I have a ten year old albino female ball. She has been soaking in her water tub for the last three days during the day. She goes back into her hide around six in the evening. Her feeding has been irregular for a while. She last ate 8/1 and 6/21 prior to that. The temp under her hide is 89-90 and 84-86 where her water is at. She doesn't have mites or any other visual parasites. She last shed 7/6 and is housed alone. Please provide any ideas.
