Good morning, Debbie, If your cage is 24" x 24" you can call or email Martin's (website: www.martinscages.com) cages for a plastic insert/pan (which is raised about 2" tall to prevent "accidents"). If the cage is about 24" x 18", a hardware store, such as Home Depot, or even a "Container" store will have plastic pans. Or you can use those peel and stick tiles. I would recommed, if possible, to put down a piece of wood before sticking in the tiles. With the cage I had two years ago, the "gunk" tended to seep through the cracks. I also had a ferret (or two or seven) who were great at pulling the tiles off the wire floor. Good luck Lise and Domi, Nonnie, Stacia, Dante and Cooper [Posted in FML issue 3065]
