Cat Feline Infectious Peritonitis Welfare Update

Feline infectious peritonitis was previously a fatal diagnosis, but antiviral drug developments have transformed outcomes with high cure rates now achievable in affected cats.

Key Facts

FIP is caused by a mutated form of the common feline coronavirus
Wet FIP with fluid accumulation and dry FIP with granulomas are the two main forms
GS-441524 antiviral treatment achieves remission in over 80% of treated cats
Treatment requires 84 days of daily injections or oral administration
Access to treatment remains limited in some countries due to licensing issues

Welfare Considerations

Previously, FIP caused inevitable deterioration and death with profound suffering. Antiviral treatment has transformed this from a terminal diagnosis to a treatable condition, representing one of the most significant recent advances in feline welfare.

What You Can Do

Consult a specialist vet immediately if FIP is suspected in your cat
Seek access to antiviral treatment through specialist veterinary practices
Advocate for full licensing of FIP antiviral treatments to improve global access
