compromise through eye and respiratory disease. Cats with severe FHV-1 history require proactive stress management and prompt antiviral treatment during flares. Early antiviral intervention when symptoms appear prevents progression to severe corneal ulceration.

What You Can Do

Seek prompt veterinary assessment for cats with eye discharge or recurring respiratory symptoms
Ask your vet about famciclovir treatment for FHV-1 flares rather than waiting for resolution
Minimise stress triggers including changes in routine, new animals, and rehoming
Ensure good general nutrition and vaccination to support immune competence
Avoid unproven supplements including lysine and discuss evidence-based options with your vet
