I decided to take Alice to the vet to make sure that there was nothing wrong causing her to miss meals. She shed on 2/14 and refused a rat on 2/15 even though it had been 2 1/2 weeks since her last meal. Prior to December of last year she had a very strong feeding response. Since then she has become very picky and eating every ten days on average. She weighed in at 2.23Kg today. I am waiting for her to defecate again so I can take that in to make sure there are no parasites. Other than that, she checked out just fine. She is hiding now and I probably will not see her for a while. It was not a fun day for her.
Also, I decided to switch the lighting I use for her. I have been using a compact florescent light from the start with her. I had read reports that some do emit UVB light. To make sure she is getting what she needs, I switched to a 2.0 series florescent light from Exo Terra.
