I have a Leucistic Texas Rat that is having a terrible time shedding. I have been soaking her everyday for close to an hour and although some shed has come off along the sides of her body, it's her ventral scales that seem to be having the greatest difficulty. I have tried pulling gently on the stuck skin and it seems **really** stuck. I have added a large water dish to her enclosure for her to soak in. Any other alternatives or suggestions?
