I've had critters come back to life. Mostly birds, but my wife once shot a deer with a slug in a river bottom. I went to check when I heard the shot and found her gloating over a small buck. It was in a bushy swale, laying back in the bottom with legs slightly elevated. There was a little blood in the snow by its head and no visible wound. Taking my knife, I went to the task but felt something was off. I put the knife in my left hand just as the buck's eye popped open. We made eye contact and he went nuts. I was behind him but only about a foot away. I used the occasion to practice my quick-draw. When I rolled the dead deer over, I found that my wife had shot off one antler right at the base of the skull, where there was some slight bleeding. Otherwise, the deer was entirely uninjured. I saved the shot-off antler and still have a lot of fun ribbing her over the event.
