Cats aren’t known for drooling, but sometimes, spit happens.
Here’s how you can figure out if your cat is drooling because of an underlying medical condition or if it’s just another one of their little quirks.

Does Your Cat Drool When They’re Happy?
Does snuggling with your cat seem to set off the waterworks? Some cats drool when they’re enjoying a nice face rub or a scratch behind the ears. Though not terribly common, there are many cats who have this quirk. The drooling should stop when your cat is up and about. If the drooling has come on suddenly or seems to last throughout the day, it may be a cause for concern. If not, your cat is probably just one of those rare “happy droolers.”

Does Your Cat Drool When They’re Stressed?
Cats can act pretty strange when they’re stressed. They may drool, pant, and even vomit. If your cat only drools when they’re going for a ride in the car or at the vet’s office, and subsides when they’re back to feeling safe and secure, it’s most likely just a case of the stress-related drooling. Try Feliway spray to your cat’s carrier to help them feel calmer in stressful situations.

Are Dental Issues Making Your Cat Drool?
If your cat allows it, take a peek inside their mouth. Are there any obvious signs of dental disease? Can you spot any tumors, sores, or obstructions that could be disrupting their flow of saliva or causing them pain? Do you notice any pungent odors?
Dental issues can make it painful for your cat to swallow. If you find anything suspicious, or just aren’t able to take a close look inside your cat’s mouth, schedule a visit with your veterinarian as soon as possible.

Does Your Cat Have A Medical Issue?
Drooling often coincides with nausea, which can be caused by ingestion of a poison or toxin, liver disease, or kidney disease.
If your cat’s drooling seems sudden, if it persists, if it is accompanied by lethargy, anorexia (refusing to eat), vomiting, diarrhea, or if you’re otherwise feeling concerned, see your vet as soon as possible.
