Cat FHV Feline Herpesvirus Management

Feline herpesvirus causes recurrent upper respiratory infections and eye disease throughout a cat's life once infected.

Key Facts

An estimated 80-90% of cats are infected with FHV-1 during their lifetime
Stress is the most common trigger for viral reactivation and recurrent disease signs
Antiviral treatment with famciclovir reduces recurrence severity and frequency
Environmental management to reduce stress decreases reactivation frequency
FHV causes conjunctivitis and corneal ulcers that can cause permanent eye damage

Welfare Considerations

FHV infection is effectively lifelong and causes repeated episodes of respiratory and eye disease. Stress management to reduce reactivation, antiviral treatment during active disease and appropriate supportive care significantly reduce the welfare burden.

What You Can Do

Work with your vet to develop a stress reduction plan for cats with FHV-related disease
Discuss antiviral treatment options for cats with frequent severe FHV reactivations
Monitor for corneal ulcers during FHV flares and seek prompt treatment to prevent scarring
