I have a Marshall Mansion and I hate the set up as I do the Super Pet cages. I also have Midwest cages that I had raised 4 stray kittens in (that of course we kept). I found a wonderful lady, Karen, who has a patent pending on floors for these cages and what a cool idea!!! I happened to be searching all over the web for extra flooring/ balconies, etc for the Marshall Mansion and I came across something listed for ebay. I checked the link out and have been in touch with this woman (who has owned ferrets for 21 years) and I have ordered 2 floors to start. I cannot wait to get them and be able to fully utilize this cage! She hand makes these and here is the link to check them out. You have got to see these!
