Cat FIP Antiviral Treatment Welfare Revolution

New antiviral treatments for feline infectious peritonitis have transformed FIP from a fatal disease to a treatable condition.

Key Facts

FIP is caused by a mutated form of feline coronavirus causing fatal systemic inflammation
Until 2019, FIP diagnosis was effectively a death sentence in most cases
GS-441524 and related nucleoside analogues achieve remission in over 85% of treated cats
Treatment requires 12 weeks of daily injections or oral dosing with close monitoring
Licensed FIP treatments became available in Europe and the US from 2023 onwards

Welfare Considerations

The development of effective FIP antivirals is one of the most significant recent advances in feline welfare. Previously diagnosed cats faced euthanasia as the only compassionate option. Treated cats experience rapid clinical improvement and most achieve long-term remission. Access to treatment is the primary remaining welfare barrier given cost.
