Cat drooling: what it means and when to call the vet

See a vet within 24 hours

Some cats drool when they are blissfully happy and kneading. Drooling with pawing at the mouth, bad breath, not eating or foaming may mean mouth pain, a foreign object, nausea or poisoning, and needs a vet.

Common causes

  • Contentment while being stroked (harmless)
  • Dental disease, tooth resorption or gum inflammation
  • Mouth ulcers, often from calicivirus
  • Something stuck in the mouth or around the tongue
  • Nausea
  • Bitter taste — medicines, glow sticks, licking flea treatment
  • Poisoning

What you can do at home

  • Look in the mouth only if your cat lets you safely
  • Never pull on string under the tongue — see a vet
  • Wipe off anything on the fur so your cat doesn’t lick more
  • Think about what your cat may have licked or chewed

What the vet may do

  1. Examine the mouth, sometimes under sedation
  2. Dental X-rays and treatment
  3. Remove foreign objects
  4. Treat poisoning and nausea

Prevention

  • Yearly dental checks
  • Use only cat-specific flea products
  • Keep lilies out of the home

The details

A drooling cat on your lap, purring and kneading, is simply very relaxed — some cats do this all their lives. New drooling is different. In cats, it most often means something hurts in the mouth: tooth resorption, a painful condition where the tooth structure breaks down, is very common in adult cats and easily missed at home.

Sudden heavy drooling or foaming after licking something is often a reaction to a bitter taste, but it can also be the first sign of poisoning. Call your vet if you are unsure.
