What to do if your cat eats it

No action needed. Eating a large amount of fresh catnip can cause mild vomiting or diarrhea from plant bulk; that passes on its own. The zoomies and rolling are normal and safe.

Common questions

Can a cat overdose on catnip?

No lethal or toxic dose is documented. Too much fresh catnip may cause vomiting or mild diarrhea, which resolves once access stops.

Why does catnip affect some cats and not others?

The response is genetic — roughly one third of cats lack the sensitivity, and kittens under a few months usually show no reaction.

Is dried catnip in toys as safe as the fresh plant?

Yes, equally safe. Keep the amount modest and store it sealed to keep potency.
