The makers of Cat Piano were probably counting on that when they sent me an email about a contest involving Piano Cat owners posting videos of themselves using the product. You can check out all the contest info on their site. They're giving away a Nintendo DS.
Cat Piano replaces the tired old piano sounds with, you guessed correctly, cat sounds. From the soothing tones of House Cat, to the frightening howls of Furious, the various cat sound modes are a great way to irritate anyone in a 20-foot radius.
I can't enter the contest, but I figured I'd give it go playing the only song I know on the piano, When the Saints Go Marching In.
