Catnip A Natural High

here's the scoop on catnip; scientific name nepeta cataria; contains a relative of the hallucogens, an essential oil called nepetalactone. Not all cats have the genetic code needed to 'appreciate' catnip. Those that do will not react favorably until they are 8 weeks old and then not fully until at least 3 months old.
The pleasurable experience of catnip lasts about 15 minutes and is dependent on propicious (sp?) environmental factors. It takes the cat about one hour to recover from this little episode in order to attain another 'high' from the catnip.
No, cats cannot overdose on catnip but some do act 'drunk as a lord'
there is your daily dose data;use it as you will!
