After a cat’s claw scratches a slight blood oozing thread, it needs to be treated promptly. The specific steps are as follows:

1. Treat the wound promptly, use soapy water and flowing water, such as Wash the wound repeatedly and alternately with tap water for more than 20 minutes, while trying to squeeze out the blood from the wound and surrounding tissues to minimize the absorption of the virus.

2. Rinse the wound with normal saline, absorb the water with sterile gauze, and then apply iodophor or benzalkonium chloride for disinfection. There is no need to bandage the wound when it is open.

3. Rush to the nearest CDC or community hospital to inject rabies vaccine as soon as possible, preferably within 24 hours but not more than 48 hours, so as to produce antibodies to neutralize the virus as early as possible and avoid the occurrence of rabies.

4. Since the wound is bleeding, it is a third-level exposure to rabies. It is also necessary to infiltrate and inject rabies passive immune preparations around the wound, such as anti-rabies serum or rabies immune globulin.
