We've heard of doing a lot of things in your sleep: Walking, raiding the fridge, even driving a car in some extreme Ambien-laced cases. But this kitten must be some kind of savant, because he gets sleepy and plays the harp.
Granted, there's no actual harp there, but just imagine if there were. Imagine the beautiful sounds he'd be making with his tiny paws.
Could this be the future's Keyboard Cat?
