Cat FHV Feline Herpesvirus Chronic Management

Feline herpesvirus (FHV-1) causes recurrent upper respiratory disease and eye problems in cats. Chronic management significantly improves quality of life.

Key Facts

FHV-1 establishes latent infection in the trigeminal nerve ganglia
Stress triggers viral recrudescence causing recurrent respiratory and ocular signs
L-lysine supplementation has been promoted but recent evidence questions its benefit
Antiviral treatment with famciclovir shows good efficacy in severe cases
Environmental stress reduction is as important as medical treatment

Welfare Considerations

Cats with chronic FHV recurrence experience repeated episodes of painful eye disease, nasal discharge, and respiratory discomfort. Stress management is a key component of treatment - reducing environmental stressors prevents recurrence as effectively as medication in many cats. Identifying and addressing stress triggers reduces frequency and severity of episodes.

What You Can Do

Identify and reduce environmental stressors for cats with frequent FHV recurrence
Discuss antiviral treatment with your vet for cats with severe recurrent FHV
Ensure FHV-positive cats are vaccinated to reduce severity of recurrence
