Companion Cat Infectious Peritonitis Treatment Advances

Effective antiviral treatment for feline infectious peritonitis (FIP) has transformed the welfare outlook for affected cats since 2019.

Key Facts

FIP was previously considered invariably fatal in affected cats
Antiviral drugs including GS-441524 and remdesivir achieve cure in 85-90% of cases
Treatment requires 12 weeks of daily medication and careful monitoring
Access and cost of treatment remain barriers for some owners despite improving availability

Welfare Considerations

FIP antivirals have transformed a universally fatal diagnosis into a largely curable disease. Cats that would previously have been euthanised or died painfully now recover. Improving access to treatment and reducing barriers ensures more cats benefit from this welfare transforming advance.

What You Can Do

Consult your vet immediately if FIP is suspected in your cat
Research current licensed and unlicensed antiviral options with your veterinarian
Support campaigns for improved access to FIP antivirals at reduced cost
