Feline coronavirus positivity depends on the specific disease. The first is an intestinally transmitted disease in cats caused by feline enteric coronavirus. The mortality rate is generally low.

A cat's coronavirus positivity depends on the specific disease it suffers from. There are two main types of diseases caused by feline coronavirus. The first is an intestinally transmitted disease in cats caused by feline enteric coronavirus, which mainly causes enteritis in young kittens. The second is feline infectious peritonitis caused by feline coronavirus mutations.

The symptoms of feline intestinal coronavirus disease include elevated body temperature, decreased appetite, vomiting, accelerated intestinal motility, moderate diarrhea, and anal swelling. In more severe cases, cats may become dehydrated. Mortality rates are generally low.

The initial symptoms of feline infectious peritonitis are not obvious, but may include loss of appetite, poor energy, weight loss, persistent fever and other symptoms. Later symptoms will be clearly divided into dry and wet types.

Wet type feline infectious peritonitis, most infected cats will die within two months. There is high protein exudate in the chest and abdomen. The more pleural effusion, the more difficult it is to breathe. Dry feline infectious peritonitis can cause pyogranulomatous lesions of organs. Cats will become thin, have cloudy eyes, develop visual impairment, etc. Feline infectious peritonitis has a 95% fatality rate.
