Why does your cat lick you? The reasons are actually sweet

Often, cats like to be physically close to us. Your cat might curl up next to you on the sofa or even climb into your lap. But sometimes, cats take things a step further, and your cat might even lick your bare skin on occasion. Most cats will just give a lick or two and then stop, but this behavior might still have you puzzled. Is your cat grooming you? Trying to send a message? If you’re wondering, “Why does my cat lick me?” you’ll be pleased to hear that the potential reasons behind this behavior are actually pretty sweet. Once you hear these theories, you might feel differently about your cat licking you.

Why do cats lick for no reason?

They don’t. Licking is a common cat behavior, and even though we might not yet understand it, there are probably reasons behind why your cat is licking you. According to BBC Science, there are three theories about just why cats lick people.

The first is one you’ve probably already thought of: Your cat may be licking you because he likes how you smell. Your cat might be attracted to the salt from your sweat or even the scent of a sandwich you just ate. Cats have highly sensitive tastebuds, and they can pick up scents that we can’t smell at all. Licking you might be your cat’s way of investigating.

There’s also a theory that a cat’s licking a person is similar to the mutual grooming some cats exhibit when they trust each other. Cats learn to groom and lick from their mother when they’re young kittens, and as an adult, grooming might be a way to show trust in another being — namely, you. Your cat may be demonstrating that he feels secure around you.

A third possibility may be that your cat is licking you to prove that he owns you. Cats love their own scent, and licking is one way that they spread that scent. Much in the same way that cats rub their heads against you to mark your legs, your cat may be licking you to mark you as his.

Keep in mind that it’s also possible that you may have inadvertently taught your cat to lick you. If your cat licked you and you reacted by laughing, looking at, and petting your cat, your cat may have learned that he can get your attention by licking you. If he repeats this behavior and you react the same way each time, then you’re reinforcing that message. In this case, licking you might be a learned behavior, and it could have become your cat’s way of getting what he wants, whether that’s attention or pats.

Should I let my cat lick me?

In many cases, there’s no harm in letting your cat lick you a little bit every now and then. After all, kitty kisses never hurt anyone, right? You’ll want to wash your hands after if your cat is licking your hands or fingers, but usually, this behavior is pretty harmless. But because cats’ tongues are rough, things can get uncomfortable if your cat tries to lick you too much.

There are some instances where your cat’s licking might become unhealthy, like if he starts licking you excessively because he’s feeling stressed or bored. In these cases, you’ll need to distract your cat or move away from him. Often, keeping a toy beside you that you can toss to or use to play with your cat should be enough to distract him.

Final thoughts on a cat’s licking

Licking is a natural behavior for cats, and if your cat is licking you, chances are it’s a positive thing. While we don’t fully know why cats lick people, the current theories all suggest that your cat is probably pretty comfortable with you to be licking you. So, if your cat licks you on occasion, you can probably take it as a compliment. However, like all cat behaviors, it’s possible for licking to become obsessive. If you notice your cat is licking you excessively or aggressively, then talk with your vet. They might have some insight or might refer you to a cat behaviorist to help you better understand just what’s going on.

Kitten plays with a yarn ball on a string

We love playing with our pets, and they seem to love it back. While dogs might enjoy endlessly chasing a ball or tugging at a rope, cats typically gravitate toward more obvious hunting games. That's why plenty of cat toys involve a small mouse, sometimes stuffed with catnip or another intriguing smell. You can also find cat toys that dangle on a string, something like a fishing pole, for the feline to bat and bite. Well, this particularly clever cat has decided it's her human who needs to practice and is determined to play a little game with him.

We can't exactly tell if this kitty was absentmindedly playing with her toy or if she's a diabolical genius who has set out to teach human owners a lesson; commenters seemed to lean toward the first (and we do too). In the video, the little mouser sits atop a sofa and playfully waves her toy in front of her owner, clearly trying to get him to swing at it. This clip is entitled "Derp has turned the tables playing with derp daddy" and was posted to the Animals Being Derps subreddit, a place for some particularly funny pics and videos of pets.

We don’t typically think of cats as breeds. With canine companions, there is a ton of information on different breeds, including common physical and social traits.

However, felines also have separate breeds beyond just commonly known ones, like Maine Coons and Siamese cats. One you may not have heard of is the snowshoe cat. There’s likely a reason you’ve never heard of this cat, because the breed is rare.

Polydactyl cats: The term sounds exotic — almost like it should be used to describe an amphibian. The unusual term is fitting for something of an odd condition.

A polydactyl cat has a congenital physical anomaly. In layperson’s terms, this means that a cat is born with the condition. They can’t suddenly develop the condition.
