Any scratching by a cat’s claws requires an injection. This is because if the cat is not able to use some means to rule out the possibility of it carrying the rabies virus and the cat scratches a person, this is a typical secondary exposure to rabies, or even a tertiary exposure if there is bleeding. Whether secondary exposure or tertiary exposure, it is possible to transmit rabies to people. Therefore, according to the rabies disposal process, rabies vaccination is required, and in the case of bleeding, rabies human immunoglobulin, or anti-rabies serum, is also required. It is recommended that the first dose of rabies vaccine be administered within twenty-four hours of the scratch. If only the rabies vaccine is administered, the rabies neutralizing antibodies will be produced about a week after the first injection according to the regular procedure, providing protection. If the injection is given later, it is also recommended to go back for another injection.
