Whether you own a dog or not it is no secret or shocking phenomenon dogs drool. What about your cat? Excessive saliva or even a dribble can be cause for alarm for any cat owner because it is a rare occurrence for most felines. If your cat suddenly starts drooling or perhaps has exhibited the behavior before here are the most common reasons why. Either way, it is a good idea to schedule an appointment with your vet to rule out any serious medical issues.

A Happy Kitty

Yes, no joke, there are some cats when relaxed and happy just drool. During petting or cuddling, some might dribble while others truly slobber like a dog. This is still scary especially for someone just getting to know their new furry friend and a trip to the vet is recommended to be sure, but most likely there is no cause for concern.

Motion Sickness

Many pets of all species can experience motion sickness during car rides. You may notice moderate to immoderate amounts of salivation among other symptoms if your cat has motion sickness. Rest assured it is not uncommon and should clear up shortly after the ride is over.


A myriad of toxins exists in and around your home. Cats are naturally curious therefore notorious for getting into things they shouldn’t. House plants, flowers, household cleaners, and other chemicals can lead to poisoning. No matter the symptoms, if you suspect your cat is poisoned immediately contact your local emergency veterinarian hospital (if after hours), your personal veterinarian or call the poison hotline provided by the ASPCA (888) 426-4435 or Pet Poison Help Line (855) 764-7661. Be aware both poison helplines may charge a fee.The Balanced Cat Leaf Raindrops

Foreign Body

With sudden or excessive saliva an object such as string or other small objects may be lodged in the throat. Even if you can see the object it’s best to leave removal to a veterinarian as you could do more harm than good depending on the object and how it is lodged.

Trauma To The Facial Area

Unless your cat is indoor/outdoor trauma to the face isn’t as likely. However, that doesn’t mean an indoor accident of the sort can’t happen. If so, trauma might consist of a fractured or broken jaw and will certainly warrant medical treatment.

Dental Problems

The Balanced Cat Why Do Cats Drool

Folks, dental problems are the number one cause of sudden, excessive and on-going drooling in cats. Dental issues range from simple tartar build-up to full-blown complex surgeries of the mouth. When ignored and left untreated a cat can suffer severely in more ways than one. Yearly check-ups, brushing a cats teeth (if they will let you), or treats that help prevent tartar and keep teeth clean help to stop issues before they start or get worse.


Mouth Cancer

In rare cases, certain types of mouth cancer cause abrupt and extensive drooling. Saliva is heavily produced due to one or a combination of lesions, swelling, pain, and inflammation brought on by cancer. I lost one of my furbabies two years ago to a rare bone cancer of the mouth. My sweet boy’s face started swelling accompanied by a slight on-going drool. I immediately scheduled a check-up with my vet. Honestly believing his issue was due to extreme dental issues since he was a senior. Shockingly, my vet referred us to a specialist the same day, sadly explaining there were no dental issues but most likely cancer. After exams and a few tests, the specialist confirmed the worst.

Bad Taste In Mouth

Seriously, I’m not joking! True story – my first year fostering with a rescue I scheduled a very healthy kitten for his first vet visit. Everything was great, aside from the usual (worms and fleas). No worries, right? My vet administered the dewormer and topical flea med, same stuff as always. About two hours after arriving home this poor baby begins to run in circles not only slobbering immensely but foaming at the mouth like a rabid dog. I rush him back to the vet utterly frantic thinking this kitten is on the brink of death, where I’d already spent around $300 just to pay another $70 for the vet to shrug it off. “Oh he’s ok, she says, sometimes the medicines (even topical!) just put a bad taste in their mouth”. A couple of hours later he was right as rain like it never happened.

Be Prepared

We love our kitties but sometimes this isn’t enough. We may need to go above and beyond by knowing our cat. Knowing his/her quirks (relaxed happy drooling) or if car rides make them sick. Be prepared for the worst outcome and thankful for the best. Making sure you do your research about different diseases and toxins. Keep emergency numbers handy. Schedule yearly vet visits to avoid most issues and an eye out for the drool that might be an underlying sign of a more serious problem.
