Since I just realized that sheet metal probably rusts, is there anyway to get Linoliem sides to stand up on their own like a box or the coroplast? I want the cage to be like a 2 piece C&C cage, but by the looks of pictures, the linolieum looks perminatly secured to the grids. I'm trying to keep the cage cheap and simple. If all else fails, we'll probaby do a Bin cage, even though I really don't want to. Please answer soon, I'm going to adopt my 2 pigs soon, and need a cage!
