Bleeding from a scratch by a feral cat requires an injection, and feral cats are more mobile and may carry rabies virus, etc., so patients need to take this seriously. Since feral cats do not have formal animal immunization, patients bleeding after being scratched are at risk of rabies, tetanus and other diseases. Bleeding after being scratched by a feral cat is a tertiary exposure to rabies, and there is no effective treatment for rabies, so patients should be vaccinated against rabies at the first opportunity. In addition, because wild cats have sharp claws and are often exposed to dirt and sewage, if the patient has deep wounds, they are prone to tetanus infection and also require tetanus vaccination. Patients who are scratched by wild cats can go to the hospital surgery or infection department for proper treatment in a timely manner. In daily life, patients should pay attention to the cleanliness of the wound, keep the area dry, avoid scratching, squeezing and rubbing, and avoid eating spicy and irritating food.
