I am sitting here eating my lunch...leftover mexican and a little tub of yogurt. When I start wondering who was the first person to eat yogurt. I mean really surely somebody had milk go bad in just the right way and congeal and they sniffed it, and said "this doesn't smell so bad" then they ate it. Anybody who has had milk go bad in the normal fashion wouldn't even touch the stuff right? Right so the milk must have gone bad somewhere warm, cooked almost. These things mystify me. Other food products less so... after all if racoons eat eggs, and a person say them...they might try eggs, especially since racoons eat other good things. But...I don't know of any animal that eats bad milk, at least not in the wild. Domesitcated animals will eat almost anything you stick in front of them, within reason of their digestive sytems.
