FIP is a complex, fatal viral disease caused by a mutation of the common Feline Coronavirus. The mutation allows the virus to invade white blood cells, causing severe systemic inflammation. It comes in "Wet" (effusive) and "Dry" (granulomatous) forms.
This condition requires veterinary attention.
If your animal shows the Key or Common signs listed, please visit a clinic immediately. This is a life-threatening emergency.
Report Case / Get HelpWhile the benign coronavirus is highly contagious effectively via feces, the *mutated* FIP virus is essentially not contagious from cat to cat. Each FIP case is an individual mutation event.
Wet FIP involves fluid accumulation in the chest or abdomen (pot-bellied appearance). Dry FIP causes inflammatory masses on organs (kidneys, brain, eyes). Both lead to failure to thrive and death.
Diagnosis is notoriously difficult. Analyze fluid if present (straw-colored, high protein). The Rivalta test is a screening tool. PCR and biopsy provide definitive confirmation.
Historically fatal. New antiviral treatments (GS-441524) have shown curative potential but are strictly regulated or expensive. Palliative care focuses on comfort.
Minimizing stress and overcrowding in shelters reduces the viral load and mutation risk. There is no effective vaccine.
Without new antiviral therapy, mortality is ~100%. With treatment, cure rates are rising significantly.
