Reminds me of a talk I had with my dad about 20 years ago. When I was stationed in Idaho we used to go out to the desert and shoot whistle pigs (Thompson ground squirels, kinda like small pararie dogs) there were hundreds of them everywhere during the spring and summer and I and my shootin buddies would take our guns (take my marlin .22 with 3x9 bushnell) and go shooting. We'd kill about 20 or so at a time. anyway my dad came for a visit and we were talking one day and one of the guys came by to see if I wanted to go shooting. We were talking and he said something like
"so what do you do with these whistle pigs after you shoot them"
"Huh, nothing, its just target practice really"
"oh, so you dont eat them?"
"Huh, no they're to small"
"so why do you need to kill these squirrels"
"well, they make a lot of holes in the ground and the cows come along and step in the holes and they can break their legs"
"Hmmm, sounds like fun, very sporting

"
(i think he may have actually rolled his eyes.) well it made me think. My dad knows I hunted, shot deer, duck, coyotes, grouse, and rabbits. but in all those cases we ate what we shot. I have a lot of respect for what my dad thinks and Lets just say that I decided not to use small animals I dont plan to eat as target practice, unless of course its a snake. only recently have I stopped to identify the snake before I kill it, cotton mouth or rattlesnake its gonna die, bull and garter snakes have free passage.
