Why Do Cats Drool Excessively?

As a pet parent you may have wondered why cats drool. In some cases you may even be asking why do cats drool excessively! Drooling is usually more associated with dogs, but our feline friends practice the art as well! It’s believed to stem from kittenhood, when kneading the mother produced milk. While not all adult cats drool, some do, and in most cases it’s perfectly normal. In this post you’ll discover common reasons why your cat may be drooling, and when it becomes serious.

I hope to answer your question why do cats drool excessively as well as help put your mind at rest. Though some cases may indicate serious illness, many times it’s caused by treatable conditions.

Common reasons cats drool

common reasons cats drool

The most common reason your cat drools is pure contentment. Petting your kitty, or cuddling her, makes you both very relaxed. While you benefit from lower blood pressure, your cat may start drooling. Some cats are just natural droolers and remain so all their lives, while others only drool when somthing’s wrong.

If your cat is happy, drooling will be accompanied by purring, and your cat will probably be kneading you as well. This is completely normal and a sign you’re probably the worlds best cat mum! If your kitty has always drooled there’s probably nothing to worry about. However if it’s something your cat never did before,it may be a good idea to get advice from your vet.

Drooling when asleep

Waking up with damp patches on the pillow isn’t uncommon for us humans, and the same goes for our feline friends! If you’ve ever seen anyone drool out of the corner of their mouth when sleeping it’s quite hilarious! Well your kitty is no different. Drooling happens when the body is completely relaxed, and a sure sign your cat is sound asleep. In some cases though, this can indicate an over production of saliva. Reasons for this can vary from dental decay to intestinal problems.

However, stress can be another reason your cat drools. Though quite rare, some cats get so anxious during a car journey they start to drool. If it stops afterwards and doesn’t return, you’ll know this is the reason.

Though dogs commonly drool at the sight of food, cats rarely do. It’s no unheard of though, and your kitty may be one of the select few that drool over the sight of of a few tasty treats! As long as she’s eating normally and shows no sign of pain or discomfort you should be ok. Pawing at the mouth or rubbing her face against something could mean she’s trying to soothe a sore area though.

Is your cat drooling when she’s afraid

drooling in cats and fear

It’s not unheard of for cats to drool in response to fear. This could be something as simple as the sight of her monthly flea medication! It never ceases to amaze me how my cat seems to know the spot on packaging! Though he’s not a drooler, some cats are. A ride in the car can be a big cause for anxiety as well, especially if your cat asscociates it with a visit to the vet.

Anxiety in cats will most likely include meowing and even panting in extreme cases. If your kitty gets highly anxious during a car journey, I can highly recommend Feliway. It worked for my cat, and seemed to make her much calmer. She definitely associated going in the car with a visit to the vet!

When drooling becomes excessive

One of the most common reasons for constant or excessive drooling in cats is dental disease. This most often occurs in felines over the age of 3 years. If your cat seems reluctant to eat as well as drools, this may be the reason, and you need to see the vet for advice. Unfortunately, your kitty can’t tell you she’s suffering from toothache, and it’s up to you to find out. Your vet will examine her mouth and plan any necessary treatment with you.

Exposure to toxic substances.

exposure to toxic chemicals can cause drooling

If your kitty has swallowed any toxic substances such as pesticides, spot on flea prevention, caustic cleaning chemicals, or even chewed houseplants, you may notice dribbling or drooling from the mouth. If you think this may be the cause, and it’s happened suddenly, you need to go to your nearest animal clinic urgently. Don’t try and deal with it yourself, as you may cause more harm to your poor cat. Always keep toxic chemicals out of reach, and locked away in cupboards. Cats are very curious animals and will lick anything just to test if it’s food!

There are some houseplants that are highly toxic to pets and should never be inside your home. Cats will eat grass to aid digestion and it’s actually good for them, however other plants can prove dangerous including lilies. Keep those outside, well away from your pets.

