Apparently we're coming to the party a bit late on this, but did you know that Center City Philly is home to the latest YouTube star? Her name is Nora, and she's a cat who plays the piano! And by "plays the piano," we mean she likes hitting a few of the keys with her paws. After watching the video, we're really kind of confused as to why some have cried "hoax" or "cat nip." It's cute and all, but it's not like she's playing concertos here or anything. It seems perfectly plausible to us that a cat would come to like hitting a few keys over and over again. Anyways, check out the video below, then, if you haven't had enough, read the Inquirer article, and watch the NBC10 report. You can also find a possible scientific explanation for the cat's behavior here.
