What Exactly is a Blep and, Why Do Cats Blep?

Don’t know what a blep is?

Well, I’ll explain it.

A blep is when a cat or dog has a part of their tongue out while their mouth is closed. These house pets usually have a cartoonish expression which goes with it—that’s why bleps have gone viral on the internet.

Why Do Cats Blep?

No one knows why cats blep but, professionals have been sharing their theories about this bizarre behavior.

In this section of the blog post, I will share a few reasons why cats blep.

Let’s take a look, shall we?

The Flehmen Response

Amy Shojai, a cat consultant shared that she thinks that the infamous blep may be related to the Flehmen response which basically means that your kitty is basically smelling her environment via her tongue.

As a cat breathes with her mouth open, the pheromones are collected and passed along to the vomeronasal organ on the roof of their mouth.

However, the Flehmen response isn’t the only one responsible.


According to cat behaviorist Ingrid Johnson, cats may not even realize that they’re doing the blep! Other reasons of the behavior could include the cat being on certain medications or relaxants for stress or anxiety.

Anatomic Causes

In some cases, the blep may even be breed-specific.

For example, Persian cats blep and dangle their tongue out because there’s simply no room in their mouth to put it back in!

Accidental Conditioning

Yet another cause for your cat blepping is when you reinforce an incidental blep with cooing, petting, etc. Cats are intelligent animals and are quick to learn things and pick them up.

So, if something is followed by a favorable response, chances are that your kitty will pick it up.
