cats are sneaky and natural killers. they do kill just for the sake of killing but that is a separate issue. although indirectly related to this subject.
well humans knew the difference between wild dogs and pets for thousands of years. http://www.historyworld.net/wrldhis/PlainTextHistories.asp?historyid=ab57 I dont know but i see no reason to buy into this hype that is associated with the OP.
and that's why it was easy to sacrifice wild dogs. If they can eat them, how hard is it to kill them and bury them? :shrug:
