Yes I have lost one to flystrike, and she was elderly and seriously ill. It was caught in the early stages and if she had been better in herself I believe she could have made a very good recovery, but she was very sick before hand.
I have kept rabbits for 12 years, as you know the vast majority have health problems and we have had numerous incontinent bunnies.
Yes I do feel terribly guilty about the one we lost but i try to tell myself that given the bunnies we have if I was that bad a bunny mummy we would have lost a lot more :?
No doubt someone will have a go about it which is why I didn't post about it at the time, but we really tried our best with her. If she hadn't been in such a bad state when she arrived then we may have had more time to help her
