Eating Pets After They Die?

I don't do this myself, but I know many people like to eat the bodies of their pets after they die. Of course, in the U.S. it's usually illegal to eat the kind of animal that would be considered a pet but not always. I have a friend who ate his pet chickens after they died (He didn't raise them for food. They lived in the house with them and after they died he'd eat them). How do you feel about this? Personally, even though I don't do it I still don't look down on people who do. After all, the pet is already dead. What are they going to do to hurt it?
