you are spot on with the flagyl for c.diff, and that other antibx do indeed /can be a causal factor in actually precipitating contracting c.diff. how-ever, i know in humans, that C.Diff is very contagious, so am ASSuming that it might also be the same with ferrets. Your Vet should know re if it can be spread in their species. the probiotics are also a great idea in reclaiming the natural flora needed... again, not a vet, so would defer to those more knowledgeable there (Sukie!!! where are you!) good luck, and re the post on possible lymphoma /intestinal... sigh, anything is possible with these lil guys. dooks, michelle n the gang o 8 [Posted in FML 6758]
