I was attending the 1992 American Academy of Forensic Sciences conference in New Orleans and a forensic pathologist related the following story (paraphrased as best as memory will serve): "Sometimes, when an individual living alone dies unexpectedly, several days may pass before anyone takes notice. Some of these individuals may own a dog or a cat, which will go unfed. In my experience, a dog may go for several days before finally resorting to eating the owner's body. A cat, on the other hand, will only wait a day or two. Just goes to show you which is more loyal. So, the next time you're falling asleep on the couch with the football game on, take a look at your cat. He's not watching you because he's enamored of you; he's checking to see if your chest is still moving." Oh, those wacky pathologists.
