moving her into a much larger tub is what most likely made her go off feed. moving her back might not get her feeding right away. I would clutter up the tub with crumble up newspaper for her to crawl under. making her feel more secure and when it's time, she'll eat. you can try feeding her in the dark, which will also help her feel more secure and hopefully going back on feed. once she starts feeding. slowly remore the newspaper one at a time. the key here is slowly. good luck don
