A cat playing the piano

Have you ever seen how awesome cats play the piano? And generally have you seen any cats playing the piano? I found an amazing funny video with a cool cat.
There is so much sense in its performance! It is playing very expressive and listening to how the piano sounds. Well, actually I always suspected that the cat is a pretty smart animal, but I haven't realized how smart it can be so far. The most surprisingly is that it sits on the chair during the playing and plays "with both hands"!
