Cat FIP Antiviral Treatment Welfare

Antiviral drugs including GS-441524 now offer genuine hope for cats with feline infectious peritonitis, transforming a fatal diagnosis into a manageable disease.

Key Facts

GS-441524 and related nucleoside analogues achieve remission in approximately 80% of treated cats
Treatment requires 12 weeks of daily oral or injectable administration
Licensed versions (Bova, Mutian) are available in some countries; access varies internationally
Relapse can occur and some cats require retreatment or extended protocols
