Sad news this week - on Monday morning when I went to check on the bunnies, I found Mr. D lying in the pen looking like he was sleeping. But when he didn't move at the sound of the door opening, I realised we had lost him, for no discernible reason :( I had checked on the bunnies before I went to bed only 6 hours before, and Mr. D had been his usual cheeky self, bouncing around and putting his little paws up on the wire of the pen to ask me where his treat was (he knew that I would give the bunnies a treat every night when I checked them on my way to bed). So it was quite a shock and very upsetting to find him dead, with no clue as to what happened - he just looked as if he had sprawled on the floor in his usual corner and was having a snooze :(
