Poss EC? Is the blindness in the form of white in the eyes?
She just seems to have everything old age related unfortunately She is going blind (or has gone blind) she's getting incontinent (she has been 100% litter trained since she was 8 weeks old and has never had an accident outside of her tray) her breathing isn't great and she has lost a lot of weight
Jane, she doesn't seem to be in too much pain when she moves, I think it's just all the signs of old age has she has always been a totally healthy bunny
