We inherited a cat named "Purdy" when we bought our house a few months ago. Purdy is a female calico that has been spayed. She likes to spend a lot of time outside and sometimes disappears for quite a while. Yesterday she disappeared and wouldn't come to the door even though it was about 22 degrees outside. I'd love to have a GPS tracking collar for her just to see where the hell it is she goes to survive subfreezing nights. Of course she showed up this afternoon like nothing was wrong. I'm curious how that tracking collar has enough output for a satellite to pick it up. I wonder if it's a real product or not. Oh well, I can't afford one anyway.
