Cat FIP Treatment Revolution: Welfare Impact

The recent availability of effective antiviral treatments for feline infectious peritonitis (FIP) represents one of the most significant advances in companion animal welfare in decades.

Key Facts

FIP was historically fatal in virtually all diagnosed cats, caused by a mutant form of feline coronavirus
GS-441524 and remdesivir-based antivirals achieve remission rates of over 80% in FIP-affected cats
Treatment courses typically last 84 days and require daily injections or oral medication
FIP treatment has transformed from a death sentence to a manageable disease for most affected cats
Access to licensed FIP treatment varies globally, with some regions relying on unlicensed compounded products

Welfare Considerations

The development of effective FIP treatment is an extraordinary welfare advance. Before 2019, a diagnosis of FIP was effectively a death sentence causing profound suffering in young cats through effusion, organ failure and neurological dysfunction. Antiviral treatment allows the large majority of cats to recover fully and live normal lives. The welfare benefit - measured in years of good-quality life for thousands of cats annually - is enormous. Access to affordable treatment globally remains a welfare equity challenge.
