Why do cats stick out their tongues?

Why Do Cats Stick Out Their Tongue

Cats stick their tongue out for many reasons.

Some of them include;

  • Swallowing food and grooming
  • Interpreting their surrounding
  • A sign of relaxation
  • A symptom for sickness


Swallowing food and grooming

Cats roll their tongue to swallow food or groom their bodies through licking.

They can do this because of the unique structure of their tongue.

A feline’s tongue has what you call papillae which are sharp projects that curve backward.



🐱 Fun Fact

The barbs lining a cat’s tongue are made of keratin, the same stuff that makes up the human nail.



The papillae in a cat’s tongue push food backwards to help the cat in swallowing.

These same barbs lift loose hairs off the coat during grooming.

Papillae also make a cat’s tongue sticky which sometimes works against them.


For instance, when a cat lifts hair off it’s caught, it cannot spit the hairball and rather pushes it to the back of its mouth.

This is why most cats swallow hairballs and start choking.

The same can be said for food, if a cat does not like the taste of kibble in its mouth, it has no way of wiping the sticky food from its tongue.


To find relief, a cat will stick its tongue out to stop tasting the food or hair strands.


Interpreting their surrounding/Flehmen Response

Besides swallowing and grooming, cats use their tongue to interpret their surroundings as well.

When cats are in heat season, they can pick up pheromones emitted by another cat through the tongue.


You will notice your feline sticking the tongue out as if to taste the air.

They will then roll their tongue to the upper part of their mouth known as the vomeronasal organ.


This organ interprets the message passed from the tongue and tells the cat what to do next.

If they sniff the pheromones off of a female, the cat knows it is time to mate.


Interestingly, cats will use the same technique to smell your dirty laundry or discover your stash of potato chips.

So when you see your cat stick their tongue out in the air and hold a thinking look, they are just being curious about a new scent they picked up.


A sign of relaxation

Sometimes a cat will be deep in sleep and relax the jaws while at it.

During this snoozing mode, the cat might stick its tongue out unknowingly.


The same thing can happen when you are petting the cat on your lap.

The soft strokes of your hand can send the cat into a deep sleep and stick its tongue out.


This cat sleeping with the tongue-out phenomenon is commonly known as blepping.



A Sign of Sickness

Sign of sickness

Cats sticking their tongue out is normal if it is for any of the mentioned reasons.

But if your feline has its tongue out for more than a minute, then there could be a problem with its health.


Some diseases that can cause your cat to have its tongue out include;

  • Feline Stomatitis
  • Teeth deformities
  • Periodontal disease
  • Cooling down


1. Feline Stomatitis

Stomatitis is a disease that causes ulceration and inflammation around the soft tissue of the mouth.

The disease commonly affects the gums, inside of the cheeks, tongue, and the back of the mouth.


The painful ulcers can prevent a cat from closing its mouth hence the tongue sticks out.

Other symptoms of feline stomatitis include difficulties in feeding, excessive drooling, and panting with tongue out.


2. Teeth deformities

A cracked tooth could cause a cat so much pain whenever they lick their mouths.

Some felines will opt to stick the tongue out to prevent themselves from feeling this pain.

Missing front teeth could also cause a cat to stick its tongue out and drool at the same time.


3. Periodontal Disease

This is an infection of the gums caused by a buildup of plaque in the teeth.

When plaque forms in a cat’s teeth, it provides a breeding ground for bacteria.


The plaque hardens and destroys the soft tissue of the teeth.

This causes bacteria to spread to the roots and form a dental abscess.


A cat may stick its tongue out to prevent it from touching the painful abscess in its mouth.


4. Cooling down

Cats use their tongues and paw pads to cool off.

If it gets too hot in summers, a cat will stick its tongue out to expel as much heat as possible.


If you notice your cat sticking tongue out and drooling, take it to a shady area to cool.

Extreme heat can send a cat into heatstroke.


Final words

Cats sticking their tongue out is normal feline behavior.

But if the habit becomes frequent or goes for more than a minute, your cat could be sick.

Take your cat to a vet to have its oral health checked.
