As a joke, I’ll still say this. Mad cow disease was due in part to cows being fed some waste products including cow meat. I don’t think it’s a good idea for animals (mamals, whatever) to eat the flesh of their own species.
You’ve never forgiven me for that one, little, tiny act of cannibalism, have you? I mean, it was just a few people. And they were mostly already dead. Sheesh.
There is a similar disease in human cannibalistic societies.
