Prevue Hendryx Jumbo Steel Cat/Ferret Cage - 36x24x48

I noted it was heavy but that is a good thing construction-wise, but bad because the cage would have to be lifted to completely remove the tray (easier to clean out leaving attached). The flaws are that the pegs on the ramps do not all fit the holes on the shelves. They still stay in place, so I can ignore that, but it is sloppy manufacturing. Also, one of the doors does not close easily (they swing open from the side, but you raise/lower them to open/close...mine sticks when lowering). I imagine that probably isn't a common problem, though.
