I was tempted to post this game at Neatorama, where there is constant complaining about too many cat posts. But the other half of active commenters love cats, so I will refrain. In the game Catstration, you have to control the cat population by throwing a meat cleaver at their testicles. Catch the falling testicles and throw them into your collection. Avoid cat poop and hairballs. If you don't castrate enough cats, they will multiply, just like real cats.
