Minor bleeding from a scratch by a domesticated cat requires an injection. As soon as bleeding occurs, it is a tertiary exposure to rabies. Even a domestic cat with rabies vaccination is at risk of causing rabies virus infection and requires immediate treatment of the wound and prompt injection of tetanus and rabies vaccine. When a minor bleeding occurs after being scratched by a domestic cat, the bleeding wound should first be treated so as not to aggravate the extent of the wound. The wound can be thoroughly cleaned with running water and then disinfected with iodine or alcohol. The principle of wound exposure should be followed and the wound should not be stitched up to avoid infection or scar formation. The dose of rabies vaccination and the process of vaccination should be analyzed according to the actual situation. The current domestic rabies vaccine is based on the “5 shot method” and the “4 shot method”, with the “5 shot method” meaning one shot on the day after the cat bite, one shot on day 3, one shot on day 7, one shot on day 14 and one shot on day 28. The “5 shot method” means one injection on the day after the cat bite, one on day 3, one on day 7, one on day 14 and one on day 28; the “4 shot method” means two injections on the day after the cat bite, followed by one on day 7 and one on day 21. The rabies vaccination can be given on the same day after being scratched by a cat, and the vaccination can be given after 3, 7, 14 and 28 days. The best time to receive the rabies vaccine is within 24 hours of being scratched by a cat, and as late as possible, not more than 48 hours. In addition to the rabies vaccine, a tetanus vaccination may be required depending on the doctor’s judgment of the scratch wound.
