I didn't see it in your list, but my leo makes good use of her regular hides when she is not using her humid hide. I have one on the cool side and one on the hot side. I only use a UTH (with a thermostat), I would think that a UTH and a heat lamp might be a little much. Also put in a little dish of calcium for her to have at all times also (I use a top of a plastic milk container).
Good luck with your leo, hopefully she becomes a permanent resident!! We love ours, very interesting, amusing, and cute!! One of the only reptiles in my house that my husband actually likes, which is good..... he won't touch my snakes
. Hey and where are the pictures
