Why Do My Cat Drool is a common concern among cat owners, and WHY.EDU.VN is here to provide answers. Drooling in cats, while sometimes normal, can also indicate underlying health issues, anxiety, or even simple relaxation. Our comprehensive guide will help you understand the various reasons behind feline drooling and when it warrants a visit to the vet, ensuring your furry friend’s well-being with expert insights and practical advice on cat slobbering, hypersalivation in felines, and cat ptyalism.
1. Understanding Drooling in Cats
Drooling, also known as hypersalivation or ptyalism, occurs when saliva is released from the mouth instead of being swallowed. While drooling is often associated with dogs, it can also occur in cats. In cats, drooling can be a normal behavior, a sign of relaxation, or an indication of an underlying medical condition. Understanding the reasons behind drooling can help cat owners identify potential health problems and provide appropriate care.
1.1. What is Drooling (Hypersalivation/Ptyalism)?
Drooling, or hypersalivation, is the excessive production of saliva. Ptyalism is another term for this condition. This can result from increased saliva production or difficulties in swallowing. The occasional drool is usually nothing to worry about. But frequent or excessive drooling warrants veterinary attention.
1.2. Is Drooling Normal in Cats?
A small amount of drooling can be normal, especially when a cat is relaxed and content. Some cats drool when they are purring or being petted. However, excessive or sudden drooling is not normal and should be evaluated by a veterinarian.
1.3. When is Drooling a Cause for Concern?
Drooling becomes a cause for concern when it is excessive, sudden, or accompanied by other symptoms such as:
- Loss of appetite
- Weight loss
- Bad breath
- Difficulty swallowing
- Oral pain
- Behavioral changes
- Vomiting
- Lethargy
If you notice any of these signs along with drooling, it is important to seek veterinary care promptly.
2. Common Reasons for Cat Drooling
There are many reasons why a cat may drool, ranging from normal behaviors to serious medical conditions. Here are some of the most common causes:
2.1. Relaxation and Contentment
Just like humans, cats can drool when they are extremely relaxed and content. Many cats will drool while being petted, purring, or even sleeping. This type of drooling is usually nothing to worry about. It often occurs because the cat is in a state of bliss and the muscles in its face are relaxed, leading to saliva escaping from its mouth.
2.2. Dental Issues and Oral Pain
Dental problems are a significant cause of drooling in cats. Conditions such as gingivitis, periodontitis, tooth resorption, and oral ulcers can cause pain and inflammation in the mouth, leading to increased saliva production.
- Gingivitis: Inflammation of the gums due to plaque and tartar buildup.
- Periodontitis: Advanced gum disease that affects the structures supporting the teeth.
- Tooth Resorption: A condition where the tooth structure is broken down by the body.
- Oral Ulcers: Open sores in the mouth, often caused by viral infections or immune-mediated diseases.
If your cat has dental issues, you may also notice signs such as bad breath, difficulty eating, pawing at the face, and reluctance to be touched around the mouth.
2.3. Nausea and Gastrointestinal Upset
Nausea can also cause drooling in cats. Cats may experience nausea due to various reasons, including motion sickness, eating something they shouldn’t, or having an underlying gastrointestinal disorder.
- Motion Sickness: Cats can get nauseous during car rides, leading to drooling.
- Hairballs: The accumulation of hair in the stomach can cause nausea and drooling.
- Gastrointestinal Upset: Infections, inflammation, or dietary changes can cause nausea and drooling.
If your cat is drooling due to nausea, you may also notice vomiting, diarrhea, loss of appetite, and lethargy.
2.4. Foreign Objects
Sometimes, a cat may drool if it has a foreign object stuck in its mouth or throat. This could be a piece of food, a small toy, or a plant fragment. The foreign object can irritate the mouth and cause increased saliva production.
Signs that your cat has a foreign object in its mouth include:
- Excessive drooling
- Pawing at the mouth
- Difficulty swallowing
- Coughing or gagging
- Restlessness
If you suspect your cat has a foreign object in its mouth, it is important to seek veterinary care immediately.
2.5. Upper Respiratory Infections
Upper respiratory infections (URIs), also known as feline cold or feline influenza, can cause drooling in cats. These infections are usually caused by viruses such as feline herpesvirus and feline calicivirus.
Symptoms of URIs in cats include:
- Drooling
- Sneezing
- Nasal discharge
- Eye discharge
- Coughing
- Loss of appetite
- Fever
If your cat has a URI, it is important to provide supportive care and consult with a veterinarian for appropriate treatment.
2.6. Exposure to Toxins
Exposure to toxins can cause drooling in cats. Cats may ingest toxins by eating poisonous plants, licking chemicals, or being exposed to certain medications.
