Cats lick their owners mainly as a way of showing affection and bonding. Licking is a grooming behavior cats perform to form close social bonds, and by licking a person, they are expressing trust and affection, marking you as part of their social group or family. Additionally, cats may lick to share their scent with you, which further strengthens their sense of belonging and safety around you. Other reasons cats lick you include tasting interesting or salty residues on your skin, seeking attention or comfort, and sometimes as a way to cope with anxiety or stress. If the licking is excessive, it might indicate anxiety or a medical issue, but usually, it is a positive sign of affection and connection by your cat. In summary, when your cat licks you a lot, it is most often a loving behavior meant to bond and communicate friendliness, familiarity, and security toward you.
