What Is FIP? Feline Infectious Peritonitis (FIP) is a severe and often fatal viral disease in cats caused by a mutation of the feline coronavirus.
This illness primarily affects cats’ immune systems, leading to inflammation in the abdomen, chest, or other organs.
Understanding FIP is crucial for cat owners, as early detection and management can significantly impact a cat’s quality of life.
Understanding FIP: Causes and Transmission
Feline Infectious Peritonitis (FIP) is caused by a mutation of the feline enteric coronavirus (FECV), a common virus among cats.
While many cats may carry this mild coronavirus without issue, only a small percentage experience a mutation that leads to FIP, where the virus attacks white blood cells, triggering widespread inflammation.
Factors like genetics, stress, and the immune system may influence whether the virus mutates, though the exact cause remains unclear.
FIP itself is not contagious, but the coronavirus that can mutate into FIP spreads easily through saliva, feces, and close contact, particularly in multi-cat environments like shelters and catteries.
Preventative measures include maintaining clean litter boxes, reducing stress, and practicing good hygiene in multi-cat households.
Veterinarian Dr. Lisa Davis explains, “While exposure to feline coronavirus is common, FIP remains a rare outcome. It’s crucial for cat owners to monitor their pets for early signs of illness, especially in multi-cat environments.”
Symptoms of FIP
FIP can present in two forms: the wet (effusive) form and the dry (non-effusive) form. Both forms share some common symptoms but also exhibit unique characteristics. Symptoms can vary greatly depending on the form and which organs are affected.
- Loss of Appetite and Weight Loss: Cats affected by FIP often experience a noticeable decline in appetite, leading to significant and sometimes rapid weight loss. This symptom is a key indicator of the disease’s impact on the cat’s overall health and energy levels.
- Fever Unresponsive to Antibiotics: A persistent fever is a common sign of FIP, and it often does not respond to conventional antibiotic treatments. This unresponsiveness is due to the viral nature of the illness, as antibiotics are ineffective against viruses.
- Lethargy: Cats with FIP may become unusually tired, inactive, or disinterested in their usual activities. Lethargy is a reflection of the toll the disease takes on the body, often leaving the cat with little energy to engage with its surroundings.
- Jaundice: In some cases, FIP can cause jaundice, a yellowing of the skin, gums, and eyes. This occurs when the liver is affected, leading to an accumulation of bilirubin in the blood, a pigment that turns tissues yellow.
- Wet Form Symptoms: This form is characterized by fluid accumulation in the abdomen or chest, leading to swelling or difficulty breathing. It progresses rapidly and is often fatal.
- Dry Form Symptoms: The dry form affects specific organs like the liver, kidneys, or eyes, causing inflammation without fluid buildup. Neurological symptoms, such as seizures or difficulty walking, may also occur.
Wet vs. Dry FIP: Key Differences
The wet form of FIP is often easier to diagnose due to the visible symptoms like abdominal swelling or labored breathing caused by fluid buildup.
The dry form, however, can be more challenging to detect as it involves inflammation of organs, making it crucial to observe any behavioral changes or symptoms.
Blood tests, ultrasound, and fluid analysis from the affected areas are common diagnostic methods. Unfortunately, definitive diagnosis often requires examining tissues affected by the inflammation.
According to Dr. Emily Fox, a feline specialist, “Identifying FIP early can be difficult, especially with the dry form. Pet owners should be vigilant in monitoring any behavioral changes or unexplained symptoms and seek veterinary care promptly.”
Treatment Options for FIP
Treatment for FIP, once considered a fatal disease, has seen significant advances, particularly with the development of antiviral drugs like GS-441524, which have dramatically improved survival rates.
However, these treatments can be costly and may not be accessible everywhere.
Supportive care, including fluid therapy, appetite stimulants, and anti-inflammatory medications, plays a crucial role in managing symptoms and enhancing a cat’s quality of life.
In some cases, experimental therapies may be explored to slow the disease’s progression.
Ongoing monitoring through regular vet visits, blood tests, and imaging is essential to adjust treatments and ensure the best outcome for cats undergoing treatment.
Veterinarian Dr. Alice Green states, “Although FIP remains a challenging disease, innovative antiviral treatments are providing a lifeline for affected cats. Close monitoring and swift intervention are key in managing FIP effectively.”

Preventing FIP in Cats
Preventing FIP in cats focuses on reducing exposure to the feline coronavirus, particularly in multi-cat environments.
While eliminating the virus entirely is challenging, maintaining good hygiene, minimizing stress, and avoiding overcrowding are key measures.
Though there is no universally effective vaccine for FIP yet, ongoing research holds promise.
Cat owners should also prioritize clean litter boxes, a low-stress environment, and provide individual resources like food bowls and beds to lower the chances of the virus spreading or mutating into FIP.
Dr. Jessica Brooks advises, “Preventive measures and maintaining a hygienic environment are critical for reducing the risk of FIP in multi-cat households. Owners must be proactive, especially in shelter or cattery settings.”
Early Detection and Proactive Care
According to the Cornell Feline Health Center, FIP is a complex and often misunderstood feline disease, making early detection crucial.
While there is no definitive cure, antiviral treatments are showing promise, and regular monitoring of symptoms is essential.

Similarly, WebMD for Pets emphasizes the importance of early diagnosis and the use of supportive care alongside antiviral therapies to manage FIP effectively.
Both sources encourage cat owners to stay informed about the disease and work closely with veterinarians to ensure proactive care.

Conclusion
FIP is a complex and often devastating disease for cats, but understanding its causes, symptoms, and potential treatments can help pet owners navigate this challenging situation.
By staying informed, maintaining hygiene, and working closely with veterinarians, cat owners can improve their pets’ chances of managing this illness effectively.
FAQs
1. Is FIP contagious between cats?
FIP itself is not contagious, but the feline coronavirus, which may mutate into FIP, can spread between cats through saliva and feces.
2. What are the early symptoms of FIP?
Common early signs include fever, lethargy, weight loss, and loss of appetite. In the wet form, abdominal swelling may occur, while the dry form may show neurological signs.
3. Can FIP be cured?
There is no definitive cure for FIP, but antiviral drugs, such as GS-441524, have shown promise in extending the lives of cats with FIP.
4. How is FIP diagnosed?
Diagnosis usually involves blood tests, ultrasound imaging, and analysis of fluid samples. In some cases, tissue biopsies may be needed for a definitive diagnosis.
5. How can I reduce the risk of FIP in my multi-cat household?
Maintaining cleanliness, minimizing stress, and reducing overcrowding can help prevent the spread of feline coronavirus, which may mutate into FIP. Providing separate resources and clean litter boxes for each cat is also important.
6. Is there a vaccine for FIP?
While some vaccines exist, they are not universally effective, and research is ongoing. Currently, prevention focuses on hygiene and minimizing stress and exposure.