Swallowing small toys

Cats are just as likely to play with bits of string or rubber bands, than they are with their own toys. Never leave string, or anything lying around that may cause your cat to choke. Just like babies and toddlars, they sometimes chew things they shouldn’t with dire consequences!

If your kitty has a foreign body such as string stuck in her throat, she will salivate and drool as she tries to cough it up. If you suspect your cat has something stuck in her mouth or throat, don’t try and remove it. You’ll either hurt your cat, or get bitten. The best advice is to get her to a vet as quickly as possible

Can kidney disease in cats cause excessive drooling?

can kidney disease in cats cause excessive drooling

If you’re wondering why do cats drool excessively, you may have considered it being a sign of illness. One of the most common health problems in senior cats is kidney disease. If your kitty is approaching her golden years, she may start showing signs of the illness. One of the symptoms of kidney failure is the appearance of sores or mouth ulcers. This results from the kidney’s reduced ability to filter out harmful toxins.

Your cat will not only be drooling, but drinking large amounts of water as well. There are many other symptoms of kidney disease in cats and a visit to the vet will confirm it.

Squamous skin cancer and drooling in cats

Squamous skin cancer is mostly found in white cats and when caught early can be treated. Though often found on tips of ears or nose, tumours can also grow inside the mouth. If you have a white cat that spends time in the sun you should always take precautions. Oral tumours can be painful, causing your feline friend to drool when trying to eat. Keep an eye on her and notice if it happens constantly.

As mentioned previously, dental disease can also make it painful for your cat to eat, so drooling would be a sign. Feeding soft foods will help, but you need to get her examined by a vet.

Is your kitty just a happy drooler?

I hope I’ve helped answer your question “why do cats drool excessively, and if it’s normal for your kitty. While some cats never drool, others leave wet patches after being petted! Covering your lap with a cloth is probably the best way of staying dry when your feline friend wants to get close!

  1. Thanks for the nice post Katty .I don’t have a cat personnaly but i like them and i learn sonething good from your post.I will share this with my coworker ,he is got a cat .Thank you very much

  2. I enjoyed you site commits and attachments. It appears that you did a lot of research on cats or you already have had dealings with a lot of cat problems. One thing for sure is that it is well established and readable for me to understand things to look out for with cats.

    I do not have any cats but do have a lot of family members that do and this would be a very good read and information for them.

    At first I was a little confused with the dog picture and the picture for the knee exercise but I am sure there is something here I am not seeing and you have a purpose for them, just a thought. One more thing in the second sentence below the picture with the dog for the 3 foods dogs shouldn’t eat you have typed “of” twice and you may want to check it.

    Overall a great layout and read with a lot of great information.

  3. I never realised there could be so many reasons for cats drooling. I would also like to know why I drool in my sleep so if you could shed some light on that, it would be great (hehe).

    Great article, I love your use of images and how the post is broken up into sections.

    • Thank you Sharron:) The reason we drool in our sleep is your muscles become very relaxed, especially facial ones:) Yes, cats have many reasons for drooling, but the main one is pleasure:)

  4. Oh, this brings back memories. One of my parent’s cats (we’ll he was a bit of my cat too) used to come up on your chest if you laid on the couch and start purring and drooling. Like actually soaking a puddle of drool on your shirt. While it was both adorable and a bit disgusting the real problem was that he was a bit of an eccentric persona. He didn’t like it if you tried to remove him. I remember this one particular time he was purring on my chest, only a couple inches from my face. I gently tried to move him and his purring stopped, his claws sunk into my chest and his eyes became wide like plates. I kid you not, I was paralyzed for half an hour or so until he decided it’s enough and decided to leave. I was afraid that I’d move him he would lash out on my face and eyes with his claws. Other than that and a little peeing problem he was a very nice and loved cat. Yeah, that’s what cat drool brings me back lol 😀

    • Thank you for sharing your funny story about your parent’s cat:) Cats are such characters. I can imagine the disgust of being covered in kitty drool lol!My cat is a bit eccentric as well and thinks it great fun to attack my hand if he sits on my lap lol!:)
