6 Reasons That Explain Why Your Cat Is Drooling

Last Updated on July 8, 2021 by Jenny

Drooling is not very common for most cats, so every time you notice it, it is best to try to understand why it is happening. Is drooling normal in cats? And if so, what is the difference between normal salivation and pathological drooling?

Is there something you can do to help your cat when it happens? When is it time to go to the vet? In this article, we will tell you everything you need to know about cat drooling, what causes it, and what you can do to help your cat when it happens.

Normal Salivation vs. Drooling

Salivation is absolutely normal in cats. It is a reflex (the salivary reflex), just like it is for humans, and it has a number of roles in the body’s neurophysiology. It is perfectly normal to salivate when you feel the smell of food you like, right?

And the hungrier you are, the more you salivate more when this happens. It is the same for cats. So, if you notice your cat is salivating a bit as you are about to give it its food bowl, then rest assured that they are simply eager to eat.

Salivation, however, stops being normal when it involves a large amount of saliva and when it happens for a long period of time. If you see saliva sliding down your cat’s mouth, then that is no longer normal and you should examine the cat to find out what is causing the drooling.

In some cases, you may even see saliva cascading out of the cat’s mouth or piling up in a puddle on the floor. If you notice this, then you are dealing with pathological drooling and you should call up your veterinarian.

What Causes Drooling in Cats?

Excessive salivation, also called ptyalism appears in two types of situations:

  • When the cat produces too much saliva.
  • When the cat is unable to swallow the saliva that it produces.

In both these situations, the cat drools.

There can be many causes for excessive salivation, but the most serious of them all is rabies. This is the first cause that your veterinarian must exclude. If your cat has received a vaccine for rabies in the last 12 months, then it should be safe. However, if you also notice some of the other signs of rabies, such as sudden aggression, vocalization, muscle spasms, then you should get away from your cat, isolate it in a room, if possible, and call your veterinarian immediately.

Please note that rabies cases are not common anymore. This is largely due to vaccination, which is why it is essential that your cat receives this vaccine. You should, however, know the symptoms of rabies so that you are able to recognize it and keep yourself safe.

Aside from rabies, there are many other causes for a cat’s drooling. Here are the most common ones:

1. Exposure to Toxins

When exposed to certain toxins, cats start to drool. In most cases, the drooling is quite dramatic – the salivation is continuous and in large quantities. Cats ingest, lick, or chew these toxic substances and then begin drooling. This includes pesticides, detergents, poisonous substances, special cleaning substances, etc. If your cat happens to lick or ingest detergents that you use around the house, one of the first signs is the drooling.

If you notice this, you need to take your cat to the vet as soon as possible. This is a medical emergency because these chemicals can cause tremendous damage to the cat’s organs in a matter of hours. If you notice that your cat is drooling continuously until the fur around its mouth and chest is wet, then it is best that you take it to the vet.

Sometimes, it might be difficult to figure out what the cat might have ingested. Don’t wait! It is best that you first take the cat into emergency care so that gets the first line of treatment. While detergents and pesticides are the first things you check when you suspect exposure to chemicals, there are other household items that are dangerous for your cat that you may have overlooked, such as air fresheners or plants. Read about the tragic story of a cat that was poisoned because of a faulty plug-in air freshener.

A common situation when cats are exposed to pesticides and start drooling is when external anti-parasitic medicine (for fleas and ticks) is applied. These are oily substances that come in small vials. They are usually applied on the back of the cat’s neck, precisely because this is an area that it cat’s reach. The oily substance is quickly absorbed into the skin, but some traces of it remain on the cat’s fur.

Then, when it starts to wash, it might get a very small quantity of the medicine on its paws, which it will lick. When the cat ingests a small quantity of anti-parasitic medicine, it starts to drool. In most cases, the drooling stops rather quickly, so there is nothing to worry about. However, if the drooling does not stop, then it is time to take the cat to the vet.

