That's a tuff one. Have you seen the set up at
www.dragonsdenherp.com ? Is that something like what you are needing to do ?
While surfing for cage/enclosure I had run across a pic of someone that took a rabbit hutch and modified it for their beardies. Adding nicely stained highgrade plywood and triming it out fancy. If i can find the link , i'll post it for you here.
We have to think "out of the box" on this one
have a good one, Rommie
