Does anyone know of a website (or store) that sells just the bottom tray for ferret cages? Regardless of what we do, our metal bottom has a spot of rust (guess the boys miss sometimes!). We've tried lining it (new dig toy), putting down tile (won't stick to metal), etc. I am looking for a plastic bottom instead of a metal replacement. My cage is custom built, but the manufacturer only deals in metal trays. Thanks!! Jen and Gang [Posted in FML issue 2851]
