Poor Fluffy. I think he crashed into the wall just one too many times....he had the room completely sorted but he was out with a friend and must have got over-excited. He did crash but not as hard as he has crashed other times. He was fine and continued to fly around and we put him to bed, but the next day he was feet up in the bottom of the cage!! Poor little guy. I had a very upset 8 yr old that morning We miss him.
