I live in a fairly rural area where 80% of the people hunt. I would predict that all 'loose' game from house cats to deer/elk would disappear within six months. The mighty local hunters would collect the best cuts and waste the rest. Anyone with a cow or goat or chicken would do best to keep it in the house, or sleep in the barn with a gun.

Eat the relatives you don't like first.

John Steinbeck (from Travels with Charley): "If I were hungry, I would happily hunt anything that runs or crawls or flies, even relatives, and tear them down with my teeth."
