The "Licking" Mystery Solved: Leading Zoopsychologists Explain the Surprising Reasons Behind This Common Cat Habit
After reading this, you’ll likely stop thinking this is just a cute way to show love.
Even though we’re used to thinking cats don’t really depend on their owners, sometimes they do feel the need to show their love and attachment, proving it in several different ways.
One of those can be licking their owner’s hand, which many think is some kind of cat kiss. However, this behavior can also indicate the animal’s stressed condition; if you’ve noticed your cat keeps licking you more and more often, this is probably a sign that something is wrong with your pet.
Why Do Cats Lick?
A cat’s tongue is covered in tiny keratin hooks called papillae, which point toward the throat. According to behaviorists, this isn't just for grooming; it’s a survival instrument used to rasp meat off bones and regulate body temperature. In the wild, grooming is also a social glue: mothers lick kittens to stimulate their health, and bonded pairs lick each other to create a "group scent”.
The most common reason your cat licks you is because it tries to strengthen your bonds. By licking your skin, your cat is marking you with their scent and mixing it with yours to create some kind of shared family aroma.
However, not all licking has positive meaning. Cats often use repetitive behaviors to self-soothe when they are anxious. If the licking feels frantic, lasts for a long time, or occurs while the cat’s body is tense, it means the animal may be trying to "lick away" their stress.
This can be triggered by boredom, changes in the household, or conflicts with other pets. If your cat starts licking you or themselves obsessively, it’s a sign that their environment might need more mental stimulation or "vertical space" to help them feel secure.
How to Help the Cat If it’s Stressed?
Because those keratin hooks can actually irritate human skin, you shouldn't feel guilty about stopping the behavior if it becomes painful.
Experts suggest "redirecting" rather than punishing. Before the licking begins, try to distract your cat with a toy or a puzzle feeder. If you know a grooming session is coming, keep a soft pillow or a plush toy nearby to place between your skin and their tongue.
