Honestly, it is much easier to keep them in racks.

I have an insulated shed outside for all my ball pythons and rodents.
The space heater keeps the room at a constant 80 degrees, the water bowls are perfect for humidity (which others use humidifiers).
A couple of proportional thermostats control the heat for the hot spots.
The racks and tubs make cleaning much easier than a tank or cage.

Sounds like a lot, but it is quite easy
