Need shots for rabies vaccine after being scratched by a 2+ month old cat. If you are bleeding after being scratched by a 2-month-old kitten, you need to get a rabies shot. This is because mammals will have the possibility of carrying the rabies virus and are prone to rabies if they are not vaccinated against rabies. There is no effective treatment for rabies and it is 100% fatal once it develops. After being scratched by a cat, you need to rinse the wound with soapy water and disinfect the area. Usually, 24 hours is the best time for rabies vaccination, and it is recommended to inject as early as possible. Note that during the rabies vaccination period, you should maintain a light diet, quit smoking and alcohol, and also keep the skin lesions clean and dry to avoid skin infection.
