No, viral infectious diseases in cats are not zoonotic, do not infect humans, and do not cause any harm to human health. But it can spread to other cats because the virus can survive indoors for a long time.
Generally speaking, the initial symptoms of viral infectious diseases in cats are not obvious and are easily ignored by the owner. Once your pet cat has symptoms such as diarrhea, vomiting, fever, and fatigue, please send it to the hospital in time to find out the cause, isolate and treat it in time, and clean up the indoor environment.
