I don't have enough grids left so I was thinking of putting my old store bought cages top on top for a second level and just take one grid from underneath off and adding a ramp. NOW the problem is that I dont know what to use for a bedding holder. I can't use rug or towel because my dad says it smells. And I dont want to use the cages bottom because it looks tacky. And I don't have coroplast or vinel avalable at this time. What should I use for an alternative?
