I’d have thought a shod foot would do well enough. I all-too-vividly remember a couple of times when my dad had to euthanize an injured bird and mouse, and he didn’t give it more than a moment’s thought. I was horrified at the time, but man, was it quick.
He also once took the head off a sidewinder with a garden hoe when it was menacing me and my sister. I still have its rattle in a Bayer baby aspirin bottle somewhere.
Oops… we’ve derailed thoroughly, haven’t we?
