Why Is My Cat Drooling with His Tongue Out? | When to Worry

A cat’s tongue poking out while it’s snoozing – known as blepping – is a classic sign of total relaxation. It’s harmless and often adorable. But when drool starts collecting on the chin alongside that tongue, the picture shifts. Veterinary advice suggests this combination most likely points to an underlying problem, from dental pain to nausea or even toxin exposure.

Many pet owners are caught off guard when both symptoms appear together. Is it the same as a blep? Not quite. In most cases, a cat drooling with its tongue out needs a veterinary checkup to identify the cause. The good news is that with prompt care, most underlying issues are treatable.

What’s Behind the Drool and Tongue

Drooling occurs when a cat either secretes excess saliva or loses the ability to swallow normally. Both mechanisms can lead to saliva spilling over the lips. The tongue sticking out often happens involuntarily, as the cat tries to manage the fluid or relieve discomfort inside the mouth. Dental problems, such as gum disease or tooth resorption, are particularly common culprits.

Veterinarians use the term hypersalivation or ptyalism for excessive drooling. Causes range from local issues like oral inflammation to systemic problems such as kidney disease. Nausea is another common trigger, which can stem from motion sickness, dietary indiscretion, or underlying illness. The tongue protrusion itself may be a response to pain or nausea.

Combined with drool, this behavior warrants a closer look. While a quick blep is usually harmless, persistent drooling with tongue out is a red flag that should not be ignored.

Why the “Blep” Trick Can Fool You

Many cat owners recognize the “blep” – when a cat leaves its tongue out while grooming, sleeping, or after tasting something. This is often a sign of relaxation. But when drool enters the picture, it’s easy to dismiss the seriousness. Understanding the difference can help you know when to worry.

• Blepping vs. Drooling: Harmless blepping typically involves a small, relaxed tongue tip without any saliva. When drool accompanies tongue protrusion, it more likely signals an underlying illness rather than a cute quirk.
• Dental Disease: Dental issues like gingivitis and tooth resorption are among the most common causes of drooling in cats. Some veterinary sources note that most cats over age three show signs of periodontal disease, and the pain can lead to both drooling and tongue extension.
• Nausea: Nausea from motion sickness, kidney disease, or gastrointestinal upset can trigger hypersalivation. Cats may hold their tongue out when feeling nauseous, as if trying to manage the excess saliva or relieve discomfort.
• Toxin Exposure: Ingesting toxic plants, human medications, or household chemicals can cause sudden, severe drooling. This is often accompanied by neurological signs like tremors or seizures, making it an emergency.
• Stress Drooling: Stress from car rides or vet visits can cause temporary drooling in some cats. This type of drooling typically resolves once the stressor is removed and is not accompanied by other symptoms like lethargy or vomiting.

Because the causes vary widely, it’s important to observe your cat’s behavior. If the drooling is new or excessive, a veterinary exam is the safest next step.

When Drooling Becomes an Emergency

Most causes of drooling are not immediately life-threatening, but some situations require urgent care. Dial-a-Vet advises that sudden onset of drooling with tongue sticking out should be treated as a potential emergency, especially if your cat is also lethargic or vomiting. Other red flags include difficulty breathing, pale gums, collapse, or seizures.

Oral injuries from electrical cord burns or sharp objects can cause immediate pain and drooling. Similarly, licking or ingesting toxic substances – such as lilies, certain plants, or human medications – can trigger sudden hypersalivation. For a quick reference on warning signs, the emergency drooling cat guide provides clear guidance on when to seek urgent care.

Any suspected toxin ingestion should be treated as an emergency, as some poisons act quickly. Caustic substances can ulcerate the mouth, leading to pain and drooling. Common household toxins include lilies, which are highly toxic to cats, and antifreeze. If you know or suspect your cat has been exposed, contact your veterinarian or an animal poison control center immediately.

Steps to Take When You Notice the Signs

If your cat starts drooling with its tongue out, don’t panic. The first step is to observe the situation quietly. Is your cat eating normally? Are there any other symptoms like vomiting or discomfort? Here are steps veterinarians recommend to help you respond appropriately and determine if an immediate vet visit is needed.

1. Check for Visible Issues: Look in your cat’s mouth for redness, swelling, broken teeth, or objects stuck in the gums. Be careful – a painful cat may bite, even if normally gentle.
2. Assess Eating and Drinking: If your cat is drooling and not eating, dental problems are a likely cause. Offer soft or wet food to see if your cat shows interest. A complete refusal to eat is a red flag.
3. Look for Toxin Exposure: Check if your cat has access to plants, medications, or chemicals. If exposure is suspected, contact your vet or a pet poison hotline for specific advice.
4. Monitor for Other Symptoms: Watch for lethargy, vomiting, panting, or collapse. These signs suggest a more serious issue that requires immediate veterinary attention.
5. Call Your Veterinarian: For drooling that is new or excessive, schedule a vet appointment. If emergency signs like difficulty breathing or seizures are present, call ahead and head to the clinic right away.

These steps can help you decide how urgently care is needed. Remember, drooling combined with tongue protrusion is a symptom, not a diagnosis. Your vet will need to perform a thorough exam, including oral inspection and possibly bloodwork, to identify the root cause.

What Your Vet Will Likely Check

When you bring your cat to the vet for drooling with tongue out, the first step is typically a thorough oral examination. Dental disease – including gingivitis, periodontitis, and tooth resorption – is among the most common causes. Some veterinary sources estimate tooth resorption affects up to 75% of cats over age five. The vet will look for plaque, tartar, red or swollen gums, and any loose or broken teeth.

Your vet will also evaluate for systemic issues like kidney disease, which can cause nausea and hypersalivation. Bloodwork can assess organ function and identify infections. For a simple reference on what constitutes normal behavior, Purina’s cat blepping explained guide offers clarity on when tongue protrusion is harmless versus worrying.

If the physical exam and initial tests don’t reveal the cause, further diagnostics like dental x-rays or abdominal ultrasound may be needed. Neurological conditions are less common but can include nerve damage or seizure disorders. Treatment depends on the diagnosis: dental cleaning or extractions for oral disease, medications for nausea or infections, and dietary adjustments for kidney issues. The goal is to treat the underlying trigger, which usually resolves the drooling and tongue protrusion over time.

The Bottom Line

A cat drooling with its tongue out is not something to ignore. While a harmless blep is normal, the addition of drool often points to medical issues like dental disease, nausea, or toxin exposure. The best approach is to have your veterinarian examine your cat and rule out serious causes. Observing your cat’s overall behavior and other symptoms can guide how quickly you need to act.

Your vet can assess your cat’s mouth for dental issues like tooth resorption, which is common in older cats, and recommend appropriate treatment to relieve discomfort.
