Cat-to-cat transmission is contagious. Feline-borne peritonitis, the full name of feline infectious peritonitis, is caused by the mutation of feline coronavirus after being infected with it. Coronavirus is a highly contagious common virus that is carried by most cats. This virus does not directly cause abdominal transmission in cats, but when the coronavirus in cats mutates and escapes from the intestines and enters other organs , it will cause cat-to-belly transmission. The main route of infection is through contact with sick cats, and healthy cats with the virus can spread the disease through their feces.

Symptoms of abdominal transmission from cats:

1. Recurrent fever. The fever will subside after taking antipyretic injections, but the fever will come back within 1-2 days.

2. Ascites, the limbs are normal, but the abdomen becomes enlarged, and it feels like there is water inside.

3. Decreased appetite and lethargy. Cats suddenly lose appetite, lose interest in daily entertainment items, and become lethargic.

4. If hens continue to squat, they may also suffer from cat-to-belly transmission.

5. Shortness of breath. The cat feels hard to breathe when going up and down stairs, or can’t breathe after exercising.

6. Eyeball lesions: cat’s eye discoloration, pupil abnormalities, jaundice and other eyeball lesions.
