When a cat licks you, it may mean that the cat wants to help you clean your body and comb your hair. It also means that the cat recognizes you. Cat licking is also a sign of missing you. When a cat really misses you, it will lick you to tell you that it misses you.

In addition, cats are very possessive. Cats use the scent on their tongue to mark their territory. Licking you leaves behind its scent and tells others that you belong to it.
