Cat plague is not contagious to humans. However, it is easily transmitted to other healthy cats, so cats with feline distemper should be isolated as soon as possible and then treated. Special attention should be paid to the fact that cats have very strong tolerance and are not easily discovered by their owners in the early stages of being infected with feline plague. However, cats will also show some abnormal behavioral states, such as: fever, listlessness, sudden high fever, stubborn vomiting, diarrhea, dehydration, etc. Owners need to pay attention to the daily behavior of cats.
