Is the one lamp on all night? If so then this could very well be impacting her sleep. The other thing you can do is while your up watching tv hook a black out curtain around the outside of the enclosure. Keep the bottom 6 inches open for air flow and do not cover the top of the cage. Then when you go to bed take it off. This will make it so it is much darker in the cage and you can still be up watching tv with the one lamp on.Yes, she's been more active during the morning, basking, eating. Because she's in my living room, I cut off the main lights and dim one lamp. So not total darkness. I've also added the mister and fogger in the past week. Perhaps she's not used to it yet? I can try total darkness tonight.
