FIP Cat Treatment: The Life-Saving Information

I. Introduction

Feline Infectious Peritonitis (FIP) is a complex and often misunderstood disease that affects cats. We’ve seen firsthand the confusion and distress it can cause among cat owners. This article aims to shed light on FIP and its treatment, providing comprehensive information that you may not always receive from your vet. It’s a journey of understanding, a journey of hope, and a journey of love for our feline friends.

II. Understanding FIP in Cats

What is FIP?

FIP is a viral disease caused by certain strains of the feline coronavirus. It’s an aggressive disease that can affect cats of all ages, but it’s more common in young cats and kittens. The virus can mutate in the cat’s body, leading to an immune response that results in inflammation in various parts of the body. This inflammation can cause a wide range of symptoms and complications, making FIP a serious and often fatal disease.

Types of FIP

FIP can manifest in three forms: wet (effusive), dry (non-effusive) and neuro/ocular FIP

  • Wet FIP is characterized by the accumulation of fluid in the abdomen or chest, leading to breathing difficulties and a distended abdomen.
  • Dry FIP involves granulomas—small collections of inflammatory cells—in various organs. These granulomas can interfere with the function of the affected organs, leading to a wide range of symptoms.
  • There’s also a form that affects the brain and nervous system, known as neurological FIP, which can cause neurological symptoms such as seizures and loss of coordination.

Symptoms of FIP

Symptoms of FIP can vary widely and may include fever, weight loss, loss of appetite, and lethargy. Wet FIP often causes a distended abdomen due to fluid accumulation, while dry FIP symptoms depend on the organs affected. For instance, if the liver is affected, the cat may become jaundiced, while lung involvement may cause breathing difficulties. Neurological FIP can lead to changes in behavior, seizures, and loss of coordination. It’s important to remember that these symptoms can also be seen in many other diseases, which is why FIP can be difficult to diagnose.

III. The Diagnosis Process

Challenging to Diagnose FIP

Diagnosing FIP can be challenging due to its nonspecific symptoms. Vets often rely on a combination of clinical signs, blood tests, and analysis of any accumulated fluid. For instance, a blood test may reveal anemia and increased proteins in the blood, while analysis of the fluid from wet FIP may show high protein levels and specific types of cells. However, these findings are not exclusive to FIP and can be seen in other diseases as well.

FIP is often misdiagnosed because its symptoms can mimic other diseases. I remember a case where a cat was initially diagnosed with liver disease due to jaundice and weight loss. However, further testing revealed it was actually suffering from dry FIP. This highlights the importance of comprehensive diagnostic testing in ensuring an accurate diagnosis.

The Importance of a Second Opinion

Given the complexities of diagnosing FIP, it’s crucial to seek a second opinion if your cat’s condition doesn’t improve or worsens despite treatment. A second opinion can provide a fresh perspective and may uncover aspects of the case that were initially overlooked. It’s always better to have more information when dealing with a disease as complex as FIP.

IV. Treatment Options for FIP

Traditional Treatment Options

Traditional treatment for FIP is mainly supportive and includes fluid therapy to address dehydration and anti-inflammatory drugs to control inflammation and fever. Fluid therapy can help replace the fluids lost due to vomiting, diarrhea, or lack of appetite, while anti-inflammatory drugs can help reduce the inflammation caused by the disease. However, these treatments do not address the underlying cause of the disease and are mainly aimed at improving the cat’s quality of life.


A 2018 study published by Murphy et al. demonstrated that GS-441524, a less chemically complex parent nucleoside (also patented by Gilead), was highly effective against experimentally induced FIP at a dosage of 4.0 mg/kg subcutaneously every 24 h for 12 weeks (84 days) in 10 laboratory cats. This gives us hope to treat FIP cats.

Experimental Treatments and Clinical Trials

There are ongoing clinical trials exploring new treatments for FIP. Participating in these trials can provide access to cutting-edge treatments and contribute to our understanding of the disease. I’ve had patients who have participated in these trials, and while it’s not a guarantee of a cure, it does offer hope for a potential breakthrough in FIP treatment.

V. What Vets Don’t Often Tell You

The Reality of FIP Prognosis

FIP is often considered fatal, but it’s important to remember that every cat is unique, and some do respond well to treatment. I’ve seen cases where cats with FIP have lived for months or even years with a good quality of life. While it’s important to be realistic about the prognosis, it’s equally important to maintain hope and celebrate every moment with your beloved pet.

The Cost of FIP Treatment

The cost of GS-441524 formulation to treat Feline Infectious Peritonitis cats can vary widely depending on several factors.

  • Dosage and Treatment Duration: The cost of GS-441524 is often calculated based on the required dosage and the duration of treatment. Cats with FIP may require treatment for several weeks or even months. The longer the treatment duration and the higher the dosage, the more expensive the treatment can be.
  • Concentration of the Medication: GS-441524 may be available in different concentrations, and the cost can vary depending on the concentration used. Higher concentrations may be more expensive but can also allow for smaller volumes to be administered.
  • Source of the Medication: The source from which you obtain GS-441524 can impact the cost. Some cat owners obtain the medication through compounding pharmacies, while others may participate in clinical trials where the medication is provided as part of the study. The cost can also vary if you purchase it from a trusted online source.

FIP Doctor provides a website to calculate daily and monthly dosage and cost based on the type of FIP and weight.

The Emotional Toll of FIP

Dealing with a cat’s FIP diagnosis can be emotionally draining. I’ve seen many owners struggle with feelings of guilt, sadness, and anxiety. It’s crucial to seek support from friends, family, or professional counselors during this time. Remember, it’s okay to feel overwhelmed and it’s okay to ask for help. You’re not alone in this journey.

VI. Caring for a Cat with FIP at Home

Managing Symptoms at Home

Making your cat comfortable at home involves managing their symptoms. This can include providing a warm and quiet place to rest, encouraging them to eat, and giving them plenty of love and attention. I’ve had clients who’ve set up special areas in their homes for their cats, complete with heated beds and favorite toys. These small gestures can make a big difference in your cat’s comfort and well-being.

Dietary Considerations

Cats with FIP often lose their appetite, so it’s important to offer them palatable, high-quality food. Warming up their food or offering a variety can sometimes help stimulate their appetite. I’ve had clients who’ve had success with feeding their cats homemade meals, under the guidance of a veterinary nutritionist. It’s all about finding what works for your cat and providing them with the nutrition they need.

Regular Vet Check-ups and Early Detection

Regular vet check-ups can help detect any health issues early, including FIP. Early detection can lead to more effective management of the disease. I’ve had cases where early detection of FIP has allowed for early intervention and improved outcomes. It’s a testament to the importance of regular vet visits and proactive healthcare.

Preventing the Spread of FIP

In multi-cat households, it’s important to isolate a cat diagnosed with FIP to prevent the spread of the virus. Regular cleaning and disinfection are also crucial. I’ve had clients who’ve successfully managed to prevent the spread of FIP in their multi-cat households through diligent hygiene practices and careful management. It’s a challenging task, but it’s certainly possible with the right measures.

VII. Conclusion

Understanding FIP and its treatment can be a complex journey, but remember, you’re not alone. Stay informed, ask questions, and don’t lose hope. Feel free to reach out with any questions or share your experiences—we’re all in this together. And remember, every moment with your beloved pet is precious. Cherish them, love them, and know that you’re doing your best for them.

Remember, this article is intended to provide general information about FIP and its treatment. Always consult with your vet for advice tailored to your cat’s specific situation.
