[Death by Mirrors]

Reminds me of a software I had in the nineties where you could adopt a cat, feed it, play with it and have it run around on your desktop like the sheep mdom mentioned - but they also showed a certain personality. One cat was scared and took a lot of patience to warm up to their caretaker, another one was active and loved to hunt the mouse, a third one preferred to be groomed all day.

Now I feel all nostalgic. Need to look if the cd-rom is still lying around somewhere.
