After cleaning the wound thoroughly with soap and water, see a doctor immediately to start the series of shots (usually four doses over 14 days) and receive Rabies Immune Globulin, which is given with the first vaccine dose.

The 10-day observation period for a biting dog, cat, or ferret is a standard public health practice to determine rabies risk: if the animal remains healthy for 10 days after biting someone, it wasn't shedding the rabies virus in its saliva at the time of the bite, meaning the exposed person usually doesn't need rabies post-exposure shots (PEP). This quarantine ensures the animal is available for monitoring, preventing unnecessary euthanasia for brain testing and avoiding expensive PEP for the bite victim if the animal stays healthy.

This rule helps identify potentially dangerous injection-site sarcomas, rare tumors that can develop in cats, prompting biopsies for suspicious masses.
