Letting a cat scratch a little bit of a small wound usually requires a shot as well, because there can be skin and mucous membrane damage from a cat scratching a little bit of a small wound. As long as there is a break in the skin, it is at least a second-degree exposure, and there may be a risk of transmitting rabies. After being scratched by the cat should be timely on the wound site for debridement, you can generally use soapy water to wash for more than 15 minutes, and then use medical iodine povidone to disinfect the treatment, and timely medical consultation for rabies vaccination. In the case of a small wound scratched by a cat, if there is no obvious bleeding, usually only rabies vaccination is needed. However, if there is bleeding on the skin after being scratched by a cat, it is a tertiary exposure, and it is recommended that anti-rabies immune globulin be injected at the same time.
