Yeah i looked at that, both their ranges for requirements fit in with each other; BP's live fine with 60% which most terrariums fit that as their humidity levels and milk's are fine with that humidity. This is the advice i'm looking for you have given facts and evidence into possible reasons it might not work while not becoming slanted. Though snakes resort to cannibalism when there is competition? These 2 wouldn't be close to competing. (This doesn't apply to you) Why is everyone making this conversation as if i have the milk snake and ball python together right now? I don't plan on buying the cage like i stated. Plus i only own BP's which i plan on sticking with for the most part.
