Cat Herpesvirus Management: Stress Reduction and Treatment

Feline herpesvirus is a lifelong infection in most cats that causes recurrent respiratory and eye problems requiring ongoing management focused heavily on stress reduction.

Key Facts

An estimated 90% of cats have been infected with feline herpesvirus by adulthood
The virus becomes latent in nerve ganglia and reactivates during stress or immunosuppression
Classic signs include sneezing, nasal discharge, conjunctivitis and corneal ulceration
L-lysine supplementation has been widely used but evidence of efficacy is now disputed
Famciclovir antiviral tablets are effective for severe outbreaks in cats
Stress is the single most important reactivation trigger - management is preventive therapy
Multiple-cat households with social tension are a common reactivation context

Welfare Considerations

Feline herpesvirus causes chronic, recurrent disease that affects cats throughout their lives. Each flare involves respiratory discomfort, eye pain and reduced appetite that can persist for weeks. The management of stress as the primary trigger requires understanding feline social dynamics and environmental stressors that owners often do not recognise. Cats in multi-cat households with social conflict experience frequent reactivation. Cats undergoing major changes including moves, new animals or owner absence experience predictable flares. The welfare burden of poorly managed herpesvirus is substantial and largely preventable through effective stress management.

What You Can Do

Identify and reduce stress triggers in your cat environment as primary herpesvirus management
Provide sufficient litter trays, feeding stations and resting spots in multi-cat households
Use feline pheromone diffusers during predictably stressful periods such as moves
Discuss famciclovir antiviral treatment with your vet during severe flares
Maintain general health and vaccination currency to optimise immune response
Provide separate resources for all cats in multi-cat households to reduce social competition
Work with a feline behaviour specialist if multi-cat conflict is driving recurrent disease
