So my bun isn't eating his soft feces and leaving it on the floor or stuck in his fur. This has happened before, and at the advice of my vet I stopped giving the 1/2 cup of dark romaine lettuce he was getting daily (he said that mini lops can be sensitive to leafy greens),treats, and changed his pellets from a timothy/alfafa mix to pure timothy pellets. Throughout this he has been getting a constant supply of timothy hay as well. I did those things one at a time and eventually it stopped for a couple of months, but it started again when I tried giving him dried sweet potatoes as an occasional treat and celery as some greens. I stopped those when he stopped eating his night feces but it's still been going for a couple weeks. Should I change the diet again or is it some sort of bacterial issue in his gut?
