Can cats eat catnip?

Short Answer

Yes

Safety Summary

✔ Safe: Yes — completely non-toxic
⚠ Use caution: Overconsumption causes mild digestive upset
✖ Toxic: No

Why

Catnip (Nepeta cataria) is completely safe for cats. The euphoric reaction cats have to catnip is caused by nepetalactone, a compound that binds to feline olfactory receptors. The effect typically lasts 5–15 minutes, after which cats become temporarily immune for about 30 minutes. Not all cats respond — sensitivity is hereditary and around 30–50% of cats have no reaction.

Portion Guidance

Fresh or dried catnip in normal play amounts is fine. Eating large amounts may cause mild vomiting or diarrhea, but this self-resolves.

Risks & Symptoms

Overeating: temporary vomiting or loose stools
No toxicity risk
Very rarely: overstimulation leading to aggression in some cats
