The cat’s claws scratched a little blood should be promptly cleaned up the wound, medical treatment and injection of rabies vaccine and immunoglobulin. 1. Clean up the wound: when scratched by the cat’s claws out a little blood, you need to promptly wash the bleeding wound with soapy water and flowing water repeatedly, and rinse the wound for more than twenty minutes, as far as possible to squeeze out the surrounding blood, to reduce the absorption of the virus on the cat’s claws, and then use saline to wash the skin wound and use sterile gauze to dry and disinfect the water. 2. Rabies vaccination: patients bleeding from cat’s claws should go to the nearby disease control center or relevant community hospitals as soon as possible within 24 hours for rabies vaccination, the earlier the vaccination, the sooner the patient’s body can produce the appropriate antibodies to avoid rabies virus infection. 3. Immunoglobulin: Because bleeding from a cat’s claw belongs to the third level of exposure to rabies, it is necessary to inject rabies immunoglobulin or anti-rabies serum around the wound to enable the body to immediately produce a large number of antibodies, thus playing a preventive role against the rabies virus.
