Why does one herb turn cats into blissful goofballs? Here's how catnip works, whether it's safe, and how to use it well.
What catnip actually does
Catnip contains a compound called nepetalactone that binds to receptors in a cat's nose, triggering a temporary, harmless response. Cats may roll, rub, drool, zone out, or become playfully energetic. The reaction typically lasts around ten to fifteen minutes, after which cats become briefly immune before it can work again. It's a natural, pleasurable experience — not a drug high in any harmful sense.

Why some cats don't react
Not every cat responds, and that's completely normal. Sensitivity to catnip is inherited, and an estimated one in three cats simply doesn't have the gene. Kittens under a few months old and very senior cats also tend to react little or not at all. If your cat ignores catnip, they're not broken — they just aren't wired to feel it.
Is catnip safe?
Catnip is non-toxic and non-addictive, so there's no real risk of harm. Eating a lot might cause mild, temporary stomach upset, but cats generally self-regulate. There's no danger of a true overdose. Occasional use keeps the effect fresh, since constant exposure can dull a cat's response over time. For the vast majority of cats, catnip is a safe treat.
Using catnip for enrichment
Catnip is a wonderful, natural enrichment tool. Sprinkle it on a scratching post to encourage use, stuff it in toys to spark play, or offer it to help an anxious cat relax and settle. It's especially useful for motivating indoor cats to be active. Interactive catnip play sessions channel hunting energy and add welcome variety to their day.
Alternatives if catnip doesn't work
If your cat is among those immune to catnip, don't worry — there are alternatives. Silver vine, valerian root, and Tatarian honeysuckle produce similar euphoric reactions in many cats, including some that catnip doesn't affect. It's worth trying one of these to find what delights your particular cat and unlocks that joyful play response.
