Sometimes I feel that the injury is not very serious, so I don't pay attention, which causes the wound to become inflamed and infected, and even be infected with some serious or fatal diseases, such as rabies. Therefore, after being scratched or bitten by a cat or dog, it must not be taken lightly and must be dealt with immediately. If bitten by a dog, immediately rinse the injured dog's saliva with soap and plenty of water, and then carefully disinfect the wound and surrounding area with hydrogen peroxide or iodine. If the dog is in your own home and is regularly vaccinated every year, you only need to pay attention to applying medicine to the wound. If it is a dog outside or without anti-epidemic measures, the injured person must be sent to the hospital for diagnosis and treatment, and injected with rabies vaccine. Generally speaking, cats rarely bite people, and there is a greater chance of being scratched by cats. If you are caught by a cat, you should not ignore the small scratches. You should also wash them with soap and water first, and then carefully disinfect them with hydrogen peroxide and iodine. In case of being bitten by a cat, especially by a stray cat outside, because cats may also carry rabies bacteria, the treatment method is the same as that of being bitten by a dog.
