Hi I am looking for advice. Went to let one of my pair of rabbits out for his daily exercise today and he was sitting huddled up. He never left his hutch although the female partner did. Normally he binkies up and down so he obviously is not well. He has not eaten all day. I recently changed their foot from Wagg Bunny Basics over to Allen and Page and although all of my six rabbits have been eating it I have noticed they have all lost a bit of weight especially him???? I am very worried now.
