What Exactly Is a “Blep”?
A blep is when a cat leaves just the tip of the tongue protruding after grooming, yawning, or simply zoning out. Scientists call it benign tongue protrusion. The internet calls it peak comedy. Either way, it’s usually harmless.
Flat-faced (brachycephalic) breeds like Persians and Exotic Shorthairs blep more often because their short jaws make it harder to fully retract the tongue. If you have a Persian, you already know the struggle is real.
The Fascinating Anatomy of a Cat’s Tongue
To understand why the tongue sometimes stays out, it helps to know how it works.
- Covered in backward-facing papillae (those rough spikes made of keratin)
- Acts like a built-in hairbrush during grooming
- Contains fewer taste buds than humans but far more temperature and texture receptors
- Extremely flexible, but the tip is controlled by tiny muscles that can fatigue or relax completely
When those tiny muscles relax too much usually during deep sleep or extreme chill mode the tongue just rests outside the mouth.
Top 10 Reasons Cats Stick Their Tongue Out
1. They Fell Asleep Mid-Groom (The Most Common Reason)
Cats groom themselves for up to 50% of their waking hours. Sometimes they nod off with the tongue still out. You’ll usually see this in older cats or after a particularly thorough bath.
2. Deep REM Sleep
Just like humans drool in deep sleep, cats let their jaw and tongue muscles go completely slack. A tongue-out sleeper is a happy, secure cat.

3. The Classic “Blep” – They Simply Forgot
Cats sometimes finish licking their paw, get distracted by a sunbeam or a random thought, and leave the tongue hanging. It’s the feline equivalent of walking into a room and forgetting why you’re there.
4. Heat Regulation & Panting
Cats don’t sweat like we do. When they overheat, they pant – and the tongue comes out. You’ll see rapid, shallow breathing with the tongue fully extended. Common in summer or after intense play.
Quick fix: frozen treats, cooling mats, or a fan pointed nearby.
5. Motion Sickness
Many cats get car sick. A hanging tongue plus drooling is a dead giveaway. Some cats even stick their tongue out minutes after the ride ends because nausea lingers.
6. Dental Disease or Mouth Pain
This is the big one to watch for.
Gingivitis, stomatitis, broken teeth, or oral tumors can make it painful to close the mouth fully. You might also notice:
- Bad breath
- Drooling
- Pawing at the mouth
- Reduced appetite
If the tongue protrusion is new and accompanied by any of the above, book a dental check immediately. Learn more about cat oral health signs and when to worry.
7. Respiratory Issues
Cats with asthma, allergies, or upper respiratory infections sometimes breathe through their mouth, forcing the tongue out. Look for wheezing, coughing, or nasal discharge.
8. Nausea or Gastrointestinal Upset
Just like humans stick their tongue out when they feel queasy, cats do the same. Common after eating too fast, hairballs, or mild food intolerance.
9. Neurological Conditions (Rare)
In senior cats, mild cognitive dysfunction or small strokes can affect muscle control. Sudden onset tongue protrusion in an older cat should always be checked.
10. Breed-Specific Anatomy
Persians, Himalayans, and British Shorthairs often have slight tongue protrusion because of their flat faces – it’s normal for the breed.
When Is Cat Tongue Protrusion an Emergency?
Call your vet or head to an emergency clinic if you see:
- Blue or purple tongue/gums
- Labored breathing with tongue fully extended
- Sudden inability to close mouth at all
- Excessive drooling with blood or foul odor
- Tongue hanging out + extreme lethargy or collapse
These can indicate oxygen deprivation, severe infection, or toxin ingestion.
How to Tell If It’s Just a Cute Blep or Something Serious
Ask yourself these questions:
- Is it new behavior or has he always done it?
- Does he pull the tongue back in when you call his name or offer a treat?
- Any drooling, bad breath, or appetite changes?
- Is breathing noisy or rapid?
If the answer to 1–4 is “no change, yes he retracts it, no drooling, normal breathing” – you’re almost certainly looking at a harmless blep.
Cat Blep Memes & The Internet’s Obsession
Let’s be honest – half the reason we love bleps is because they’re hilarious. The “cat blep trend” exploded on TikTok and Instagram around 2020 and shows no signs of slowing down. There’s even an entire subreddit dedicated to cats sticking their tongues out.

What to Do If You’re Worried
- Gently touch the tip of the tongue – a healthy tongue should retract immediately.
- Check gums (should be pink, not red or pale).
- Schedule a wellness exam if anything seems off – many dental issues are fixable if caught early.
