Cat grass and catnip: what is the difference and how to use them?

🐈 Cats · 🎾 Toys & enrichment · updated 2026-07-11

Under the same shelf label, two very different plants sit side by side: young shoots grown for nibbling, and the euphoria-inducing catnip plant. Confusing the two leads to disappointing purchases. Here is how to tell them apart and get the best out of each for your feline’s well-being.

Cat grass for nibbling: the useful greenery

This is made up of young grass shoots (barley, wheat, oats) that cats happily chew. This natural behaviour helps them bring up hairballs and provides fibre. It is a real plus for indoor cats deprived of outdoor grass, alongside regular brushing. You will find it as grow-your-own kits (3 to 8 €) or ready-grown trays (4 to 10 €). Place the pot away from your houseplants, some of which are toxic: offering dedicated grass is precisely what steers the cat away from dangerous plants.

Catnip: the natural mood-lifter

Catnip (Nepeta cataria) contains nepetalactone, a molecule that triggers a burst of joyful excitement in many cats: rolling, rubbing, licking, intense play sequences. The effect generally lasts around ten minutes, followed by a refractory period. An important point: a significant share of cats is not sensitive to it, as receptivity is hereditary and absent in very young kittens. It is neither a drug nor a danger: catnip is considered safe and non-addictive at usual doses.

In what forms should you use it?

Good practice and limits

Use catnip in small touches, once or twice a week, to preserve its novelty effect. It excels at encouraging the use of new equipment, enriching an indoor cat’s daily life or relaxing certain cats before a stressful event. A few cats respond instead with scattered overexcitement: in that case, keep it for toys and avoid handling moments. A cat that eats a few fresh leaves comes to no harm; in the event of repeated vomiting or unusual behaviour, ask your vet for advice.
