I have two Midwest cages with the "remodeling kit" from Kritter Koncepts.
( www.kritterkoncepts.net) By the time you buy a couple replacement
shelves and ramps you could buy the kit. It consists of three floors
with connecting ramps, made of heavy vinyl coated cage quality hardware
cloth. 1/2x1/2". The ramps can be hooked up to close off a floor to
divide the cage if you want, and the ferrets get actual floors. I did
have trouble with the size when I sent for one so be sure to send acurate
inside measurements. You get to install it with cage clips and once in
place the cage does not collapse. I have kept as many as 6 ferrets in
the cages this way.
For the floor I replaced the original trays with plain flat trays from
Martin's Cages 24x36 Dura-tray. I found they must be set of a solid flat
surface like 1/2" plywood on a table to support the weight of the cage or
the cage will push it down and out of shape.
