Is your cat drooling while they sleep? You’re not alone in wondering about this. While some drooling during sleep is normal, excessive cat drooling during sleep can sometimes indicate an underlying issue. This blog post will delve into the common reasons why your feline friend might be cat salivating while sleeping, from simple relaxation to more complex medical concerns.

Deciphering the Drool: Normal Versus Concerning
Cats are generally fastidious groomers and rarely drool when awake, unless anticipating food or experiencing stress. Therefore, observing drool on their favorite napping spot might raise an eyebrow. The key is to differentiate between a harmless occurrence and a sign that your cat needs attention.
H3: The Relaxation Drool: A Sign of Bliss
One of the most common and endearing reasons for cat drooling in sleep is simply extreme relaxation. Just like some humans might drool a bit when deeply asleep and relaxed, cats can too. This is particularly true if your cat is in a state of deep, blissful sleep, often accompanied by purring or twitching paws.
- Deep Sleep State: When a cat enters a very deep sleep cycle, their muscles relax completely. This relaxation can extend to the muscles around the mouth and jaw, potentially leading to a relaxed jaw that allows saliva to escape.
- Comfort and Security: A cat that feels exceptionally safe, comfortable, and content in its environment is more likely to experience this level of relaxation. If your cat is sleeping in a favorite, cozy spot, perhaps after a period of contentment, this can contribute to drooling.
- Purring and Sleep: Cats often purr when they are content, and this can sometimes coincide with deep sleep. The rhythmic vibrations of purring, combined with muscle relaxation, can contribute to a small amount of drooling.
If the drool is minimal, infrequent, and your cat appears otherwise healthy and happy, this is likely the culprit. There’s no need to worry about this type of cat sleep drooling causes.
H3: The Sleepy Mouth: Anatomy and Saliva
A cat’s mouth is designed to produce saliva, which aids in digestion and lubrication. When a cat is awake, they typically swallow this saliva. However, during sleep, particularly deep sleep, their muscle control can be reduced.
- Swallowing Reflex: The swallowing reflex is largely involuntary but can be less active when deeply asleep. If saliva accumulates in the mouth, and the swallowing reflex is temporarily subdued, it can lead to drooling.
- Open Mouth Sleeping: Some cats naturally sleep with their mouths slightly open. This can be due to their sleeping position or simply a habit. If their mouth is open, saliva can more easily escape.
This type of drooling, often referred to as why cat mouth watering in sleep, is generally not a cause for alarm if it’s a small amount and only happens occasionally.
When Drooling Signals a Problem: Exploring the Causes
While relaxation is a common factor, there are instances where cat drooling in sleep medical reasons should be considered. If you notice increased drooling, or drooling accompanied by other concerning symptoms, it’s time to investigate further.
H4: Dental and Oral Health Issues
Dental problems are a very common reason for cat drooling sleep dental problems. An uncomfortable mouth can lead to increased saliva production and, subsequently, drooling, even during sleep.
- Gingivitis and Periodontal Disease: Inflammation of the gums (gingivitis) or more severe gum disease (periodontal disease) can cause pain and discomfort. This irritation can stimulate saliva production, and an uncomfortable mouth might relax open during sleep, leading to drooling.
- Tooth Abscesses or Infections: Infected teeth or abscesses are painful and can significantly increase saliva. The discomfort can persist even when the cat is resting.
- Mouth Sores or Ulcers: Cats can develop sores or ulcers in their mouths due to various reasons, including viral infections (like feline herpesvirus or calicivirus), autoimmune conditions, or even certain medications. These painful lesions will often cause drooling.
- Foreign Objects: Sometimes, a small object like a piece of string, a bone shard, or even a piece of dry kibble can get lodged in a cat’s mouth, between their teeth, or on their gums. This can cause irritation, pain, and increased salivation.
- Oral Tumors: Growths in the mouth, while less common, can also cause irritation, pain, and drooling.
If you suspect dental issues, look for other signs like bad breath, reluctance to eat hard food, pawing at the mouth, or visible redness or swelling of the gums.
H4: Digestive System Concerns
Disruptions in the digestive system can also manifest as drooling, even during sleep. This is a less direct cause but still a possibility to explore.
- Nausea and Upset Stomach: Just as humans might feel nauseous and salivate more, cats can too. If your cat is experiencing an upset stomach or motion sickness (less likely during sleep, but possible if they are dreaming of such an experience), they might drool. This is often part of the cat drooling sleep digestive issues.
- Gastrointestinal Irritation: Certain foods or ingested toxins can irritate the stomach lining, leading to increased saliva production as a protective mechanism or a sign of discomfort.
