My cat ate Peppermint — what to do
Step by step
- Take peppermint away and remove any plant material from your cat's mouth so they cannot eat more.
- Note roughly how much was eaten and when — this helps the vet judge the risk.
- Do NOT induce vomiting unless a vet or poison-control specialist tells you to.
- Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 (a consultation fee may apply) and follow their advice.
- Watch for drooling, pawing at the mouth, vomiting, loss of appetite, or lethargy, and bring a leaf or photo to the appointment.
This is general guidance, not veterinary advice. Pets vary, and a reaction may be to soil, fertiliser, or pesticide as well as the plant. When in doubt, call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435.
My cat ate peppermint — FAQ
Is peppermint poisonous to cats?
Yes — the ASPCA lists Peppermint (Mentha piperita) as mildly toxic to cats. ASPCA lists Mentha (mint) as toxic to cats, dogs, and horses. The essential oils — primarily menthol and menthone — can cause vomiting, diarrhea, and weakness, particularly in cats, which cannot efficiently metabolize phenolic compounds. The plant itself in small amounts presents lower risk than concentrated oils, but pets should be kept away. Seek veterinary advice if ingestion is suspected.
How serious is it if my cat ate peppermint?
Peppermint is mildly toxic, so most cats get short-lived mouth irritation, drooling, and vomiting rather than a life-threatening reaction. It is still worth a vet call to be safe, especially if your cat ate a lot or symptoms persist.
What symptoms should I watch for?
Signs usually appear soon after chewing: drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy. ASPCA lists Mentha (mint) as toxic to cats, dogs, and horses. The essential oils — primarily menthol and menthone — can cause vomiting, diarrhea, and weakness, particularly in cats, which cannot efficiently metabolize phenolic compounds. The plant itself in small amounts presents lower risk than concentrated oils, but pets should be kept away. Seek veterinary advice if ingestion is suspected. Any worsening or persistent symptoms warrant an immediate vet visit.
Should I make my cat vomit?
No — do not induce vomiting unless a vet or the ASPCA Animal Poison Control Center specifically tells you to. The wrong action can make things worse. Call (888) 426-4435 and follow professional advice.
How do I stop this happening again?
Keep peppermint well out of reach, or swap it for an ASPCA non-toxic plant — see the best cats-safe plants list.
