Cats as young as one and a half years old may suffer from abdominal transmission. Feline infectious peritonitis is a cat infected with feline coronavirus. It is now generally believed to be an oronasal infection. Cats carrying the pathogen will excrete the pathogen in their feces, and cats living together will be infected through this. This virus is very fragile and can be killed by ordinary disinfectants. It usually infects adult cats under 4 years old.

Feline-transmitted peritonitis is caused by cats infected with feline coronavirus, and the mortality rate is very high. It is generally divided into wet peritonitis and dry peritonitis. Generally speaking, the cure rate of feline infectious peritonitis is relatively small, but it is not 100% fatal. The owner can consider treating the cat.
