If you want to show her then don't let the potential loss of points put you off. Sometimes a hamster can still end up doing well if the other criteria are top notch and I think it's still fun to enter and go to the shows.
One of mine has won his straight class in the main show despite having several noticeable moult lines (common at this time of year but still a fault) because he recovered the deduction for that in the other criteria. A loss of a couple of points doesn't necessarily mean that they won't come home with a placing.
