i havent thought hard about this but i got a good idea for a cheap, easy, and comfortable cage idea, maybe some of you have thought of it or have it or have already realized that it's crap.
ok so first, for the bottom a large rubbermaid or other large tub to hold the dirt and be the floor, then build a pvc fram around the tub that can go over it and be lifted up or the tub can be a tray that slides out. then plexiglass (or wood) is attached to every side of the pvc structure except the bottom, the edges don't really need to be sealed unless its a small species that can escape. holes or even designs can then be cut into the plexiglass for ventilation with strong screen or some claw resistant material sealing the holes. i haven't exactly thought about the doors, i would probably have at least one on top and one on the front and would just cut rectangles from the plexiglass and attach them with hinges and door locks, possibly support them wih more pvc. with the doors the cage can be maintained and for good cleaning the bottom tray can be slid out and removed (scratch it, with branches, waterbowls, and other stuff this would not work) and the plexiglass/pvc caging can be lifted for a better cleaning.
please write back with comments,

P.S. just to clarify, the pvc goes on the inside of the frame so the sides can be as close to the tray as possible (maybe it can even be locked together) and they would be resting on whatever surface the cage was resting on
P.P.S. this is for my juvenile rudi
and just cuz i love this picture (and his expression in it):
