Many animals will bite or scratch an attacker when threatened, and predators use their teeth to catch and kill their prey. When humans are bitten, the bite often becomes infected unless carefully cleansed and disinfected. The danger is acute and potentially life-threatening if the animal has rabies. Other diseases acquired after animal bites or scratches include cat scratch disease, rat bite fever, and, rarely, tularemia and plague.
