Cat Feline Infectious Peritonitis Treatment

FIP was previously fatal in virtually all cases; antiviral treatments have transformed outcomes, offering welfare hope to affected cats.

Key Facts

FIP is caused by a mutated form of feline coronavirus affecting young cats primarily
Before antiviral treatment, FIP was invariably fatal within weeks to months
GS-441524 and remdesivir-based antivirals achieve remission in over 85% of treated cats
Treatment requires 12 weeks of daily injections or oral medication
FIP is most common in cats from multi-cat environments like catteries and shelters

Welfare Considerations

FIP causes devastating suffering - neurological dysfunction, fluid accumulation, and deterioration. The availability of effective antiviral treatment is a profound welfare advance. Access to treatment remains a welfare equity issue in many countries where licensed products are expensive or unavailable.
