Frequently Asked Questions:

What Are the Symptoms of FIP?

Cats that have been initially exposed to FeCV usually show no obvious symptoms. Some cats may show mild upper respiratory symptoms such as sneezing, watery eyes, and nasal discharge, while others may experience mild gastrointestinal signs such as diarrhea. In most cases, these mild signs are self-limiting. Only a small percentage of cats that are exposed to the FeCV develop FIP, and this can occur weeks, months, or even years after initial exposure to FeCV.There are two main forms of FIP: effusive (wet) and non-effusive (dry). While both types are fatal, the effusive form is more common (60–70% of all cases are wet) and progresses more rapidly than the non-effusive form.Effusive (wet) FIPThe hallmark clinical sign of effusive FIP is the accumulation of fluid within the abdomen or chest, which can cause breathing difficulties. Other symptoms include lack of appetite, fever, weight loss, jaundice, and diarrhea.Non-Effusive (dry) FIPDry FIP will also present with lack of appetite, fever, jaundice, diarrhea, and weight loss, but there will not be an accumulation of fluid. Typically a cat with dry FIP will show ocular or neurologicial signs including seizures and ataxia (abnormal or uncoordinated movements). For example, the cat may develop difficulty in standing up or walking, becoming functionally paralyzed over time. Loss of vision is another possible outcome of the disease.

How to inject a FIP cat?

1. Calculate the dose before injection. Be sure to consider the remaining liquid in the syringe and needle. It is best to add 0.1ml. Increase the injection volume accordingly as the FIP cat's weight increases.

2.After filling syringe, We add a little air and make sure it's to the top of the syringe so it creates pressure to push all the fluids in.

3.First pump in the liquid, then pump in the air, then put the air behind the liquid, in front of the piston, when injecting, push in the liquid first, the air behind can push the liquid deeper.

4.If the injection site leaks, wipe off the liquid that sticks to the FIP cat's hair and skin with an alcohol pad, and you can choose to apply a hot compress with a wet towel to the injection site after 6 hours.
