Companion Cat Feline Infectious Peritonitis Treatment

Recent advances in treatment of feline infectious peritonitis (FIP), a formerly fatal viral disease.

Key Facts

FIP was almost universally fatal before the development of antiviral treatments
GS-441524 and related antivirals have transformed FIP into a treatable disease
Treatment courses typically last 12 weeks with high cure rates in treated cats
Wet and dry forms of FIP respond differently to treatment protocols
Access and cost of antiviral treatment remains a barrier in some countries

Welfare Considerations

FIP causes severe progressive suffering, and the availability of effective antiviral treatment has transformed this from a welfare catastrophe to a manageable condition.

What You Can Do

Contact your vet immediately if your cat shows signs consistent with FIP
Ask about antiviral treatment options if your cat is diagnosed with FIP
Support organisations improving access to FIP treatment for all cats
