http://www.smartgroups.com/message/readmessage.cfm?gid=1423922 &messageid=5113&startid=5118 t sounds like your male may have Inflammatory Bowel Disease (IBD). This is a some what common problem in dogs and cats, so most small animal vets will be knowledgeable about this disease. Some case respond to pred only, but some cases need Imuran to control the diarrhea. Hopefully Chris will be able to direct you to a ferret vet there in England. Hope that helps, Jerry Murray, DVM [Posted in FML issue 4188]
