Have you joined the chameleonforum.comToo much heat outside most of the year and a neighborhood full of friggin feral cats
Several south Floridians that keep their veiled and Panthers outside year round with fans and misters for the real hot days, above 90 or added heat to the outside enclosure for the cold nights or they bring them inside. That's where my info came from.
As for the cats, build the enclosure like chicken keepers build their chicken run. Hardware cloth with a skirt at ground level that goes around the outside perimeter and either gets buried or mine just lays on top and I used anchors to attach to ground. So far have kept out 3 cats, fox, and a coon. The mice are the only thing that can still get thru but they are only after the food.
