CatCam

This neat little thing is a camera that this guy makes. It takes a picture every few minutes and stores them on a an SD card. It costs $60 and you have to buy an SD card for it ($15). It will take about 300 pictures and you can set the interval from every few seconds to every few minutes.

I would love to see where our cats go when the escape the house. Put on one on Willy, though and you will get 22 hours a day of the chair where he sleeps.

Here's the link to buy one. They also have a complete unassembled kit for $31. The assembled kit is probably the better deal.
