We got Bob a little over 3 weeks ago. He is in a 41 qt tub with hides and water dish. Temp in warm hide is 90 - 91 cool side is 76 and humidity is usually about 76%...The day we got him the guy said he had a little smaller than normal rat. I gave him a week to get used to his new home them offered a fuzzy rat... He ate...waited another week and he ate again....then waited another week and he ate again (that was Friday)....so 3 meals with me and no poop... I have read this is normal....is that right?? He is fatter than when we got him....how long can he go? Tonight we let him take a little bath in sink hoping it would help...it didn't. He seemed to like being in the water but no poo... Also is 76% humidity all the time too high? I can add more holes in the tub if I need too.
