This shelving, as seen in the picture left, can be used to create either partial or full levels in your cage. Shelves are made from 1/2? x 1/2? stainless steel wire (aluminum laminate panels can be substituted for a significant cost savings, and framed in black anodized aluminum.) The 1/2? wire provides a good walking surface, allows waste to get to the pull out tray, and makes attaching hammocks easy.
