A female, and certainly a male, can live their whole lives in a 4x2’ of any height. They are ground dwellers and although they can climb, spend most their time hiding and feeling secure.
For the same reason I said 4x2’x15” for the MBK - easier to clean than a 4x2x1’, I would get that.
A 4x2x2’ for a ball is overkill. They will barely use the height and it will cost more to heat.
