This is the stupidest thing, but it is guaranteed to put a smile on your face, and a demonic cackle in your throat.

The desktop version is better than the mobile site, IMO.
Really? You got nothing?
Cat got your tongue??
Bwahahahaha
That's awesome!!!!
I was laughing the whole time.
I used to have a small program that would give you a cat that you could drop , etc. and it would land on it's feet. It would randomly come out a suddenly appearing cat door or walk in from the side of your screen and lick it. I've forgotten what it was called .
Another one thats a lot of fun is 'Kitty Cannon'
I think THAT is the one I was trying to remember. It was far more fun than cat bounce.
My favorite desktop critter app was always WinRoach. I think I had that back on my Windows 3.1 machine. It would hide roaches behind all of your windows. When you move or dismiss a window, the roaches scurry across the screen to find a new hiding place. If you're quick on the click, you can splat them before they hide. I hear it's still available for download for modern Windows versions, but I'm a Macintosh.
I also had a lot of fun with Neko. This was a small white cat that would chase your mouse pointer around the screen. If you didn't move the mouse, he'd lick his fur for awhile and then fall asleep.
