Companion Cat FIP Treatment Access 2026

Update on global access to antiviral FIP treatments following the breakthrough in feline infectious peritonitis therapy.

Treatment requires 84 days of daily medication at significant cost
Generics have reduced cost substantially but regulatory approval varies by country
Access remains limited in lower income countries where the disease is common
Treatment success rates exceed 85% in cats that complete the full course

Welfare Considerations

FIP previously caused certain, painful death for affected cats. The availability of effective antivirals has transformed this from a welfare catastrophe into a manageable condition. Ensuring equitable access to these treatments globally is now the key welfare challenge.
