Finally, Cath managed to find a spell in Hannahbelle's book that allows to have a human appearance, unfortunately, this is only partial. She will keep those polar bear ears, a tail and a few claws. The worst is that it will not regain her normal weight, before become a polar bear.
Most important for Cath is that she can become human for some occassion.
