He is only speaking the truth. A natural cage for a BP would resemble a termite mound in Africa. In fact, I daresay that my "plain" tubs, with 2 hide spots and a water dish, more closely mimic a termite mound, than a naturalistic terrarium that depicts a deciduous or tropical forest!
Whatever works though. Different strokes for different folks. But I would not want to see a snake stressed-out or suffering for human tank aesthetics.
