Cats are naturally clean animals, and they use their tongues to groom themselves.
When a cat licks you, they are depositing their scent on you, which helps them to identify you as part of their social group.
Licking is also a way for cats to show affection. If your cat licks you frequently, it's a good sign that they love and trust you.
If you've been sweating or if you have salty skin, your cat may be more likely to lick you.
In some cases, licking can be a sign of a medical condition. If your cat is licking excessively, it's a good idea to take them to the vet.
You can either ignore the licking, or you can pet your cat and show them that you appreciate their affection.
Licking is a natural behavior for cats, and there are a variety of reasons why your cat might be licking you.
