A cat bite bleeds, in which case an injection is required. Whether it is a cat or a canine animal, saliva and teeth may contain bacteria or rabies virus. As long as the bite has a rupture in the skin or even bleeding, routine disinfection with iodophor and peroxide cleaning should be performed, and preventive injections of tetanus and rabies vaccine should be given after the skin dressing. Before vaccination, you should go to a regular hospital for detailed examination of the wound, treatment, and intramuscular injection according to the conventional principles of vaccine intramuscular injection, and also to prevent the possibility of local infection, and apply antibiotics to prevent infection if necessary. Therefore, do not have excessive fluke after being bitten and bleeding by a cat to avoid infection with rabies virus, which has a relatively high mortality rate, and there are no effective drugs and treatments to cure rabies.
