Weird Cat Facts: 8 Reasons Your Cat Likes to Lick You

Here's why some kitties groom their humans -- and what to do if yours needs an intervention.

Today’s weird science question comes from Kendraw:

“My cat is obsessed with licking me. She will tolerate pets, but what she really wants to do when she needs attention is to lick me anywhere she can get skin. She won't lick my face, thank goodness, but my arm, elbow, and hand are fair game! She will literally hold me down in her paws and clean me. And it's not just a few licks; she gets quite thorough about it. I've tried bitter spray. No luck. I know it’s a sign of affection, but is there any way I can gently get her to stop?”

Well, Kendraw, you’ve got a question and I’ve got some answers. First I’ll talk about why cats lick, and then I’ll give you some tips on how to persuade your cat that there are much more awesome options than grooming you until your skin is raw.

1. Licking is a means of social bonding

Kittens groom each other, and older cats who aren’t related but get along well also spend time grooming one another. Often they’ll get the spots that are hard for a cat to reach by themselves, such as the top of the head and inside the ears. Exchanging scents through grooming also increases the bond between a pair of cats.

My cats, Thomas and Dahlia, loved to groom each other.

2. When your cat licks you, she’s paying you a huge compliment

A tongue bath from your cat is an indication that she feels totally safe in your presence. You are truly a member of her family, and she reinforces that by cleaning you like her mother cleaned her when she was a kitten.

3. Your cat’s tongue is covered with barbs

Your kitty's tongue feels like sandpaper because it’s covered with papillae -- backward-facing hooks made of keratin, the same material that makes your kitty’s claws. The papillae help cats rasp meat off bones, and they also assist in grooming by acting like a comb to pull out loose fur and dirt.

4. Your cat might be licking you because of anxiety

Some cats get so stressed that they begin licking compulsively. Cats who lick themselves bald are often trying to comfort themselves because they’re stressed. Other compulsive kitties might lick and suck on fabric, plastic, or even your skin.

5. To stop your cat from licking you, distract her

Learn the signs that your cat is about to start licking. Before she starts washing your arm raw, redirect her attention with a toy. If your cat likes catnip, slip a catnip-filled kicker toy in front of her when she’s about to lick you. If she’s not a catnip fan, try a treat-dispensing toy instead.

6. De-stress your cat with interactive play

Play is always good. It keeps your cat fit and trim, and it strengthens the bond between you. Not only that, but the chemicals released during exercise help your cat to relax and feel content.

7. Be patient

It’s not easy to retrain a cat who has gotten used to performing a habitual behavior such as licking. Remember to stay gentle and avoid yelling or intense physical reactions like shoving your cat, tossing her off your lap, or (heaven forbid) hitting her.

Sure, cats lick us all they want, but do they dig it when we try to lick them? Uh, not so much.