2.Oral Cavity Issues and Dental Disease

Drooling is a common symptom of oral and dental disease because the salivary reflex is activated. Here are only some of the cases when cats drool due to issues of the oral cavity:

  • Tartar deposits – if a large quantity of tartar is deposited on the cat’s teeth, it will no longer be able to close its mouth properly, which will cause drooling. Such deposits are associated with periodontal disease.
  • Periodontal disease – Typically caused by tartar deposits, periodontal disease affects the gums and the dental ligaments. The damage to the gums and teeth might be significant enough to cause drooling.
  • Tooth pain – The pain caused by dental issues is sharp and difficult to bear. When this happens, the cat might open its mouth, which will trigger the drooling.
    Cavities and other dental issues – Quite a few dental issues are associated with salivation because of the local trauma to the oral cavity and because the cat might try to reach the affected area.
  • Pathological growths in the oral cavity – This includes both benign growths and oral cancer. These often make it impossible for the cat to close its mouth properly, which triggers the salivary reflex.
  • Dermatological issues of the lips and mouth – These include all types of rashes that occur on the cat’s lips, which may or may not encompass the entire mouth area

A common cause of drooling and nausea in cats, on the other hand, is motion sickness. If you notice this when your cat has been with you in the car, keep in mind that it should stop once the cat gets a chance to relax.

3. Foreign Body or Disease

The presence of a foreign body in the cat’s mouth or elsewhere in their body, such as a splinter or a piece of bone, do not allow the cat to close its mouth all the way. Depending on the place where the foreign body is lodged, the salivation can be more intense.

If you see your cat drooling, a foreign body is the first thing you should be looking for when you examine its mouth. When the cat eats something inappropriate such as a bone, or when it is playing with a toy or an object in the house, it can get something stuck in its gums, teeth, palate or tongue.

If a kitty has a disease, like my sister’s Addie who’s insides had split open and needed emergency surgery, they might foam at the mouth.

4. Trauma to the Oral Cavity

When cats get hit by cars or when they get into fights, they often get injuries of the oral cavity, which is usually associated with heavy drooling. Here are some of the most common situations:

  • Orthopedic issues of the jaw or the temporomandibular joint – These include fractures, dislocations, inflammations, and many other issues. The salivation is often the first sign of the orthopedic issue. The cat can’t close its mouth all the way, which causes them to drool. Since the problem persists for a longer period of time, the drooling will as well.
  • Scratches and bites – When cats get into fights with other cats or with dogs, they can get scratches or bites on their lips and mouth area. These cause heavy inflammation and can get complicated with infections. They are also associated with drooling.
  • Burns – When cats chew on cable chords or touch hot surfaces, they can get burns around their mouths. The heavy inflammation causes them to salivate heavily.

5. Esophageal Issues

If the cat can’t swallow the saliva it produces, it drools. This can happen when the cat suffers from esophageal lesions. These are commonly associated with pain and loss of appetite. The cat often extends its head and neck because of the intense discomfort in the area.

6. Aversion to Taste

Sometimes it is as simple as the cat not liking the taste of something you might have forced into their mouths – like when I tried to give my parents’ 16-year old Ragdoll cat, Caymus, CBD oil straight from the dropper.

What To Do If Your Cat Is Drooling

If you notice that your cat is drooling, you should never ignore it. As you’ve seen, there can be some serious health issues that have caused the cat to salivate. Ignoring the drooling means ignoring the underlying issue, which can be very dangerous and even fatal for the cat. Here’s what you can do:

Begin by answering these questions:

    • How much is the cat drooling? – The quantity of saliva is extremely important. While heavy drooling is always an issue, a small quantity of saliva may be nothing to worry about.
    • How long has the cat been drooling? – If the drooling is continuous, then the cause is most likely a serious one. Try cleaning the cat with a cloth or a paper towel. If the drooling persists, then you should not ignore this.
    • How is the cat’s general state? – If the cat is alert and in good shape, then the cause might be minor. However, if the cat is apathetic, breathing heavily or breathing faintly, then the drooling is most likely the symptom of something serious. If the cat is drooling and its general state is affected, take your cat to the vet.

