Have you ever noticed how much your cat drools? Drooling is not so common in cats and you might wonder what it implies when your cat drools if you’re a cat owner.

Drooling in cats can be caused by a variety of factors.

Assessing the problem, getting to know your cat, and involving your veterinarian as needed are all important steps in determining the cause.

In this article, we will discuss possible reasons for this and measures you can take to stop it. Hang in here.

Why Would A Cat Suddenly Start Drooling And Not Eating?

Drooling is frequent in cats when they are kneading or purring. Drooling is a sign of happiness and relaxation that can be traced all the way back to kittenhood.

Kittens massage their paws on their mothers’ breasts to induce milk supply.

These behaviors result in a nourishing link between mother and kitten, and a soothing and pleasant meal.

Feelings of contentment in adult cats often lead to kneading, which induces drooling because of the connection to nursing.

Kneading and drooling are frequently accompanied by purring.

Don’t be startled if drooling develops when your otherwise healthy cat sits in your lap and begins “making biscuits” and purring.

This is entirely natural, and it’s most likely one of the ways your cat expresses his or her love for you.

Cats, rarely drool at the sight of food. However, it is still possible. It’s probably nothing to be concerned about if your cat drools at the sight or smell of food, but not at other times.

Drooling can occur because of stress or fright, such as during car rides, vet appointments, or loud activities.

If your cat appears to be anxious frequently, speak with your veterinarian about your choices.

If the drooling and stress are only temporary and go away on their own, there’s probably nothing to worry about.

Drooling In Cats That Isn’t Normal

If your cat drools all the time, it could be a sign of a health condition. This is especially true if the drooling has nothing to do with happiness or eating.

Even if they appear to be in good health, all cats should be examined by a veterinarian at least once a year for periodic wellness checkups.

Your veterinarian can often spot problems before your cat exhibits any symptoms.

If you see unusual drooling between visits to the veterinarian, contact them straight once.

It’s possible that your cat will need to be examined. Drooling can be caused by a variety of medical conditions.

Reasons Why Your Cat May Be Drooling And Not Eating

Cats, unlike certain dogs, do not drool excessively, and it often goes unnoticed (unless we scratch their chins or find a small damp spot where they have been lying down).

There are a few different reasons your cat may drool, and they all fall into one of three categories:

Inflammation, pain, or difficulty swallowing are all symptoms of pathologic diseases. The cat is attempting to “wipe away” irritations, emotional triggers.

Most drooling is infrequent and includes only a paltry amount of saliva. If your cat is drooling excessively, it’s time to get her checked out by a veterinarian.

Some of these causes can be really dangerous, so it’s always better to catch them early.

1. Cat Drool And Dental Disease

Mouth irritation can be caused by a variety of illnesses, including dental problems.

Drooling is an attempt to remove or soothe the discomfort in the mouth or throat in certain instances.

Excessive drooling is frequently caused by dental problems. Tooth or gum disease affects up to 85% of cats over the age of three.

The resulting saliva may have a bloody tint or a foul odor. “10 Reasons Why You Should Take Care of Your Pet’s Teeth” is a good read.

2. Cat Drool And Respiratory Conditions

Some cats with viral respiratory infections develop ulcers in their mouths, which causes an increase in saliva flow.

3. Oral Cancer And Drool From Cats

Oral malignancies can develop anywhere from the tip of the tongue to the back of the throat in cats, however, they are far less prevalent than dental or viral infections.

Excessive and persistent drooling results from certain disorders. This is a sign that your cat needs a thorough examination from your veterinarian, with a focus on oral health.

4. Foreign Bodies And Drool From A Cat

Excessive drooling is more commonly caused by a foreign body.

A blade of grass, a sewing needle, or a small fishbone can be swallowed by cats and lodge in the mouth or esophagus.

They may claw at their mouths or try to vomit, but the bottom thing is that they are still there.

5. Fear And Drool From A Cat

When a cat is agitated, upset, or afraid, they slobber. Drooling is a common side effect of nausea and the anxiety that precedes vomiting.

Motion sickness can be caused by fear or driving in a car. In either case, it usually comes to a halt at the end of the journey. If your cat drools out of fear, it won’t last long.

6. Happiness and Cat Drool

When cats are extremely calm and like being touched or cuddled, they may slobber. This isn’t unusual, and it’s just a biological reaction to happiness.

Similarly, some cats may drool while sleeping, owing to their relaxed state. Consider the small moist patch on your pillow after a restful night’s sleep.

Drooling like this is usually a sign of a contented cat.

Always visit or call your veterinarian if you have questions; they are your best resource for ensuring your pets’ health and well-being.

