You may not necessarily develop rabies after being scratched and bleeding by a cat, but prompt rabies vaccination is recommended after being scratched and bleeding by a cat. The presence of saliva residue on the paws of cats after licking carries the possibility of carrying rabies virus. When a person is scratched by a cat, if there is obvious skin breakage and bleeding, and neither the cat nor the person has been vaccinated against rabies, the situation is more serious. Go to a vaccination station or hospital for rabies vaccination as soon as possible, rinse the wound with soapy water and flowing water alternately for more than 15 minutes, and disinfect with iodophor. If the cat has been regularly vaccinated against rabies, it is still recommended that the injured person be vaccinated. After 10 days of observation, if the cat is still healthy, the possibility of rabies infection can be basically ruled out and the subsequent vaccination may not be carried out. If the cat has not been vaccinated against rabies, the human must be vaccinated and the decision to vaccinate with anti-rabies immunoglobulin will be based on the condition of the wound. Considering that most people are scratched extensively by stray cats, and that there is almost no history of rabies vaccination for stray cats, once scratched and bleeding by a stray cat, the vaccine should be administered promptly.
