Holy moly! This is not a nursery–this is a gladiator school! See the kittens practicing their lethal moves. There’s a victim in there somewhere, but we only see his or her leg. “Where’s the rest of me?” Dude, you’re in there with all those kittens and you have to ask that?
Oddly enough, there are no piggies in this video. And it looks like baby goats are the champions of hitching piggy-back rides.
By the way, I recommend not encouraging your kittens to jump onto your back for a ride. This becomes much less amusing when they’re full-sized cats. And, uh, when you’ve got company, or a repairman, they might find it even less amusing.
