Cat Welfare and Feline Infectious Peritonitis

Feline infectious peritonitis (FIP) is a formerly fatal coronavirus disease of cats for which effective treatments now exist, transforming the welfare outlook for affected cats.

Key Facts

FIP is caused by a mutated form of feline coronavirus and was previously almost universally fatal
Antiviral treatments including GS-441524 and Remdesivir have achieved remission rates above 85% in clinical studies
Treatment costs for FIP can exceed 3,000 pounds, creating significant financial barriers for cat owners
GS-441524 was not licensed for veterinary use in the UK for several years, driving a grey market import trade
WSAVA now recognises FIP treatment protocols, and licensed treatments are becoming more available
Young cats between 6 months and 5 years are most commonly affected by FIP

Welfare Considerations

FIP treatment represents a transformative welfare advance for a disease that previously meant certain death for thousands of cats annually. The welfare implications extend beyond treatment efficacy to access - the high cost and previous licensing restrictions created significant welfare inequalities based on owner wealth. Advocacy for affordable, accessible FIP treatment is a contemporary welfare priority that has already improved thousands of cats' outcomes.

What You Can Do

If your cat is diagnosed with FIP, consult a veterinary specialist about current treatment options
Support organisations advocating for affordable FIP treatment access
Donate to feline disease research charities funding FIP treatment development
Advocate for pet insurance to cover FIP treatment costs, which are currently often excluded
Share information about FIP treatment advances within cat owner communities
