Feline Infectious Peritonitis (FIP) - Symptoms, Diagnosis & New Treatments
Explore FIP symptoms, diagnosis methods, and breakthrough antiviral treatments now available.
What is Feline Infectious Peritonitis (FIP)?
Feline Infectious Peritonitis (FIP) is a fatal disease caused by coronavirus mutation. Previously nearly 100% fatal after diagnosis, new medications now offer treatment possibilities.

FIP Development Mechanism
FIP develops when feline coronavirus (FCoV) mutates inside a cat's body. Not all infected cats develop FIP. Weak immunity and stress trigger the disease development.
Types of FIP
- Wet FIP: Fluid accumulation in abdomen or chest. Rapid progression.
- Dry FIP: Granuloma formation affecting organs. Slow progression, neurological symptoms possible.
Diagnosis
No definitive test exists. Clinical symptoms, coronavirus titers, peritoneal fluid analysis, and tissue biopsy are considered. CSF analysis is done if neurological symptoms present.
New Treatments
Latest treatments use GS-441524 (the active metabolite of Remdesivir)-based antivirals. Some cats achieved long-term survival. Treatment typically lasts 12+ weeks; neurological or ocular forms may require longer treatment.
