Nora the Piano-Playing Cat
For the most part, there are two kinds of people in the world: cat people and dog people; and I am a dog person. Still, I think this video, found by my mother-in-law, is pretty impressive:
[This video] Features our cat ["our" refers to the people who made the video, not Lisa and me — Ed.], Nora, playing the piano. She's three-years-old, and started playing on her own at about age two. She plays even when no one else is in the room, but her favorite thing is to play duets with my wife's students.
