We have found each of our wire cages work best by using a plastic dish washing drainboard to line most of the floor area. A littterbox takes up another part, and towels keep their little paws from slipping, scraping, or otherwise getting hurt on the remaining wire floor. Of course they use the towels for bedding as well. The local ferret shelter helped us find two used three-level cages. We just finished proofing them by covering all sharp edges with Avery plastic slidelock spines for report covers. The kids don't seem to eat them. Now we will cut flooring pieces for the upper levels from the indoor/outdoor carpet we bought at Home Depot.
