Cat Feline Herpesvirus Advanced Management

Feline herpesvirus (FHV-1) causes recurrent disease throughout an infected cat's life. Long-term management strategies significantly improve welfare.

Key Facts

FHV-1 establishes lifelong latency in trigeminal ganglia after primary infection
Stress is the primary trigger for viral reactivation
Recurrent keratitis can progress to corneal scarring without treatment
L-lysine supplementation has been shown in some studies to reduce recurrence
Antiviral topical treatments (cidofovir, ganciclovir) are effective for eye disease

Welfare Considerations

Cats with recurrent FHV-1 experience repeated episodes of eye pain, nasal discharge, and malaise throughout their lives. Stress management through environmental stability and enrichment reduces recurrence frequency. When episodes do occur, prompt antiviral treatment limits corneal damage and the duration of discomfort.

What You Can Do

Implement stable routines and low-stress environments for FHV-positive cats
Seek veterinary care promptly for eye discharge in FHV-positive cats
Discuss antiviral topical treatment with your vet for recurrent keratitis
Ask your vet about L-lysine supplementation for recurrence-prone cats
