Ok, question. Ever since she ate the rat yesterday, she has been curled up in the hide at the cool side of the tank. Shouldn't she be at the warm side to digest properly?
She knows where she needs to be, don't worry. One comment on your feeding style, though - I scruff the rat with the tongs rather than holding the tail. It's rather unpleasant to be left holding the tail sheath if it comes off when she grabs it.
