my female yearling ball yesterday when i was feeding her did something a little wierd she was sitting on one side of her feeding tub and her food was wondering around on the other side her tub is about 3ft long the mouse was nowhere near her and she went and struck but at herself and hit her tail.. hy fiance also said that she heard her hissing at her when she went into her cage but she hasnt done this to me yet is this just a case of a possibly mean BP or is it still adjusting to a new home ( ive only had her for about a week and a half )
