If a cat is found to have cold-like symptoms, such as cough, diarrhea, loss of appetite, listlessness, weight loss, persistent fever, etc., it may be suspected that it is transmitted through the abdomen from cats, and it should be sent to a doctor for diagnosis as soon as possible. If the cat has cloudy eyes, pus accumulation, constricted pupils, visual impairment, or symptoms such as hind limb paralysis, trembling, anemia, etc., it may be in the middle stage of feline abdominal transmission. During the onset of wet abdominal transmission, there will be a large amount of accumulation in the chest and abdomen. High protein exudate, when there is a lot of fluid accumulation, the abdomen will swell, and you can feel the fluctuation of water by touching it with your hands; this symptom is usually transmitted to the abdomen in the wet type.

Cat-to-cat transmission is not contagious to humans, but it can be contagious to other animals. Feline transmission is caused by infection with feline coronavirus, and the infection rate is very high. It is generally considered to be an infection through the mouth and nose. Cats that carry the virus will shed the virus in their feces, and the feces can infect cats who live together. A few are infected through food dishes, clothes, bedding, people or insects. Sharing cat litter, cat litter shovels, etc. may lead to infection. Generally speaking, the higher the density of cats, the higher the proportion of feline coronavirus infections. Feline coronavirus infection is particularly common in places where cats live in high-density groups, such as catteries, animal shelters, and multi-cat households.
