Why Is My Cat Slobbering

Cats are known for their meticulous grooming habits and typically dry, clean mouths, so it can be alarming to see your cat slobbering or drooling excessively. While occasional drooling is normal for some cats, persistent or excessive slobbering may indicate an underlying issue. By understanding more about the causes behind cat slobbering, you can take the necessary steps to ensure your cat's health and well-being.

Why Is My Cat Slobbering?

Slobbering, drooling, or hypersalivation refers to the excessive production of saliva in a cat's mouth. While mild drooling can occur in some cats without any cause for concern, frequent or excessive drooling is unusual and often warrants attention.

In most cases, slobbering in cats can be divided into two main categories:

• Behavioral or emotional causes:
  These are typically harmless and linked to excitement, relaxation, or certain behavioral responses.
• Medical causes:
  These can range from dental issues to systemic illnesses and require veterinary attention.

Let’s delve into the most common reasons why your cat might be slobbering.

1. Behavioral or Emotional Causes of Slobbering

a. Contentment and Purring

Some cats drool when they are exceptionally content or relaxed, especially when purring. This type of slobbering is often seen when cats are kneading, snuggling, or being petted by their owners. It’s a sign that they feel safe and comfortable, much like how kittens drool when nursing from their mothers.

• What to look for: If your cat drools only during purring or affectionate moments, this is generally harmless. The drooling will stop once they calm down.

b. Nervousness or Stress

Cats may also drool in response to anxiety or stress. A trip to the vet, a car ride, or the introduction of a new pet can cause a cat to become nervous, which may trigger drooling. This type of slobbering typically resolves once the stressor is removed.

• What to look for:
  Your cat might drool during stressful situations but stops once they return to their normal environment.

c. Nausea

Just like humans, cats can drool when they feel nauseous. Nausea in cats can be triggered by a variety of factors, including motion sickness, gastrointestinal issues, or even side effects from medication. If your cat is drooling and showing signs of nausea (such as refusing food, vomiting, or licking their lips excessively), it’s important to identify and address the underlying cause.

2. Medical Causes of Slobbering in Cats

If your cat’s slobbering persists outside of moments of relaxation or stress, a medical issue may be to blame. Here are some common medical conditions that can cause excessive drooling in cats.

a. Dental Disease

One of the most common causes of drooling in cats is dental disease. Cats can suffer from various dental problems, including tooth decay, gum disease, and abscesses, which can lead to pain and excessive salivation. Tartar buildup and gingivitis can irritate the gums, causing them to become inflamed and sensitive. This discomfort often leads to drooling.

• What to look for:
  Other symptoms of dental disease include bad breath, difficulty eating, pawing at the mouth, and visible tartar or redness along the gumline. Regular dental checkups and cleanings can help prevent and treat dental issues.

b. Oral Infections or Injuries

Oral infections, ulcers, or injuries inside the mouth can also cause a cat to slobber. Cats that engage in fights or chew on inappropriate objects may suffer from cuts or punctures in the mouth. These wounds can become infected, leading to drooling, pain, and swelling.

• What to look for:
  In addition to drooling, your cat may avoid eating, especially hard foods, and may show signs of discomfort when touched around the mouth.

c. Foreign Objects in the Mouth

Sometimes, a foreign object like a piece of food, string, or even a blade of grass can become lodged in your cat’s mouth, throat, or between their teeth. This can cause discomfort, excessive salivation, and difficulty swallowing.

• What to look for:
  If your cat is pawing at their mouth or trying to vomit, a foreign object could be the culprit. Immediate veterinary attention may be necessary to safely remove the object.

d. Toxin Ingestion

Cats are curious creatures, and they sometimes come into contact with or ingest harmful substances. Certain household products, plants (like lilies or poinsettias), or chemicals can cause drooling if ingested. Some cats also react to flea medications applied near their necks by drooling excessively if they ingest any residue while grooming.

• What to look for:
  If your cat has been exposed to toxins, drooling is often accompanied by other symptoms such as vomiting, lethargy, or seizures. This is a medical emergency, and you should contact your vet immediately.

e. Kidney Disease

Chronic kidney disease is common in older cats and can cause nausea, which leads to drooling. Cats with kidney disease may also experience other symptoms, such as increased thirst, weight loss, and a decrease in appetite.

• What to look for:
  Monitor for changes in your cat’s drinking and urination habits, as well as signs of weight loss and lethargy. Regular vet visits can help manage this condition.

f. Liver Disease

Liver disease can result in toxin buildup in the bloodstream, leading to nausea, vomiting, and drooling. This condition is often accompanied by jaundice (yellowing of the skin and eyes), weight loss, and lethargy.

• What to look for:
  If your cat’s drooling is accompanied by yellowing around the eyes or mouth, this could indicate liver disease, and immediate veterinary care is required.

g. Respiratory Infections

Respiratory infections, particularly those affecting the nose or throat, can cause excessive drooling in cats. Viral or bacterial infections that cause inflammation or sores in the mouth and throat can lead to discomfort, prompting a cat to drool. 

• What to look for:
  Look for signs like sneezing, coughing, nasal discharge, or difficulty breathing, which may indicate a respiratory infection.

h. Tumors

Oral tumors, both benign and malignant, can cause slobbering in cats due to irritation, pain, or blockage. While this is a less common cause of drooling, it is more likely to occur in older cats.

• What to look for:
  Tumors in the mouth may cause visible swelling, difficulty eating, or even a noticeable lump. Veterinary consultation and diagnostic tests are essential to determine the nature of the tumor.

When Should You See a Vet?

Occasional drooling, especially when your cat is purring or excited, is usually nothing to worry about. However, you should consult your vet if you notice any of the following:

• Persistent or excessive drooling that does not subside
• Signs of pain or discomfort, such as pawing at the mouth or difficulty eating
• Bad breath, bleeding, or visible injuries in the mouth
• Other symptoms such as vomiting, lethargy, or changes in behavior
• Exposure to toxins or dangerous substances
• Any sign of weight loss, jaundice, or other systemic health problems

Early diagnosis and treatment can make a significant difference, particularly if the drooling is related to a serious underlying condition such as dental disease, kidney or liver issues, or toxin ingestion.

How to Prevent Excessive Drooling in Cats

While not all causes of drooling can be prevented, there are steps you can take to reduce the likelihood of your cat developing some of the more common issues:

1. Regular dental care:
Schedule regular vet checkups and dental cleanings for your cat. Brush your cat’s teeth at home with cat-specific toothpaste to prevent tartar buildup and gum disease.  

2. Monitor your cat’s environment:
Keep toxic substances, plants, and small objects out of your cat’s reach to avoid accidental ingestion or exposure.

3. Provide a stress-free environment:
Reduce stress and anxiety in your cat’s environment by providing familiar spaces, minimizing loud noises, and gradually introducing new pets or changes in the household.

4. Provide proper nutrition:
A balanced, healthy diet can improve your cat’s overall well-being and help prevent diseases that contribute to drooling, such as kidney and liver issues.
