Cats lick humans for several reasons, primarily related to social bonding and communication. They lick to show affection and create a social bond, similar to how mother cats groom their kittens. This licking can also be a way to mark their territory by transferring their scent onto you. Additionally, cats may lick to groom you, as a form of comfort, or to get your attention for petting, food, or play. Sometimes cats lick because they like the taste of something on your skin, such as salty sweat or food residue. In some cases, licking can be a coping mechanism for stress or anxiety. Overall, a cat licking you is often a sign of affection and trust, though sometimes it may indicate other needs or feelings like stress or the desire for attention.
