Cat Infectious Peritonitis: Welfare and New Treatments

How antiviral treatments for FIP are transforming outcomes for affected cats.

Key Facts

Feline infectious peritonitis (FIP) was previously considered uniformly fatal
GS-441524 and other antivirals now achieve remission in over 85% of treated cats
Treatment requires daily injections or oral dosing for 12 weeks - a welfare consideration itself
Access to treatment varies significantly by country due to licensing status

Welfare Considerations

FIP antivirals represent one of the most significant advances in feline welfare in recent decades, converting a fatal diagnosis into a manageable condition. Welfare advocacy must focus on ensuring equitable global access to these life-saving treatments.

What You Can Do

Ask your vet about FIP antiviral options if your cat is diagnosed
Support campaigns for licensing of GS-441524 in your country
Donate to charities providing FIP treatment access to cats in low-income households
