Game For Cats has a title that's about as literal as they come. It's a game. For cats.
It's nothing fancy — just a few variations of "something is moving quickly around the screen" — but that's simple enough for a cat. Because remember: this game is not for humans. It's for cats.
It's a free download, so if you've got a feline and want to keep it busy — or potentially scratch the crap out of your iPad screen — you can grab it here.
