Home made computerized cat door

In doing some research for an upgrade to the home made cat door I stumbled upon this fascinating project by

This home made cat door uses a low budget and clever way of taking a picture just before the cat reaches the door to enter. If the picture shows anything in your cats mouth like a mouse the computer tells the door not to let him in. Same thing is true if a skunk or other animal tries to get in. If he's all by himself the computer grants permission and unlocks the door. You can also use this system to keep track of how many times your cat goes in and out, complete with a fancy program that will send a picture to your cell phone every time an event happens.

Our cats have always kept their hunting prizes outside, and Lucy does a great job of keeping other small animals out of the yard, so we won't be going to this extreme. Quantumpictures is working on a self contained unit that will be available from their website in the near future.
