Cat Feline Herpesvirus Welfare Management

Feline herpesvirus causes recurrent upper respiratory signs and eye disease that chronic management can control to improve quality of life.

Key Facts

FHV-1 establishes latency and reactivates during stress causing recurrent respiratory illness
Ocular disease including corneal ulceration causes significant pain and impaired vision
Lysine supplementation has been shown to be ineffective despite widespread use
Antiviral medications including famciclovir reduce severity of reactivation episodes
Stress reduction prevents reactivation - a welfare benefit of stable, low-stress environments

Welfare Considerations

FHV-1 causes recurrent distress through painful eye disease and respiratory illness. Chronic management that reduces reactivation frequency through stress management and antiviral treatment significantly improves quality of life for chronically affected cats.

What You Can Do

Discuss famciclovir treatment for severe FHV-1 reactivation with your vet
Minimize stress triggers that cause herpesvirus reactivation in affected cats
Do not use lysine supplementation - evidence does not support efficacy
