On that converted hutch.....you can put full spectrum lighting at the peak, and for droppings, I custom made 3 pans out of cardboard boxes and taped the heck out of 'em (with packing tape) for water resistance. My dremmel came in handy, to drill holes in the plexiglass (which Lowe's cut down to size for free). And, you can make it a double decker by putting screen/hardware cloth on the "rails" that the original shelves set on. Anyway, was really cheap and a nice focal point, 'specially when it was decked out in greenery and mini christmas lights.
