Emergency: Most likely fatal diarrhea in domesticated rabbit
We recently had a few-week-old Himalayan rabbit pass away from diarrhea. Nothing we did helped. Also, an abandoned Florida White rabbit adopted us. It dug into our rabbitry, so we put out water and food (Purina and Calf manna). The F.W. would come in normally, when no one people were in there. Yesterday, he came in with hardly any movement in his legs, unable to eat or drink on it's own, and the worst dysentery that I've ever seen. It was like scours on piglets. The baby had died, but none of the other six babies, nor the mother died of the first case, but this one is also appearing fatal.
Has anyone had this problem, and if so, what did you do? He and I are running out of time. Please advise,
