A sparrow when i was a kid with a slingshot, then there was a long lull until one day i threw a stone at a wooden fence, i hit it alright, the stone bounced back bringing with it a sparrow i had not seen in the shrubbery in front of the fence.
Lately just rats with a airgun, and thats not much as getting permissions even from places that are crawling are impossible for some strange reason.
I was also as a kid accused to shooting at caged rabbits on the local playground, of course i would never do something that demented, actually i was hiding behind the rabbit cages, and we kids was shooting with DIY bows and arrows at each others legs,,,,,, and some times the blunt arrows did penetrate the skin. ( no one lost any eyes )
