Understanding FIP in Cats: A Comprehensive Guide


What is FIP in Cat?

Feline Infectious Peritonitis (FIP) is a severe and potentially fatal viral disease in cats. It is caused by a mutation of the feline coronavirus (FCoV), a common RNA virus found in many felines. While most cats can naturally eliminate FCoV or experience no ill effects from it, the virus can mutate into FIPV in cats with weakened immune systems, leading to the development of FIP.

Causes of Weakened Immunity in Cats

Various factors can contribute to a weakened immune system in cats, often stemming from stress. Common stressors include:

  • Dirty litter boxes: Unsanitary conditions can cause stress and compromise a c's immune system.

  • Overcrowding: Cats housed in cramped spaces or experiencing social conflict may become stressed.

  • Underlying diseases: Preexisting conditions like feline leukemia or FIV can weaken immunity.

  • Travel: Long journeys can be stressful for cats.

  • Noise: Excessive noise can cause anxiety and stress.

  • Over-bathing: Frequent bathing can strip a cat's skin of natural oils and lead to stress.

It's important for cat owners to observe their pets' behaviors and identify any activities that might trigger stress to minimize these factors.

Symptoms of FIP in Cats

FIP symptoms vary depending on the type of disease, which is classified into two main categories:

Wet (Effusive) FIP

Wet FIP is characterized by the accumulation of fluid in the abdomen or chest, causing noticeable swelling. Other common symptoms include:

  • Loss of appetite: Cats may eat less or refuse food altogether.

  • Weight loss: A significant decrease in weight is often observed.

  • Lethargy: Cats become less active and playful.

  • Difficulty breathing: Fluid buildup can compress the lungs.

  • Fever: Elevated body temperature is a common symptom.

Dry (Non-Effusive) FIP

Dry FIP involves chronic inflammation in various organs throughout the body, making it harder to detect externally. It can be more dangerous than wet FIP as it can affect the nervous system, eyes, and brain. Symptoms of dry FIP include:

  • Loss of appetite and weight loss: Similar to wet FIP.

  • Lethargy: Cats become less active.

  • Fever: Elevated body temperature.

  • Ocular problems: Cloudy eyes, bloodshot eyes, or even blindness.

  • Neurological problems: Weakness in the hind legs, uncoordinated movements.

  • Seizures: In severe cases where the virus reaches the brain.

Diagnosis and Treatment

Early diagnosis and treatment are crucial for managing FIP in cats. Diagnosis involves a combination of factors, including:

  • Clinical signs and symptoms

  • Blood tests (including albumin/globulin ratio)

  • Rivalta test (for wet FIP)

  • RT-PCR (the most accurate test)

While there is no cure for FIP, treatments are available to manage the disease and improve the cat's quality of life. For more information on treatment options, refer to our guide on "Treatment Options for FIP in Cats." FIP Treatment
