if there in a rack they prolly be ok without one but in glass i would use one
at night i cover mine with towels and my big girl will come out and hide behind the towel as long as theres not alotta foot traffic they prolly wont stress to much, i would use a hide even in a rack though but i take em out when im going for a lock up
i make my hides outa baskets though, they look cool snakes seem to like em
and there uber cheap at any walgreens or value village (they still have VV,s?)
50 cents a peice for my last 4 lol and if they get tatterd or overly pooped in
toss em and buy new ones!
i even run em thru the dishawsher a few times and they hold up really well
