Is Peppermint toxic to cats?

Mentha × piperita

Toxic to cats

Yes — peppermint is toxic to cats according to the ASPCA. Keep it well away from any cat that chews plants; reactions can be significant. This classification follows the ASPCA Toxic and Non-Toxic Plant List. The ASPCA lists Mint (Mentha sp., family Lamiaceae) as toxic to dogs, cats and horses; the toxic principle is essential oils, and large ingestions cause vomiting and diarrhea. Peppermint is especially oil-rich, so keep pets from grazing it.

What to do if your cat ate peppermint

  1. Remove any plant material from your cat's mouth and move peppermint out of reach.
  2. Note how much was eaten and when, and watch for drooling, vomiting, or lethargy.
  3. Do not induce vomiting unless a vet or poison-control specialist instructs you to.
  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice.
  5. Bring a leaf or photo of peppermint to the appointment so it can be treated correctly.

General guidance, not veterinary advice. If you think your cat has eaten peppermint, contact your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 — do not wait for symptoms to worsen.
