I swapped from custom cages ( made my out of plywood ) that were more less 2x2x2 cages they were ok but they seem healthier and happier inhe tubs now ( plus I got 21 snakes in the palce of what 5 would of taken in the cages.)

I made my own racks ( and I done have the greatest carpenter skills ) but between the 2 racks I ot build I can fit the entire collection on one wall in eh room and still have some extra room. The othe wall does house the 2 large custom cages I had built for my snakes ealry on ( stil they still good why trash them) but they only hold he boa (when she in it ) and my oldest rat and corn snake ( both could live in a tub just as happy.)
