I don't know if this will help but I have two of the large Midwest cages but I don't use the floor panels that came with them. I went to the local lumber co. and got 1/2" plywood. I cut the plywood to fit the inside of the cage about half-way up from the bottom. One cage I turned into two cages (upper and Lower). In the other cage I cut a section of the plywood out to fit one of the ramps so they could go from the lower to the upper level. I covered the plywood with linoleum and drilled holes around the outer edge and used nylon wire-ties to hold the plywood in place on the inside of the cage. The fuzzies seem to like the floors in the cages and have twice the floor space with plenty of room for hammocks, litterbox ect.
