Can Cats Eat Mint?

With caution — common mint can cause stomach upset and ASPCA lists mint as toxic to cats, while mint essential oils and pennyroyal are more dangerous. Cats are especially sensitive to concentrated oils, so mint is not a good treat choice.

Mint is not a recommended food for cats

Cats should not be fed mint on purpose. ASPCA lists mint as toxic to cats due to essential oils, with vomiting and diarrhea reported after larger ingestions, and concentrated forms such as peppermint oil or pennyroyal are significantly more dangerous.

How urgent is this?

Emergency

Go to the ER now

  • ● Cat was exposed to peppermint oil, mint essential oil, liquid potpourri, or pennyroyal
  • ● Trouble breathing, tremors, weakness, collapse, or severe lethargy after mint exposure
  • ● Redness or burns in the mouth, drooling, or signs the oil got on the skin or fur
Urgent

See a vet within 24 hours

  • ● Cat ate more than a small nibble of mint leaves or chewed a large amount of the plant
  • ● Repeated vomiting or diarrhea after eating mint
  • ● You are not sure whether the plant was common mint or pennyroyal
Monitor

  • ● Cat nibbled a tiny amount of fresh mint leaf once and is acting normal
  • ● Brief sniff of a mint plant with no chewing and no symptoms

Why Mint Is Dangerous for Cats

Mint is not a useful or necessary food for cats. Common garden mint may cause gastrointestinal upset, while mint essential oils are far more concentrated and can be toxic even with small exposures. Cats are more sensitive than dogs to many plant oils because they have fewer liver enzymes to metabolize these compounds, so ingestion, skin contact, and grooming oil off the coat can all be risky.

  • ASPCA lists mint (Mentha species) as toxic to cats, with vomiting and diarrhea reported after larger ingestions
  • Peppermint oil and other mint essential oils are much more dangerous than fresh leaves
  • Cats can absorb essential oils through the mouth and skin, then ingest more while grooming
  • Pennyroyal is a mint-family plant associated with more serious poisoning risk and should be treated as an emergency exposure
  • Skip mint as a treat and call your vet if your cat ate more than a tiny nibble or shows any symptoms

Common Questions

Is mint safe for cats to eat?
Mint is not a recommended treat for cats. ASPCA lists mint as toxic to cats because of its essential oils, and larger ingestions can cause vomiting and diarrhea. A tiny nibble of a fresh leaf may only cause mild stomach upset, but it is still best not to offer mint intentionally.
Are peppermint and spearmint the same risk for cats?
Common culinary mints may be less dangerous than concentrated mint oils, but they are still not ideal for cats and can upset the stomach. If your cat ate a larger amount, or if you are unsure which mint plant it was, call your vet.
Why are mint oils more dangerous than mint leaves for cats?
Essential oils are highly concentrated. Veterinary sources warn that peppermint oil and other essential oils can be poisonous to cats through ingestion or skin exposure, and even a small amount may be harmful. Cats are especially sensitive because they have lower levels of certain liver enzymes used to process these compounds.
How is mint risk different for cats compared with dogs?
Cats are generally more sensitive to essential oils than dogs because of differences in liver metabolism. That means exposures that might cause milder problems in dogs can be more concerning in cats, especially with peppermint oil, diffusers, liquid potpourri, or any product that can get on the fur and be licked off.
What symptoms can mint poisoning cause in cats?
Depending on the form and amount, signs may include vomiting, diarrhea, drooling, pawing at the mouth, lethargy, weakness, difficulty walking, tremors, trouble breathing, or redness and burns on the lips, tongue, gums, or skin. Call your veterinarian right away if any of these happen after mint exposure.
