Peritonitis Treatment in FIP Cats

Updated: Mar 17

Feline Infectious Peritonitis (FIP) is a devastating and often fatal disease that primarily affects cats. It's essential for cat owners and veterinarians to understand this disease's causes, symptoms, and available treatments. In this article, we will delve into the scientific aspects of FIP, explore peritonitis treatment options, and discuss how to manage this challenging condition.

Understanding FIP in Cats

The Scientific Name: Feline Panleukopenia Virus

FIP is caused by the Feline Coronavirus (FCoV), which is closely related to the Feline Panleukopenia Virus (FPV). FPV is scientifically known as Feline Panleukopenia Virus and is a part of the Parvoviridae family. Understanding this relationship is crucial because FCoV can mutate into a more virulent form, leading to FIP.

What Exactly is FIP?

FIP, or Feline Infectious Peritonitis, is a severe, progressive disease that primarily affects young cats. It occurs when a mutation of the FCoV attacks and infects susceptible cats. This virus primarily targets white blood cells in the host's body, leading to a drop in their numbers, a condition known as panleukopenia.

FIP Symptoms and Diagnosis

Understanding FIP is challenging due to its varied clinical presentations. The disease can manifest in four main forms:

Wet FIP:

This form is characterized by the accumulation of fluid in the abdominal and chest cavities. Symptoms include weight loss, abdominal pain, and difficulty breathing. Wet FIP is often diagnosed through clinical signs and laboratory tests.

Dry FIP:

Also known as the granulomatous form, dry FIP leads to the formation of inflammatory masses in various organs, including the liver, kidneys, and intestines. This form is harder to diagnose and may require more extensive testing.

Ocular FIP:

Ocular FIP, or Feline Infectious Peritonitis with ocular involvement, is one of the various clinical forms of FIP that affects cats. In this form, the disease primarily manifests in the eyes, leading to a range of ocular symptoms. These can include uveitis (inflammation of the uvea, which includes the iris), eye discharge, squinting, cloudiness of the cornea, and even blindness in severe cases. Ocular FIP often occurs concurrently with other forms of the disease, such as wet or dry FIP, making diagnosis and treatment particularly challenging.

Neurological FIP:

Neurological FIP, a rare and severe form of Feline Infectious Peritonitis (FIP), affects a cat's central nervous system. This devastating variant of the disease occurs when the FIP virus invades the brain and spinal cord, leading to neurological symptoms. Cats with neurological FIP may exhibit a wide range of signs, including seizures, disorientation, paralysis, behavioral changes, and loss of coordination. Unfortunately, neurological FIP is often challenging to diagnose and treat effectively. The prognosis for cats with this form of the disease is typically poor, and treatment options are limited. Managing the symptoms and providing supportive care to maintain the cat's comfort and quality of life is the primary approach. Neurological FIP underscores the importance of early FIP detection and prevention efforts to protect feline companions from this devastating condition.


To diagnose FIP, veterinarians often consider clinical signs, blood tests, and tissue samples. The Polymerase Chain Reaction (PCR) test is commonly used to detect the virus in a cat's body. However, FIP can be challenging to diagnose definitively, and sometimes a post-mortem examination is required for confirmation.

Peritonitis Treatment in FIP Cats: An Uphill Battle

Treating FIP is a complex and often challenging task. The disease is curable and there are approaches to manage its symptoms. It's essential to work closely with a veterinarian to provide the best possible care for your FIP-affected cat.

Supportive Care

Supportive care is a cornerstone of managing FIP. Supportive care measures include:

Pain Management: Pain relief medications can help alleviate discomfort.

Fluid Therapy: Administering fluids can help with dehydration caused by fever and loss of appetite.

Nutritional Support: Cats with FIP often lose their appetite. Nutritional supplements or syringe feeding may be necessary to maintain their weight.

Antiviral Drugs: GS-441524 antiviral drug is successful in managing FIP. However, duration can vary from cat to cat.

GS-441524: The FIP Cure

GS-441524 is an antiviral drug with similarities to Remdesivir, an antiviral drug used in humans. It has gained attention in the treatment of FIP in cats. The drug can inhibit viral replication and potentially extend the lifespan of FIP-affected cats. However, it's essential to use GS-441524 under veterinary supervision, as the dosage must be precise, and rare side effects may occur.

The Dose Calculator

Administering GS-441524 to a FIP cat requires precision. The FIP dosage calculator can be a valuable tool for veterinarians and cat owners. It helps determine the correct dosage based on the cat's weight and the concentration of the drug. Ensuring accurate dosing is critical to maximize the drug's potential benefits while minimizing side effects.
