Play a CAT PONG game! Warning: It's addictive!

Any ideas on how to make it two-player using arrow keys?

All cats now go in random directions, thanks to @MabonBalavedaKain

However, because it goes in random directions it tends to go through the paddle VERY frequently. Sorry, but there's not much I can do about this.
