A bite from a cat and a bleeding bite is a situation that also requires rabies prevention. Because the bite is bleeding, there is direct contact of the cat’s saliva with your own blood circulation. This is a level III exposure to rabies and requires rabies vaccination to prevent rabies. However, the case of bleeding bite is a level III exposure and according to the protocol needs to be used in conjunction with rabies immunoglobulin or rabies serum. The rabies vaccination process requires that antibodies be produced about a week after the first injection to produce protection. Therefore, in the case of a bleeding bite, it is possible that the incubation period for rabies has ended after a week or so, and it is possible that the rabies vaccine alone will not provide protection. It is then necessary to use rabies serum or immunoglobulin to bridge the gap that has not yet produced rabies-neutralizing antibodies, which is about a week.
