Introduction
If the wound is superficial, with no obvious bleeding, and caused by a minor scratch from a domestic cat that has been regularly vaccinated against rabies, emergency rabies vaccination is generally not required. However, the wound should still be cleaned to prevent bacterial infection. If the wound is deep or large, or if there is bleeding, especially from a stray cat that has never been vaccinated against rabies, it is recommended to receive the rabies vaccine within 48 hours.

In general, whether vaccination is needed after a cat scratch depends on the depth of the wound and the condition of the animal involved. If the wound is minor and caused by a domestic cat that has been vaccinated against rabies, vaccination is usually not necessary. However, if the wound is deep and caused by a stray cat that has never been vaccinated against rabies, vaccination is required after the injury. The optimal time for rabies vaccination is within 24 hours after injury, and it is best not to exceed 48 hours. If you experience any discomfort, seek medical attention promptly. Detailed analysis is as follows:

If the wound is shallow, with no obvious bleeding, and caused by a household cat that has been regularly vaccinated against rabies, emergency rabies vaccination is generally not required. However, the wound should still be cleaned thoroughly to prevent bacterial infection.

If the wound is deep or large, or involves bleeding, especially when caused by a stray cat that has never received rabies vaccination, it is recommended to receive the rabies vaccine within 24 hours after injury.

During the vaccination period, ensure adequate rest and avoid strenuous exercise, alcohol, strong tea, coffee, and other stimulants. Additionally, to prevent cat scratches, maintain an appropriate distance from cats and avoid provoking or playing with unfamiliar cats.
