Okay, this video is interesting, but a little distressing because the kitties do get freaked out. If you're sensitive about animals, please don't watch this.
That said, it's really intriguing to see how the animals try to "always land on their feet" when the direction "down" no longer exists.
Of course, I was predicting they would become ballistic, living shurikens and eviscerate all the humans involved--probably while yodelling out those horrible gobbling noises cats make when they want you to know shit just got real.
Thankfully, these particular feline overlords were--in the name of science--very gracious about not killing everything in sight.
