My rabbits have always been very healthy until now, they are brother and sister, were rescued when tiny and are now almost nine. The male keeps getting a poo-ey bottom end even though I am now cleaning out the hutch even more often. He is the most docile rabbit you would ever meet and sits calmly in the kitchen sink with his bottom exposed while I wipe and soak the stuck on bits to get them off his fur. The female lives in the same hutch and has a very clean bottom so it must be something he is doing, or not doing.
I'm going to take him to the vet in half term but I wondered if anyone has any ideas. I'm almost scared to take him as they are so elderly now that I worry they will find something wrong and before I know it they will be PTS. Unreasonable, I know, as the vet wouldn't do that unless it was absolutely necessary.
