I have the same thing going on with my RTB. I have been giving a bath every couple of days. I treat the bath water and her water bowl with this stuff I got from the pet sotre to assist in hydration and to build his stomach up, after several regurges. I also just treated for mites on the little guy. I have been feeding small fuzzy's every 5 days, to try to build up his stomach (3 weeks so far). I know its hard not to kinda of throw the towl in, but so far what I am doing is working. I hoping to get him back on hoppers every 7 days soon. He is small anyways, 6 months old, 24 inches. I just wish I would have checked him better when I bought him. Hope this helps.
