My gripe is that NO those screen cages are not ok for Monitors of any size (regardless of being in a temp controlled room), Blueys do not belong in racks and IMO neither do leos or beardies. Monitors, Tegus, Blueys are all very intelligent species and they need room to explore. I'm so tired of people saying bare minimum husbandry is ok because its a "high yield" breeding facility. Husbandry doesn't get a pass because they are breeders, and I am not just targeting him at this point. Lizards explore, they don't sit in burrows all day, they cover a lot more ground in a day then snakes, esp monitors, none of them belong in racks.
