I have one of those cages at my mom's for when she ferret-sits.  I ordered
mine from Discount Master.  1-800-346-0749.  Cage measures 36"Lx24"Wx48"H.
It has a rolling bottom.  No slide out tray.  Has 2 ramps with 2 small
sheves.  It's pretty good.  I just don't like the shelves or ramps
construction.  Comes with a hammock.  Cost 135.00 +10.00 S+H.
