Cat Feline Infectious Peritonitis Treatment

FIP was previously fatal in cats but antiviral treatments now offer high cure rates, representing a major advance in feline welfare.

Key Facts

FIP is caused by mutated feline coronavirus and was historically near-100% fatal
Antiviral drugs GS-441524 and remdesivir achieve remission in 80-90% of cases
Treatment courses typically last 12 weeks with close monitoring
Wet and dry forms require different dosing and monitoring approaches
Access to antivirals remains expensive and uneven globally

Welfare Considerations

The development of effective FIP treatment represents one of the most significant advances in feline medicine. Previously, FIP diagnosis was a death sentence. Improved access to antivirals and clear treatment protocols are urgent welfare priorities to prevent unnecessary suffering.
