Bleeding after being scratched by a cat with a small scratch is more serious, and there is a possibility of getting rabies, which requires rabies vaccination. As long as a dog or cat scratches and bites, regardless of whether there is bleeding, as long as there are signs of scratching, it is necessary to be vaccinated. Because rabies is a lethal disease, and the death rate is 100% once rabies occurs, rabies should be preventative in nature. The saliva of cats and dogs is the main cause of rabies, so after being scratched by a cat, you need to go to the local Center for Disease Control and Prevention or a related institution to receive rabies vaccination within 24 hours. The size of the wound after being scratched by a cat is not too serious and is actively disinfected after debridement, but the awareness of vaccination must be there. The patient himself cannot be careless, although it is only prevention, but prevention is more important than treatment.
