The efficacy and function of catnip is to relieve cats' emotions, calm and relax anxious cats, and soothe cats. Moreover, catnip has a stimulating effect on cats and can make them particularly excited, so catnip can be used to induce cats to play with toys.

Although catnip has many benefits, not all cats are suitable for catnip. It is generally not recommended to use catnip on underage kittens. Cats that are pregnant, taking medication, or eating should not eat catnip.
