Can Cats Eat Oregano? Why This Kitchen Herb Is Risky for Cats

Oregano is a staple in Italian and Mediterranean cooking, but can cats eat oregano? No — oregano is considered toxic to cats and should be kept well away from your feline friend. Here's what you need to know.

Is Oregano Toxic to Cats?

Yes. Oregano is listed as toxic to cats by the ASPCA. It contains compounds including thymol and carvacrol — phenolic compounds that cats cannot safely metabolize due to their limited liver enzyme activity. Both fresh and dried oregano pose a risk.

Symptoms of Oregano Toxicity in Cats

If a cat ingests oregano, symptoms may include:

• Vomiting and diarrhea
• Gastrointestinal upset and stomach pain
• Lethargy
• Blood in urine (with larger amounts)
• Liver damage (with repeated or significant exposure)

What About Oregano Essential Oil?

Oregano essential oil is far more dangerous than the fresh or dried herb. It is highly concentrated and can cause severe toxicity in cats even in tiny amounts. Never apply oregano oil to your cat, use it in a diffuser near them, or allow them access to surfaces where it has been applied.

Hidden Sources of Oregano

Oregano is commonly found in many foods cats might encounter:

• Pizza and pasta sauces
• Seasoned meats and marinades
• Dried herb blends and Italian seasoning
• Herbal teas

Keep all of these away from your cat.

What to Do If Your Cat Eats Oregano

If your cat ate a small amount of oregano, monitor them for symptoms. If they consumed oregano essential oil or a significant quantity of the herb, contact your veterinarian immediately.

Final Thoughts

Oregano is toxic to cats and should never be intentionally fed to them. Keep oregano plants, dried oregano, and especially oregano essential oil well out of reach. Stick to cat-approved treats and safe cat grass for your feline's snacking needs.

Always consult your veterinarian if you suspect your cat has ingested something harmful.
