Whats in cap nip that makes the cats go crazy

Catnip is also known by the following names: Cataria, Catmint, Catnep, Catrup, Cat's Heal All, Cat's-play, Cat's Wort, Catswort, Catwort, Chi Hsueh Tsao, Field Balm, Garden Nep, Herba Cataria, Herba Catti, Nebada, Nep.

The active ingredient which causes this is an essential oil called nepetalactone, which can be found in the leaves & stem of the plant. Other constituents include Acetic Acid, Alpha & beta-nepetalactone, Citral, Nepetalactone, Geraniol, Dipentene, Citronellol, Nerol, Butyric Acid, Valeric Acid and Tannins.

When a cat encounters catnip, it usually sniffs it, rubs against it, licks it & finally eats it. It's actually the sniffing that gets produces the high, it's believed that cats eat catnip to bruise the catnip & therefore release more of the nepetalactone. The high produced will usually last between five & ten minutes.

One interesting fact is that when sniffed, catnip will stimulate kitty, however when eaten it will act as a sedative.

Around 50% of cats are affected by catnip, and those who are, are affected to differing degrees. Kittens younger than 8 weeks old aren't able to enjoy it's effects. In fact, they show an aversion to it. The response to catnip appears to be inherited as an autosomal gene. It's not just domesticated cats who enjoy the effects of catnip, many lot of wild species also enjoy it. Cats can smell 1 part in a billion in the air. Males & females, entire or desexed, there appears to be no one group who is more readily affected by catnip than another.
