YOUR CAT LICKS YOU
Sure, your skin is pleasantly salty, but your cat doesn’t lick you just because you taste good. A cat subjects you to a good licking session for the same reason it does so to itself: grooming. Obviously, you don’t have fur to maintain, but grooming serves other purposes to cats, such as forming close bonds, just like a mother does with her kittens. If your cat grooms you, it sees you as its family.
