While I hate to be hitting the same note over and over again, we are just beginning to understand how common IBD in ferrets is, and a previous history of ECE is probably the most reliable indicator of IBD in ferrets. Plus if only one of the ferrets has it, it points to IBD. Has your vet discussed taking an intestinal biopsy? You may want to examine your recipe for ingredients that may be contributing to diarrhea. Many recipes contain a lot of nutrients, but not all of them are appropriate for animals with diminished absorptive capacity. With kindest regards, Bruce Williams, DVM [Posted in FML issue 3845]
