Written and reviewed by the VetTree veterinary team · Last updated July 19, 2026 · reference information

If your cat is drooling more than usual, possible causes include oral pain from a dental or gum problem, stomatitis, a foreign object in the mouth, or nausea. When drooling occurs with bad breath, pain, or reduced appetite, an oral problem is more likely and a veterinary exam is needed.

Frequently asked questions

Why is my cat drooling?

Oral pain is one common cause. Dental and gum problems such as tooth resorption, fractures, or periodontitis, along with stomatitis or a foreign object in the mouth, can cause drooling. Causes outside the mouth, including nausea, are also possible.

Does drooling mean my cat needs a veterinarian right away?

Arrange a veterinary exam if drooling starts suddenly or continues, or if it comes with blood, strong bad breath, or reduced appetite. Seek care more urgently if vomiting or low energy also occurs.

Could drooling be caused by a dental problem?

It can. Oral pain is a common cause, so drooling with bad breath or signs of pain can point to a dental or gum problem. A veterinarian should examine the mouth.
