Catnip (Nepeta cataria)
Catnip was brought to America by early colonists and was considered to be a commercial crop. Numerous medicinal properties have been ascribed to catnip and it has been used in teas, soaks, and poultices. Today its uses are largely confined to feline entertainment as its active ingredient, cis-trans-nepetalactone, is a mild hallucinogen. Rubbing, rolling, and other merry-making actions are produced, though one should be careful as aggressive behavior is often made worse by catnip indulgence. Response to catnip is inherited genetically as a dominant trait which means that not all cats will be affected. Further, kittens under age 6-8 weeks are not able to respond. Catnip is felt to be a safe and non-addictive recreational drug for cats but there is some thinking that overdose can produce seizures. For this reason, it is best not used in cats with a history of seizures. Chronic exposure to catnip may cause an apparent loss of mental faculty and possibly personality change. Also, it is not a good idea to put catnip in a carrier or box for transportation as by the time the cat arrives, some unpleasant mental changes may be in progress making the cat more aggressive and more stressed than he/she would be had no hallucinogens been involved.
