What is Feline Infectious Peritonitis (FIP)?

Feline Infectious Peritonitis (FIP) is a serious viral disease caused by a mutation of feline coronavirus (FCoV). An estimated 1–2% of cats worldwide may develop FIP, and without timely treatment the condition can be fatal.

Early signs can be subtle—such as lethargy, reduced appetite, and weight loss—but the disease can progress rapidly. Early detection and prompt veterinary care are critical.

Pioneering research led by Dr. Niels Pedersen and his team at UC Davis helped demonstrate how GS-441524 can transform FIP from a fatal diagnosis into a treatable condition.

NeoFipronis® provides an officially registered, oral GS-441524 treatment designed for practical FIP care.
