Hello!! I just upgraded to a Large repti breeze full screen cage and its for my lil female Jackson's cham. I just wanna know how to maintain heat alil better with out having to cook alive in my apartment lol she is sitting under 100 wat bulb and seems fine but every once in awhile she will climb all the way to the top and sit right under the bulb, she moves away most of the time when she gets to hot but I don't ever want her up there and getting stuck while im at work or something!! any suggestions!?
