Ok, I just built the cage from the cubes, I don't have my coroplast yet though. I built a cage 4 cubes by 2 cubes. I built a floor out of the cube wire also though because I wanted to be able to slide the cage across the floor once the coroplast tray is inside and not have the cube walls fall apart. I like it better this way, only, not I am not sure if the connecters on the bottom floor will raise up the coroplast too much or makes holes in the coroplast. Should I just take the floor out? I really wanted the floor, The pigs won't be sitting on the wire floor anyway because coroplast will be ontop of it. But I think the connectors might be a problem under the coroplast. What should I do? Also how big of a piece of coroplast should I get? The cage measures 29x53 I think. The biggest piece the store sells is a 4 ft by 8 ft sheet, is that TOO big or ok.
