About cages: I made my own for my two ferrets for about $120.  Sound kind
of expensive?  Listen to the dimensions...36" x 29.5" x 75"...  That is
right, 6 feet, three inches tall.  Four FULL levels...completely floored.
(No half-floors for fuzzys to fall through.  I also put doors on all four
levels and even put a door on the back of the first floor for ease of
litter box maintenance.  I could even add another door to each of the other
levels for ease of access, but haven't felt the need to do so yet.
 
   Material list (all bought from Builder's Square):
        wire cutters
        tape measure
        5/8" mesh green plastic-coated garden fencing
                (It comes in a roll that is 36" wide by 24 or 25 ft long)
                This will be the walls of the cage
        1/4" mesh wire cloth (2 or three rolls)
                (Comes in rolls that are 36" wide by 6 feet long)
                These will be the floors and ramps
        Plastic tie-wraps.  About 1000 small ones.  Came in packs of 100.
                I bought some...disn't have enough...bought some more
                ...etc, until I was finished.
