Alfie Wagtail is a clear winner for this post. Day by day he becomes more and more part of us and our lives together. He lives to play, has boundless energy, unfathomable affection, is never happier than when we three are together in the same room, yet he has an indomitable spirit and a bit of the devil in him. He’s a treasure.
