Not sure FIP ?Don't panic. Let's figure it out together
Symptoms of Feline Infectious Peritonitis (FIP) It may take several weeks to months for cats to show symptoms of FIP. The initial signs of FIP can range from depression to changes in appetite to fever.
- Color Change: Iris changes color (often to a muddy brown). - Cloudiness: Looks like there is "fog" or sediment inside the eye. - Pupil Irregularity: Pupils are different sizes (Anisocoria). - Vision Loss: Bumping into objects.
Neuro FIP(Brain/Nerve Form)
- Ataxia: Wobbly walking, loss of balance, walking like "drunk". - Seizures: Sudden convulsions or tremors. - Head Tilt: Holding head to one side constantly. - Paralysis: Dragging hind legs or inability to jump.
Neurological or ocular symptoms are commonly associated with advanced FIP progression.In these cases, time matters. Delaying treatment decisions may significantly impact outcomes.
Feline Infectious Peritonitis (FIP) is a serious viral disease caused by a mutation of feline coronavirus (FCoV).With modern antiviral treatment, FIP is no longer considered a fatal disease.
No. FIP itself is not contagious.While feline coronavirus can spread between cats, the mutated virus that causes FIP does not.
FIP is more commonly seen in: - Kittens and young cats - Cats in shelters or multi-cat households - Cats under stress or with weakened immunity Most cats exposed to coronavirus never develop FIP.
Common signs include: - Persistent fever - Loss of appetite and weight loss - Lethargy - Abdominal or chest fluid (wet FIP) - Neurological or eye symptoms (dry FIP) Symptoms vary by cat and disease type.
There is no single definitive test for FIP. Diagnosis is based on: - Clinical signs - Bloodwork (such as A/G ratio) - Imaging or fluid analysis
Standard treatment lasts 84 days (12 weeks). Cats that complete the full course and remain stable afterward are considered cured.
Both forms are effective when correctly dosed. - Maxpaw injectable GS-441524 typically shows improvement within 1–3 days and is recommended for early-stage or severe cases. - Maxpaw oral tablets usually show improvement within about 7 days, and are suitable once the cat is stable and eating well.
When properly dosed and completed, success rates can reach 95–98%.When properly dosed and completed, Maxpaw treatment achieves up to 98% success.
Relapse rates are low (below 5%). Most relapses can be successfully treated with a second course.
