I use something similar but homemade for my nearly adult cresties (the babies are in a Rubbermaid). I make sure my guys can stay warm enough by providing a colored bulb several inches above the cage that warms the fake foliage near the top by just a few degrees, and they will definitely thermoregulate by getting on top of that foliage or going to the bottom of the opposite side of the cage. Because it is so well ventilated, heat won't be trapped in the enclosure as it would (to varying degrees) in a glass or plastic enclosure, so a 40W to 60W bulb should be fine as long as the distance from the cage is sufficient.
As far as furnishing, the enclosure has 4 artificial plants of various types attached on a diagonal from bottom left to top right of one wall and stems arranged to provide cover and pathways from the floor to the ceiling and to the climbing branches that criss-cross the cage.
>>does anyone use these?? how do you furnish them? heat them? i keep my house right around 70-72 with a litle drop at night so ifigured iwould need some sort of small supplemental heat maybe a 40-60watt night bulb left on most of the time?? not sure any help would be great difficult decisions on caging. i would like to breed them eventually(on a very small scale) thanx