- Esophageal Issues: Problems with the esophagus, such as inflammation or blockages, can make swallowing difficult and lead to saliva pooling in the mouth, resulting in drooling.
Other symptoms associated with digestive issues might include vomiting, diarrhea, loss of appetite, or lethargy.
H4: Respiratory System Problems
Breathing difficulties can also contribute to drooling, especially if the cat is struggling to breathe comfortably during sleep.
- Nasal Congestion: If a cat has significant nasal congestion due to allergies, a cold, or other respiratory infections, they may struggle to breathe through their nose. This can lead them to breathe through their mouth, which can cause their mouth to dry out, paradoxically leading to more saliva production, or simply allow saliva to escape if their mouth is open. This falls under cat drooling sleep breathing issues.
- Asthma or Other Lung Conditions: Cats with respiratory diseases might experience difficulty breathing, which could lead to panting or mouth breathing during sleep, and thus drooling.
- Upper Airway Obstruction: Although rare, an obstruction in the upper airway could cause drooling as the cat tries to maintain an open airway.
Look for signs like noisy breathing, wheezing, coughing, or open-mouth breathing while awake.
H4: Neurological Disorders
In some cases, drooling can be linked to neurological issues that affect muscle control, including those of the mouth and throat.
- Seizures: While less common, some cats might experience mild seizures or post-ictal (after-seizure) effects that can manifest as drooling. This is a more serious concern and would likely be accompanied by other seizure symptoms.
- Facial Nerve Paralysis: Damage to the facial nerves can affect the ability to close the mouth properly, leading to drooling. This might be due to injury, infection, or inflammation. This is a key aspect of cat drooling sleep neurological influences.
- Rabies: While highly unlikely in vaccinated cats, rabies is a severe neurological disease that causes excessive salivation. Any sudden onset of severe drooling and behavioral changes warrants immediate veterinary attention and concern for public health.
Neurological issues are often accompanied by other symptoms like disorientation, tremors, weakness, or changes in behavior.
H4: Stress, Anxiety, and Discomfort
Cats are sensitive creatures, and their emotional state can influence their physical reactions, including drooling.
- Anxiety or Fear: Just as some cats drool when stressed or anxious (e.g., during a vet visit), it’s possible that a cat experiencing nightmares or a feeling of insecurity during sleep might exhibit drooling. This can be related to cat sleep discomfort drooling.
- Pain or Discomfort: If a cat is experiencing pain elsewhere in its body, it might not be able to relax fully even in sleep, and this discomfort could manifest as drooling.
- Dreaming: While it’s speculative, some believe that very vivid dreams, especially those involving intense experiences like hunting or running, could lead to muscle twitches and a relaxed jaw, resulting in drooling.
If stress or anxiety is suspected, consider environmental factors that might be disturbing your cat’s sleep.
H4: Ingesting Irritants or Toxins
If your cat has ingested something that irritates their mouth or digestive system, it can lead to increased saliva production.
- Chewing on Plants: Some common houseplants are toxic to cats and can cause oral irritation, nausea, and drooling. If the ingestion happened before sleep, the drooling might continue.
- Household Chemicals: Accidental exposure to cleaning products, certain medications, or other chemicals can be dangerous and cause excessive salivation.
- Certain Foods: Some human foods can be problematic for cats. For example, very spicy foods or certain ingredients could cause an upset stomach and drooling.
It’s crucial to ensure your home environment is safe and free from potential toxins that your cat could ingest.
H4: Reactions to Medications
Certain medications can have drooling as a side effect. If your cat has recently started a new medication, discuss this with your veterinarian.
- Sedatives: Some sedatives used in veterinary medicine can cause relaxation of the jaw muscles, leading to drooling.
- Other Medications: Certain anti-nausea medications or treatments for gastrointestinal issues might list increased salivation as a potential side effect.
Always administer medications exactly as prescribed by your veterinarian and report any unusual side effects.
When to Seek Veterinary Advice
While occasional light drooling during sleep is usually nothing to worry about, there are times when you should consult your veterinarian.
H5: Red Flags and Warning Signs
Pay attention to the following signs, which may indicate a more serious issue:
- Sudden onset of excessive drooling: If your cat suddenly starts drooling significantly more than usual, especially during sleep.
- Drooling accompanied by other symptoms: This includes vomiting, diarrhea, lethargy, loss of appetite, difficulty breathing, coughing, wheezing, or any signs of pain.
- Thick, foamy, or bloody saliva: This can indicate more severe oral irritation, poisoning, or internal bleeding.
- Bad breath: Persistent bad breath is often a sign of dental problems.
- Pawing at the mouth: This suggests oral discomfort or pain.
