A cat has the ability to both calm your nervous system and provide an immediate outlet for fun and play. Although cats are independent animals who like to scavenge and explore on their own terms, they are also very affectionate with their owners and people they trust.
Why do cats lick you?
To show affection
Licking is not only a grooming mechanism but also a way cats show that they love you. Your cat is creating a social bond by licking you, other cats, or pets.
