Both cats and dogs are rabies-susceptible animals, and both may carry the rabies virus, so a cat bite that breaks the skin and bleeds a little should be evaluated for risk of rabies virus exposure. If the bite breaks the skin and there is bleeding at the same time, it is a Grade 3 exposure to rabies virus according to the Chinese Rabies Prevention Technical Guidelines. Principles of treatment for tertiary exposure: 1. Thoroughly clean and disinfect the wound, rinse it with large amounts of water under pressure for 20-30 minutes, and disinfect it with iodine povidone. 2. Go to the CDC to inject rabies immunoglobulin and rabies vaccine. 3. During the period of injection of the vaccine, the cat should be medically observed, and if the cat is still healthy and has not developed any disease after 10 days, it does not have the ability to transmit rabies when biting. 4. If the cat is still healthy and has not developed disease, the cat does not have the risk of transmitting rabies at the time of biting.
