As a non-cat owner, catnip is a mystery to me. So, people essentially... drug... their cats? Weird.
Google catnip, and you will find a whole slew of incredible images related to the topic...
...not to mention this YouTube smash hit:
"At least two thirds of domestic cats 'enjoy' the effects of Nepeta, a.k.a. 'catnip.' But do they enjoy it enough? If humans were able to isolate the active ingredient in catnip, could we not use it to become omnipowerful CATGODS? Imagine the possibilities! What fool wouldn't want their own personal cat army? A massive fuzzy force with which to execute your every bidding? A united, unquestioning militia that requires nothing other than unfettered access to the super-powerful catnip products that give their adorable cuddly lives meaning?"
I must admit. I'm sickly curious.
IF you turn your cat into a crackhead, send in video please.
