Our baby possum plays chase around the house. She and True-love are both nocturnal so it works out well. Late last night I got up to find her helping with his weight lifting excercises. (He has diabetes and the weight lifting is part of his treatment). He was lying on the floor with Possum sitting up on her haunches and holding fast to his arm, with her little paws, as it went up and down. Really looked as though she was helping. Joy
