Remember Cooper, the adorable flat-faced cat who dressed up as a banana split for Halloween and ate a banana on video? Well, now he's moved on to playing keyboard duets with another kitty named Marie. I admit that cats playing keyboards has been done to death, but Cooper's definitely a rising star of the cat world.

Oh, and, because it's Halloween weekend, Cooper and Marie are playing some spooky music. Unlike in certain other cat videos, where the cats are clearly being manipulated by their owners *ahem*Keyboard Cat*ahem*, these kitties are actually hitting the keys themselves. (Well, okay, they're being tempted by some treats from off-screen, but the cats are doing all the work.) These Persian kitties might not exactly be piano virtuosos, but they're definitely adorable.
