Why Do Cats Drool?



When most people think of drool, they think of dogs with jowls, like

Saint Bernards



. But dogs arenโ€™t the only ones who can produce excess saliva; cats sometimes drool too, and you shouldnโ€™t ignore it when it happens.So why do cats drool, and when is it time to see the vet? Letโ€™s take a look.

Happy Drooling

Some cats drool when they are happy, excited, or extremely relaxed. A cat who is getting a

serious rubdown from a loving owner, for example, may feel so soothed and serene that they forget to swallow! For many cats, purring

and drooling go hand in hand, but you should still mention it to your


at your catโ€™s

annual check-up. They may want to check your cat out to ensure that the drooling is not related to a larger health issue.RELATED STORY: Is My Cat Weird? 5 Freaky Feline Behaviors

Stress-Induced Drooling

Some cats produce excess saliva in response to

stress or fear. For example, many cats drool in the car, at the vetโ€™s office, before or after receiving an injection, or in response to a bad-tasting or toxic food or medication

(or in anticipation of it, if theyโ€™ve had it before). Oftentimes, stress-induced drooling will be accompanied by stress-related

purring; thatโ€™s right, purring isnโ€™t always positive. Sometimes it signals fear or discomfort.If your catโ€™s drooling is related to stress or fear, it should stop when the catโ€™s circumstances or environment changes. However, if the drooling continues or if you notice any other symptoms

, contact your veterinarian; something more serious may be going on.