- Drooling that persists when awake: If the drooling continues or worsens when your cat is awake.
- Changes in behavior or demeanor: If your cat seems unwell, distressed, or uncharacteristically lethargic.
- Known ingestion of toxins: If you suspect your cat has eaten something poisonous.
H5: What Your Vet Will Do
Your veterinarian will conduct a thorough examination to determine the cause of the drooling. This may include:
- Physical Examination: Checking your cat’s overall health, temperature, heart rate, and respiratory rate.
- Oral Examination: A detailed inspection of the mouth, teeth, gums, and tongue for any abnormalities, injuries, or signs of disease. This might require sedation for a complete view.
- Dental X-rays: To assess the health of the tooth roots and jawbone.
- Blood Tests: To check for infections, organ function, and other systemic health issues.
- Urinalysis: To assess kidney function and hydration.
- Imaging: Such as X-rays or ultrasound of the chest or abdomen if digestive or respiratory issues are suspected.
- Neurological Examination: If neurological causes are suspected.
H5: Diagnostic Tests for Drooling
| Test Type | Purpose | Potential Findings Related to Drooling |
|---|---|---|
| Oral Examination | Assess gums, teeth, tongue, palate for sores, inflammation, foreign bodies. | Gingivitis, stomatitis, foreign object, tumors, tooth decay, abscesses, severe plaque buildup. |
| Dental X-rays | Evaluate tooth roots, jawbone health, and detect hidden dental disease. | Root abscesses, bone loss due to periodontal disease, impacted teeth, fractures. |
| Blood Panel (CBC/Chem) | Check for infection, inflammation, organ function, anemia. | Elevated white blood cell count (infection), anemia (potential blood loss), organ dysfunction impacting health. |
| Biopsy | Obtain tissue sample for microscopic examination. | Diagnosis of tumors, inflammatory conditions, or infections in oral tissues. |
| Respiratory Exam | Listen to lung sounds, assess breathing pattern. | Wheezing, crackles, or abnormal breath sounds indicating respiratory distress. |
| Neurological Exam | Assess reflexes, coordination, mentation, cranial nerve function. | Signs of nerve damage, tremors, seizures, or disorientation that could affect oral control. |
| Toxin Screening | Analyze blood or urine for specific poisons. | Detection of ingested toxins that cause salivation. |
Managing and Preventing Drooling
The approach to managing or preventing drooling depends entirely on the underlying cause.
- Good Dental Hygiene: Regular veterinary dental check-ups and professional cleanings can prevent or manage dental disease. For some cats, at-home dental care like brushing their teeth or using dental treats can be beneficial, but always consult your vet first.
- Safe Environment: Ensure your home is free from toxic plants and chemicals. Store medications securely.
- Balanced Diet: Feed your cat a high-quality, balanced diet appropriate for their age and health status.
- Stress Reduction: Create a calm and predictable environment for your cat. Provide plenty of stimulation and ensure they feel secure.
- Regular Veterinary Care: Annual or semi-annual check-ups allow your vet to catch potential problems early.
- Medication Review: If your cat is on medication, discuss any side effects with your veterinarian. Never stop or change medication without veterinary guidance.
Frequently Asked Questions
Q1: Is it normal for my cat to drool a little when they sleep?
Yes, a small amount of drooling is considered normal for some cats if they are deeply relaxed and comfortable. It’s similar to how some humans might drool when asleep.
Q2: My cat drools more when they seem happy and purring, is this bad?
If the drooling is mild, infrequent, and only occurs when your cat is very happy and relaxed (often with purring), it’s generally not a cause for concern. It’s a sign of contentment.
Q3: My cat’s mouth waters in its sleep, what does this mean?
“Mouth watering” is another way of saying drooling. Similar to general drooling, it can be due to relaxation, but if it’s excessive or accompanied by other symptoms, it warrants investigation into potential dental, digestive, or other health issues.
Q4: Can I prevent my cat from drooling while sleeping?
Preventing drooling depends on the cause. If it’s due to relaxation, you can’t necessarily stop it and shouldn’t try, as it’s a sign of happiness. If it’s due to a medical issue, treating the underlying condition will stop the drooling.
Q5: How much drooling is too much?
Excessive drooling is subjective but generally means more than a few occasional drops, especially if it’s consistent, foamy, bloody, or accompanied by other signs of illness. If you are concerned, always err on the side of caution and consult your vet.
Observing your cat’s behavior, especially their sleeping habits, is crucial for their overall health. While a little drool during a peaceful nap is often just a sign of a happy cat, being aware of the potential underlying causes can help you ensure your feline companion stays healthy and comfortable. Always consult your veterinarian if you have any concerns about your cat’s health.
