A cat that poops black and sticky may be in the early stage of feline plague. If it has already started to have watery or bloody stools, it may be in the late stage of feline plague. Feline distemper is a relatively common disease and cannot be judged just by the color of the feces. It is best to go to a pet hospital or prepare special test strips for testing. When it is determined that a cat is infected with feline distemper, it should be isolated from other cats in time and taken to a pet hospital for professional treatment, which will help the cat recover to health.
