Cat Feline Infectious Peritonitis Treatment Update

FIP was once a fatal disease in cats but antiviral treatments have transformed outcomes for affected cats.

Key Facts

Until antivirals, FIP was almost universally fatal once diagnosed
GS-441524 and similar antivirals achieve remission in 80-90% of cases
