It's not about what is best for my ball, because I will continue to feed her one prey item of appropriate size. I'm curious about the stomach of snakes, and if it stretches in only one direction, then how are cannibalistic snakes able to eat snakes longer then they are? And if they coil the other snake into their stomach, but the prey-snake was about the same girth, that means that the stomach stretches WAY more than the recommended prey item size.
One of the videos that made me start asking questions was on youtube. It was "cobra vs python" or something like that.
