You might be surprised to know just how often deer and other critters are harvested due to convenience and/or circumstance. Living in rural America for the majority of my life, I and most of the folks that I know have done it. Squirrel and dumplings, because you had a .22 while cutting firewood, is a good example. When you haven't filled your deer tag yet, and one walks across the drive... its pretty normal for a lot of folks.
Good job with your "grocery shopping".
