Injections are required after bleeding from a scratch by a feral cat. Because feral cats are more mobile and may carry rabies virus, bleeding from a scratch by a feral cat should be taken seriously and must be injected. Because feral cats are not formally immunized against animals, patients bleeding from scratches may be at risk for diseases such as rabies and cat-scratch disease. There is no effective treatment for rabies and the lethality rate is high. Bleeding after being scratched by a feral cat is a tertiary exposure and rabies vaccination should be administered at the first opportunity, regardless of the extent of the scratch. In summary, bleeding after being scratched by a feral cat should be promptly injected with rabies vaccine and immunoglobulin, which can effectively reduce the incidence of rabies.
