Cats look cute and adorable. That is until they start biting poor unsuspecting human beings. Cats need to be taught good behavior. A lot of biting that is done by a cat is a result of uncorrected bad behavior. Keep in mind that cats came from the wild. Even though now cats have been domesticated and live in close contact with humans, their instincts remain the same. They are born hunters and are equipped with the natural tools designed to hunt a prey.
