Do snakes truly not know how large of prey are capable of eating? Shouldn't they be able to judge prey size? How do they survive in the wild? I'm a somewhat noob owner, and I'm terrified of feeding my snake something too large, and have been using the weight system (he's a baby still) to feed, because I'd read if you feed them somethign too large the rat can start to rot in their bellies or kill them. But then I see pictures of snakes swallowing VERY llarge prey and being fine - and pictures and stories like this where they eat something so large it kills them. How on earth do they manage in the wild?
