Do I need to get a shot if I get scratched by a domestic cat?

A scratch by a domestic cat will require an injection. If there is blood in the wound squeeze out the blood and rinse the wound with alternating running tap water and soapy water for at least 15 minutes, then disinfect the wound with iodophor and go to the hospital for an injection. It is also important to get your cat vaccinated regularly at regular intervals.
