The reason cats bite but not lick is because cats bite the target with their teeth when attacking, but they do not lick the target. This is because a cat’s licking mechanism is mainly for cleaning its own body and hair, rather than for attacking other animals. In nature, cats are generally predatory animals that bite and tear at their prey with their teeth and claws in order to contain and kill it. In the process of biting the target, the cat will not lick the target, but will continue to bite until the target is controlled or killed.
However, it should also be noted that biting cats is not fun, and they may cause harm to people. If you find that your cat has a biting habit, it is best to seek professional help as soon as possible to avoid causing more harm.
