Catnip (Nepeta cataria) is a perennial herb belonging to the mint family Labiatae. It is a weed plant that grows in the upper middle United States and lower Canada. It can also be grown in your garden.
When cats smell catnip, they exhibit a range of behaviors that have been broken down into four components.
The ingredient of catnip that induces the typical behavior is an essential oil, nepetalactone. The response has been shown to be mediated by the olfactory system.(2) The effects can be moderated by several centrally and peripherially acting drugs, and by several environmental, physiologic and psychologic factors indicating complexity to the overall pattern of behavioral (3) The specific mechanism that triggers these behaviors has not been described.
Catnip has also been used for humans in folk medicine.
Catnip is an interesting plant. It is non-harmful to your cat and seems produce a pleasurable response. It is fun for the cat and fun for the cat's owner to see. If you plant it in your yard, expect the cats to come running!
