Peppermint’s refreshing scent may appeal to humans, but is it safe for cats? The short answer: Peppermint essential oil is toxic to cats, and even peppermint plants can cause stomach upset.

In this guide, we’ll cover:
✔ Why peppermint can be dangerous for cats
✔ Symptoms of peppermint poisoning
✔ Safe alternatives for freshening your home

Why Is Peppermint Risky for Cats?
Peppermint contains menthol and essential oils, which cats cannot metabolize effectively. The biggest dangers include:
1. Peppermint Essential Oil (Highly Toxic)
- Absorbed through skin or inhaled (diffusers can be dangerous)
- Causes vomiting, diarrhea, liver damage, or respiratory distress
- Even diluted oils can be harmful
2. Peppermint Plants (Mild to Moderate Risk)
- Fresh or dried leaves may cause mild stomach upset
- Large amounts can lead to drooling, lethargy, or vomiting
3. Peppermint Candies & Human Products
- Often contain xylitol (toxic sweetener) or other additives
- Sugar-free versions are especially dangerous
Symptoms of Peppermint Poisoning
If your cat has ingested peppermint, watch for:
- Vomiting or diarrhea
- Drooling excessively
- Difficulty breathing (if inhaled)
- Lethargy or weakness
- Pawing at the mouth (irritation)
🚨 Emergency Step: If your cat shows severe symptoms, contact your vet or the ASPCA Animal Poison Control (888-426-4435) immediately.
