What is Catnip?

Catnip is a member of the mint family, Nepata cataria, and it is a strong perennial. The active ingredient that entices cats is Nepetalactone, and it's released when the leaves of catnip are broken. The non-addictive chemical remains active when the leaves are dried and made into a toy, or crushed and sprinkled on a carpet or a towel.

Catnip is a fabulous thing for cats to play with - both dried and fashioned into a small toy, or growing fresh in the garden. Between 10 and 30 percent of all cats are unaffected by catnip - it's an inherited reaction - but most do respond, even big cats such as tigers.

The crushed leaves can also be rubbed against a scratching post to encourage a cat to stop ruining the furniture. This is because the oil in the leaves, while invisible, is still strong enough to attract cats and is more effective than catnip sprays.

The Joy of Catnip

Catnip toys can be kept fresher by storing them in a plastic container between play sessions, but any catnip that isn't still growing will lose its potency over time.