Examine the cat’s mouth

As you’ve seen in the list above, there can be a lot of cause for the drooling, but most of them are related to the oral cavity. That is where you will find a lot of relevant information about what happened, so you should examine the cat’s mouth.

Here’s what you can do:

  • Examine the lips – Begin your examination with the lips. Look for rashes, scratches, bites, fur loss, inflammation, or anything out of the ordinary such as enlarged lips or the presence of blood. Most oral cavity trauma also presents with lip lesions.
  • Examine the cat’s mouth – Wipe the saliva from the cat’s mouth and open it gently. Look for lesions, foreign objects, and growths. If you notice any blood in the cat’s mouth, you need to take the cat to the vet.
  • Examine the cat’s jaw – Palpate the cat’s jaw gently to look for breaks or bumps. If you notice that the cat has its tongue out, this should be a sign that it can’t close its mouth. Palpate all the way to the temporomandibular joint. Try to see if the area is painful or inflamed. Please note that jaw fractures and issues of the temporomandibular joint are medical emergencies because they prevent the cat from eating and drinking. If you notice anything out of the ordinary in this area, it is best you speak to your vet.
  • Examine the gums – Gently push up the cat’s upper lips to examine its gums. Their natural color is light pink. If you notice that the gums are white, reddish, or yellow, then you should speak to your vet about it. If you notice any lesions to the gums, you should mention those as well. Remember to look all the way to the back and then, switch to the lower area. Pull the cat’s lower lip down and examine the gums.
  • Examine the teeth – Look for cavities or other lesions, tartar, or inflammations of the gum surrounding the teeth. Look for teeth that are broken or dislodged. Keep in mind that dental issues are usually painful, which might make the cat restless. If you notice any dental issues, then you should take your cat to see a veterinary dentistry specialist.
  • Examine the tongue – The normal color of the tongue is pink. If you notice that the cat’s tongue is either paper white or dark red or if you notice any cuts, scratches, or other lesions, then you should take the cat to the vet because this is a delicate area.

    I have a tiger tabby and he drools but only when he sleeps. If I wake him up from sleep sometimes he coughs on his saliva. It doesnt happen every time he sleeps but if he has been sleeping for a while or in a deep sleep.

  2. Pam says:

    My cat started drooling excessively this past summer. We promptly took him to the vet where it was determined that he had an ulcer on his tongue. It was not determined how the ulcer occurred. He was given pain medication and put on a soft food diet ( almost like soup). That did the trick and there was a noticeable improvement within a few days. He fully recovered and there has not been another incident – thank goodness. Thanks to all the vets out there that really care and do their job so well.

    I had this problem with 1 of my Queens, Billie Jean (seal tortie bicolor, age 8). After her vet R/O dental, throat, injury issues, rabies (there hasn’t been a case of rabies in an indoor only cat in Los Angeles County since
    1987. She suspected it may be neurological, (she has a hx of grand mal seizures),so had her seen by a feline neurologist. She did labs, and an MRI. Discovered it wasn’t neurological, but she had BSOM (bilateral serous otitis media…infections in both middle ears). They did surgery to clean out the infections, and she was on meds for 4 months. It was over $5,000, but, Billie Jean is well worth it!

  4. Beth Morey says:

    Of all the cats I’ve known and loved in 74 years, only a few drooled with delight. I have two girls, Darling Trudy (Seal Point Himalayan or Ragdoll, age 9) and Calliope (Domestic Shorthair, age 7), who do it now. Both are rescues. When they’re in the lap of luxury, enjoying a wonderful petting session, they drool just enough to dampen their chest – and my hands, depending on their location. It’s a sign of ecstasy! This habit seems to go right along with stomping/ “making biscuits”. My kitties stomp and drool at the same time.
