CatCam

This site shows some funny pictures from the life of Mr. Lee, a cat equipped with a strap-on camera. My favorite picture is Trip 1: "Look, is there a cat meeting under a car?"

The "CatCam" takes pictures every few minutes so you can track what your cat does during the day. It would be even better if the camera had WiFi so you could track kitty in realtime on the web.

I bet it wouldn't cost much to prototype such a thing, and interestingly enough, I couldn't find anything like it on the web.
