If you have cats (and you like them) chances are you've tried giving them a sniff of catnip to see what happens. Of my last two cats, only one seemed to notice. Many cats don't respond at all to catnip's fragrance. But that's probably fine with the catnip plant (Nepeta cataria). You see, cats probably aren't the plant's target. 

In this video, you'll learn a bit about how catnip works and what scientists think its active ingredient (nepetalactone) is for and its relationship with common garden pest. Even if you're not all that interested in catnip, the video features lots of clips of cats. Isn't that why we have the Internet?
