im gonna be building new cages soon. 2 or 3 for a rack. each gonna be 4x2x2. i think i wanna put a sandbox in just so they can have some fun and dig. do any of you do this? also i am thinking of putting screening over the top instead of venting the sides. that way itll vent, and i wont have to run my own electric into the cages? would that be enough ventilation? thanks for any answers.
