We are very sorry to hear about your loss--don't try to second guess this, it only makes you feel worse. All any of us can do is give our fur-babies a loving forever home. Vet bills are very expensive and don't always get you a happy ending. Over the years, we have rescued 27 bunnies. When one dies, it hurts--a piece of your life just got stolen and will never be replaced. Be happy that your little baby knew he was loved and hang onto the happy memories. Larry and Nancy
