There's a reason the old saying goes, "curiosity killed the cat," and not the horse, lemur, pumpkin or whatever else you might imagine curiosity could get the best of. It's because kittens have an insatiable need to explore every crevice and hiding spot available in an attempt to turn mundane items like string, pen lights and yes, even the air, into playthings.
This kitten has met his match in the form on a hamster's rolling ball. We could barely fit a chubby gerbil inside, but he somehow fits all four cute little legs, one long tail, and that adorable face inside. Oh, and he doesn't need your help. He's got that whole rolling issue down.
