Boas are not like ball pythons and do not stress out as easily. I keep baby boas in 2x1 cages or 28 or 32 quart tubs, then move them to CB70 or 3x2 cages, then to 4x2 cages. I only offer hides to baby boas. My sub-adult and adult boas do not get them, but I do cover part of the plexiglass, on the cages, to make it darker on the hot side.

Hope this helps.
