My ball python will be arriving in two weeks or so, and I want him to feel as secure as possible. I have one of those steel racks from Home Depot for my snakes. After his quarantine period is over I was wondering if I should cover the sides of the rack with something (it's open on two sides)? I figure I could cut some cardboard and put it on each side (of the rack). He will be housed in an opaque sterlite tub so, is this necessary?