Dental and Oral Diseases

Cats can suffer from a variety of oral and dental problems that go unnoticed until they cause severe disease or discomfort.

The cat will frequently salivate excessively because of the pain.

Drooling in cats can be caused by a variety of things, including mouth ulcers, tooth injuries, gum disease, resorptive lesions, and infections.

Your veterinarian will examine your cat’s mouth to look for signs of dental and oral issues.

If dental disease is seen, your vet will probably recommend professional dental cleaning with possible tooth extractions. This procedure must be done under general anesthesia.

Medications like antibiotics may be necessary to address your cat’s dental and mouth issues.


A cat that is nauseous or has been vomiting will often drool a lot.

Nausea and vomiting in cats can have many causes, such as internal parasites, kidney disease, and gastrointestinal conditions.

If your cat seems nauseous, is vomiting, or has a poor appetite, it’s best to see the vet.

After the examination, your vet may recommend lab work to get a better look at organ function, blood cells, and urine content.

The results can help determine the next steps for diagnostics and treatment options.

Foreign Body

If your cat has something stuck in his mouth, it is likely to cause drooling. A string is a common oral foreign body, but other possibilities include toy parts and even grass.

If you see a string hanging out of your cat’s mouth, DO NOT pull it out.

The string may be wrapped around something in the stomach or intestines and pulling can cause major damage. Instead, get to the nearest open vet office.

Toxin Exposure

Cats that have licked, chewed on, or ingested a poisonous substance can develop excess salivation. This includes poisonous plants, caustic chemicals, and toxic foods.

Some topical toxins, such as pesticides or flea and tick preventatives not meant for cats, can cause drooling as well.

If you suspect your cat has been exposed to something toxic, bring your cat to the nearest open veterinarian right away.

If you see something else in your cat’s mouth, proceed with caution before trying to remove it.

Not only can you cause further injury to your cat, but you might also get bitten! It’s always best to get to the vet for an oral foreign body.


Injuries to the mouth can often lead to excessive salivation. Cats that have chewed on electrical cords might suffer oral burns that lead to drooling.

A cat that has been hit by a car may have a broken jaw that causes drooling. Cats that have oral injuries from cat fights often drool.

You may not see evidence of an injury on the outside, but the drooling is a sign that you should see the vet.

If your cat is drooling and you can’t find an obvious normal reason, please contact your veterinarian. Cats are experts at hiding illness.

They rarely show there is a problem until they feel very sick. When in doubt, don’t wait to call the vet. If you suspect your pet is sick, call your vet immediately.

For health-related questions, always consult your veterinarian, as they have examined your pet, know the pet’s health history, and can make the best recommendations for your pet.

How To Prevent Your Cat From Drooling And Not Eating

How to Prevent Your Cat from Drooling Too Much

Taking your cat to your veterinarian for an annual checkup can certainly reduce some problems that cause ongoing or excessive drooling.

Keeping your cat’s vaccinations up to date reduces the chances of illnesses, and having your veterinarian monitor your cat’s teeth and gums will ensure they remain healthy, which also reduces drooling problems.

An indoor cat runs less risk of encountering dangerous animals and situations that can cause poisoning, injury, or respiratory infections compared to outdoor cats.

Introduce your cat to a carrier by placing it in a room nearby with treats and toys inside. When your cat learns to go in and out, you can close the door a few times briefly.

When your cat is used to this action, you can take him or her outside in the carrier and place your cat in the car with a special treat for a little while.

Eventually, you can drive around the block and then go for longer trips until your cat is used to the carrier, the car, and the traveling motion.

Few cats ever enjoy traveling, but you can lessen your cat’s fear and the drooling that accompanies it.

Cats don’t drool very much or very often; therefore, if your cat drools excessively, pay attention.

Note all the other symptoms that are present at the same time and take your cat to a veterinarian and report them. Something is wrong and your cat is depending on you to take care of their problem.

What Should I Do If My Cat Is Drooling And Not Eating? 

Treatment of Hypersalivation in Cats

The best course of treatment will be based on the underlying issue that has been identified. Treatment is only necessary if a health problem is present.


If your cat has been poisoned, the stomach may need to be emptied, depending on the timing.

Certain medications may be administered to counteract the effects of the poison and activated charcoal may be given to stop toxin absorption in the body.

Dental Issues 

Dental surgery may be necessary if abscesses or cavities are found. Singular or multiple tooth extractions may also be needed.

Any wounds should be cleaned, and antibiotics may be prescribed to eliminate infection.


If malignant tumors have been found, surgical removal may be attempted. This is only possible in certain locations of tumor growth.

Both radiation therapy and chemotherapy may be used to fight cancer on a microscopic level.

