Ok, this is just an idea I'm kicking around in my head at this point, and the odds of it getting done this summer are slim, but I am considering putting one together. I have a hole in the yard which has been a burn pit for brush and such, and I was thinking that with a rubber liner and very little ground work it could be made into a rather nice 6' or so pond. This would then be enclosed by a 8'×16' cage, constructed out of treaded lumber and 1"×1 " welded wire mesh. I'm actually thinking in terms of a solid wall 12" or so high above ground and at least 6" below. Top would be mesh covered too, for predator protection. There would of course be tons of climbing branches and shaded areas in the form of constructed shelters and giant half logs. All this is for my sulcatta, beardies, my aquatic turtles, my v. rudicollis, and whatever else I think would benefit from some outdoor time. Obviously not all at the same time, I'm just reptile crazy not stupid crazy. My question here is, do you think this will be adequate for the animals I listed and is there anything obvious I'm missing in this plan? All advice and input appreciated. Oh and the sulcatta is only about 6-7" so she can't tear through the wall I have planned.
