Scratched by a cat with a scratch bulge, usually means that the scratch is above the surface of the skin, the degree of damage is not serious, there may only be a small break or just a scratch wound, the need for an injection is determined by whether the cat is at risk of rabies. The affected area can be flushed with medical alcohol first. If there is no stinging, the skin is not ulcerated and usually does not need to be injected. If there are small cuts or scratches, the first shot needs to be given within 24 hours. If the cat is clearly scratched by a rabies-vaccinated cat and there is a cut, the “10-day observation method” can be used to closely monitor the cat to determine if the remaining rabies vaccination is needed. If the cat remains healthy during the 10-day observation period, no further rabies vaccination is required. If the cat shows abnormal symptoms or even dies within the 10-day period, or if the patient has fever, swelling, pain, pus or other uncomfortable symptoms, he/she should seek medical attention and complete all doses of rabies vaccine as prescribed by the doctor. In addition, patients should pay attention to protecting the affected area from water and airborne bacteria and viruses to avoid infection. If scratched by a cat that has not been vaccinated against rabies, or if it is not clear whether or not it has rabies, and there are scratches above the surface of the skin and there is a break in the skin, it is necessary to go to the hospital promptly and get all doses of the vaccine actively and as soon as possible after cleaning the wound. In addition, if special circumstances exist, such as poor hygiene or poorer living environment of the cat, there may be a risk of infection and a tetanus shot or appropriate anti-infection treatment is required according to the doctor’s recommendation.