Upper Respiratory Infection 

Many URIs are the result of viral infections, which have no curative treatment. Supportive care can greatly assist in recovery.

This includes intravenous fluid administration, medications, humidifier use and appetite stimulants.

Kidney or Liver Issues 

These complications may require ongoing care and medication application for the remainder of the cat’s life. Special diets may need to be followed to help alleviate these organ problems.

Foreign Body Presence 

To remove a foreign body causing salivation, the cat may need to be sedated. Certain cases may require surgery.

What Is Hypersalivation?

Cats in general are not prone to drooling.

Because it is uncommon, getting a veterinary assessment is the best course of action, to determine whether the hypersalivation is harmless or serious.

The earlier that a health issue is detected, the more likely it can be successfully treated. Secondary bacterial infections can develop if mouth injuries are left too long. 

A cat may salivate or drool for many different reasons. While drooling is a normal body function, excessive drooling, or hypersalivation, can be cause for concern.

Normal drooling is usually accompanied by excitement or pleasure in the cat. Abnormal drooling appears suddenly, and can last for hours.

A cat who has overheated may begin to hypersalivate. Certain diseases, injuries, and viruses can also cause a cat to drool excessively.

Symptoms Of Hypersalivation In Cats

While most signs of drooling are associated with the mouth, many underlying issues will create multiple signs throughout the body.

All of these secondary signs should be noted, as they can make identifying the health problem easier. Some signs are as follows:

  • Excessive drooling (sometimes lasting for hours)
  • Blood in the saliva
  • Bad breath
  • Inability to eat or drink
  • Swelling or masses in the mouth
  • Vomiting
  • Pawing at the mouth
  • Weakness
  • Lethargy
  • Swollen lymph nodes
  • Labored breathing

Causes Of Hypersalivation In Cats

The cause of the excessive drooling may be local to the mouth or may be a sign of an internal problem.

Sudden onset is often linked with more serious issues. While cats may drool for numerous reasons, the following are the most common.

  • Excitement
  • Nervousness
  • Being near appetizing food
  • Poisoning (from a variety of sources)
  • Medication side effects
  • Foreign body stuck in mouth tissue
  • Teething (in kittens)
  • Injury to the tongue or mouth
  • Insect stings
  • Gingivitis and other gum disease
  • Abscessed tooth
  • Stomatitis (inflammation of the mouth and lips)
  • Acid reflux
  • Rabies
  • Pseudorabies
  • Cancer of the mouth
  • Nausea
  • Upper respiratory infection
  • Liver shunt
  • Chronic kidney failure
  • Heat stroke
  • Viruses (such as feline immunodeficiency virus, feline leukemia virus or feline herpesvirus)

Diagnosis Of Hypersalivation In Cats

When bringing your cat to a veterinarian, be sure to provide the cat’s full medical history to help sort out potential underlying causes of excessive drooling.

The veterinarian will perform a complete physical and oral examination. The cat may need to be sedated for the oral examination to be successful.

All signs will be noted to see how they match with possible health problems. The veterinarian will look for obvious injuries, abscesses, foreign objects, or masses within the mouth.

Full blood work will likely be recommended, including a complete blood count to help detect anemia or the presence of cancer, and a biochemical profile to find signs of metabolic disease.

Urinalysis can help to assess how well the kidneys are functioning. A bile acid blood test will indicate the function of the liver.

Cultures of the urine may identify bacterial infections present in the body. X-rays or ultrasounds may be used to assess organ health or to locate tumors or lesions in the mouth or body.

A biopsy may need to be collected from any masses found.

Recovery Of Hypersalivation In Cats

If surgery has been part of your cat’s treatment, you will need to follow all at-home care guidelines provided by the veterinarian.

This will include monitoring your cat for signs of infection near the incision site. Painkillers, medication, or antibiotics may need to be administered daily.

Your veterinarian will have you return for follow-up appointments to see how the surgery site is healing and to assess the overall health of the cat. 

The prognosis greatly depends on the type of health issue that has been diagnosed.

Dental issues generally resolve with surgical repair, cleaning, and a good oral health routine.

Recovery from being poisoned greatly depends on how fast the the poisoning was identified and what substance has been consumed.

Kidney and liver disease prognoses are guarded and often require lifelong treatment. Most cats will typically recover from an upper respiratory infection.

If the underlying cause of the infection is a virus, it may stay in the cat’s system permanently.

Cancer prognosis depends on how soon it is treated and how aggressive the cancer is.

If your cat is suspected of having rabies, it will need to be quarantined. Vaccines to prevent rabies should be a part of your annual veterinary visit.
