Every pets deserve their own simulators. In Catlateral Damage you attempt to cause as much destruction as possible in the two minute time limit for points. You'll find out (if you didn't already know from owning a cat) that absolute havoc can be achieved in just two minutes time. Hell, my cat probably only needs one minute.
It's not necessarily the cat sim I want, but it's the cat sim available. In my imaginary cat simulator, you can sleep for 18 hours, catch mice for 1, fight other cats for 3, and spend the rest of the time pretending you want your human to pet you only to scratch them if they try it.
