Reptariums are really not he ebst caging for ball pythons, and I would not recommend them. I debated on getting one for a BP in the past, but they are too open-aired which would make temperature impossible to maintain. Not to mention humidity. They do sell plastic thingies that cover the whole reptarium and are designed to trap in moisture, but it would be a lot more expensive than just buying a good sized rubbermaid or even an aquarium.
