Kelly I have only had my collareds for 3 days to and they [all 8 of them] do the same thing as you describe. They go to the cool side of the cage and chill out at around 73F under a piece of cork bark. This I feel is very normal because all of my desert speices do this wheather it is my australian dwarf monitors or my gilas and beadeds, remember one thing, if you give them a choice and they choose the cool side I wouldnt worry, if they remain in the cool spot for a couple of days then you may want to check them out for other problems by a vet. My theory is cool temps have never killed any of my reptiles but to hot has and so many people new to reptiles think they all love heat, truth is they need a heat source to utilize and thermoregulate as they are cold blooded but I have seen people cook reptiles way more then their reptiles die from staying on a cool side. People turn the cage into what I call a beef jerky machine and cook and dehydrate their lizards, smaller lizards will dehydrate much faster than the larger ones do. If you raise the cool side temps I would be very careful and truthfully I believe a cool side of 75F should be Max. for any reptile. As far as UVB light, well I could write a book on all of the testing and different bulbs I have used and tested with a UVB meter and all of the lights that are available dont live up to what they say they do. I will save that post for another time because my fingers are getting sore LOL

She spends most of her time basking, but I have seen her go to the cooler side and lay down for awhile. I will, however, increase the cool side temps and see if that helps her a bit.
I also know that she was not getting any UVB at the petstore and I bet that she was not fed as well there either. I hope, that with a little TLC, she will start gaining weight and of course, stop naughing on my finger. LOL
Thanks again for the help everyone!
