I'm going to go with snakes, because I'm pretty sure they'd only eat stuff they've caught themselves. That said, if a zookeeper releases live mice into a snake enclosure, then you could again argue that the animal is being 'fed' and not really hunting. (Though if 'free' seagulls congregate for free chips at the beach, they are also relying on humans for food, I'd say. Ah, the conundrums....)
Anyway, under those definitions, living in a big city is going to limit my capacity to capture wildlife. Unless I can seek out some rats or birds, I suppose.
