Give your cat a Twitter account and have her post updates automatically whenever she sits down on her bed or when she leaves her bed. In addition, capture pictures of your cat when she's on her bed and upload those as well so you can keep tabs on her antics while you're away from home.
In this instructable, I'll walk you through the process of
* building a cat sensor out of a simple momentary switch, foam core and foam strips
* reading the cat sensor on your Mac or PC using Arduino and Processing
* automatically posting status updates to Twitter when your cat takes a nap or wakes back up
* taking pictures of your cat on the bed with a webcam and uploading the pictures to a webserver

Maybe when my husband wants a new project, I'll see if I can convince him to set this up for our kitties. In the meantime, I hope you enjoy the link and fat burner reviews. :-)