Common toxins that can cause drooling in cats include:
- Household cleaners
- Pesticides
- Certain plants (e.g., lilies, azaleas)
- Antifreeze
- Medications (e.g., NSAIDs, human antidepressants)
If you suspect your cat has been exposed to a toxin, it is important to seek veterinary care immediately. You can also contact the Pet Poison Helpline at 855-764-7661 for guidance.
2.7. Stress and Anxiety
Stress and anxiety can also cause drooling in cats. Cats may drool when they are in stressful situations such as:
- Car rides
- Vet visits
- Loud noises
- Changes in the environment
- Introduction of new pets or people
Drooling due to stress is usually temporary and resolves once the stressful situation is over. However, if your cat is chronically stressed, it may experience more frequent drooling.
2.8. Neurological Issues
In rare cases, drooling can be a sign of a neurological issue in cats. Neurological conditions such as nerve damage, brain tumors, and seizures can affect the muscles and nerves involved in swallowing, leading to drooling.
If your cat has a neurological issue, you may also notice other signs such as:
- Loss of coordination
- Head tilt
- Seizures
- Behavioral changes
- Weakness
If you suspect your cat has a neurological issue, it is important to seek veterinary care immediately.
2.9. Rabies
Rabies is a viral disease that affects the nervous system and can cause excessive drooling in cats. While rabies is rare in vaccinated cats, it is important to be aware of this potential cause of drooling.
Other symptoms of rabies in cats include:
- Behavioral changes
- Aggression
- Paralysis
- Seizures
If your cat is not vaccinated against rabies and is showing signs of the disease, it is important to seek veterinary care immediately. Rabies is fatal and can be transmitted to humans.
3. Diagnosing the Cause of Drooling
If your cat is drooling excessively, it is important to determine the underlying cause. A veterinarian can perform a thorough examination and run diagnostic tests to identify the reason for the drooling.
3.1. Physical Examination
A veterinarian will start by performing a physical examination of your cat. This includes:
- Checking the mouth for signs of dental disease, ulcers, or foreign objects
- Palpating the neck and throat for abnormalities
- Listening to the heart and lungs
- Assessing the cat’s overall health and behavior
3.2. Dental Examination
A thorough dental examination may require sedation or anesthesia to properly assess the teeth, gums, and oral cavity. Dental X-rays may also be taken to evaluate the tooth roots and surrounding bone.
3.3. Blood Tests
Blood tests can help identify underlying health issues that may be causing the drooling. Common blood tests include:
- Complete Blood Count (CBC): Evaluates the number of red blood cells, white blood cells, and platelets in the blood.
- Biochemistry Profile: Assesses organ function and electrolyte levels.
- Thyroid Test: Checks for hyperthyroidism, a common cause of drooling in older cats.
3.4. Urinalysis
A urinalysis can help assess kidney function and detect urinary tract infections.
3.5. Imaging
Imaging tests such as X-rays and ultrasounds may be used to evaluate the internal organs and identify any abnormalities.
3.6. Biopsy
If a growth or mass is found in the mouth, a biopsy may be performed to determine if it is cancerous.
4. Treatment Options for Drooling
The treatment for drooling depends on the underlying cause. Here are some common treatment options:
4.1. Dental Treatment
If the drooling is caused by dental disease, treatment may include:
- Professional dental cleaning to remove plaque and tartar
- Tooth extractions for severely damaged or diseased teeth
- Antibiotics to treat infection
- Pain medication to relieve discomfort
4.2. Medication
Medications may be prescribed to treat underlying medical conditions that are causing the drooling.
- Antibiotics: To treat bacterial infections.
- Anti-nausea Medications: To relieve nausea and vomiting.

- Antiviral Medications: To treat viral infections.
4.3. Foreign Object Removal
If the drooling is caused by a foreign object in the mouth or throat, the object will need to be removed by a veterinarian.
4.4. Dietary Changes
Dietary changes may be recommended to manage gastrointestinal issues that are causing the drooling.
- Highly Digestible Diet: To ease digestion and reduce gastrointestinal upset.
- Hypoallergenic Diet: To identify and manage food allergies.
4.5. Stress Reduction
If the drooling is caused by stress or anxiety, strategies to reduce stress may be recommended.
- Pheromone Therapy: Using synthetic feline pheromones to create a calming environment.
- Environmental Enrichment: Providing toys, scratching posts, and climbing structures to reduce boredom and stress.
- Medication: Anti-anxiety medications may be prescribed in severe cases.
4.6. Supportive Care
Supportive care may be necessary to manage symptoms and support the cat’s overall health.
- Fluid Therapy: To prevent dehydration.
- Nutritional Support: To ensure the cat is getting adequate nutrition.
- Pain Management: To relieve pain and discomfort.
5. Preventing Drooling in Cats
