The cat is diagnosed but does not vomit or defecate. It may be that the cat’s physical constitution and resistance are relatively good, so the symptoms are mild or no symptoms appear. It may also be that the cat is in the incubation period of feline plague, so there has not yet been an outbreak. Even if the cat does not vomit or defecate, as long as it is diagnosed with feline plague, the cat must be isolated from other cats and then sent to a pet hospital for treatment in time to avoid aggravation of the condition and missing the opportunity for treatment.
