We had a ferret come into the vet clinic where I work tonight. He is a two year old male that lives with 2 other ferrets. None of the others are sick. He does occasionally run loose and might have ate something he shouldn't have. Lethargic. Weak. Hasn't been eating very much in two days. Drinking lots of water. Owners says he was straining to urinate. Seemed very thin. Dehydrated. Huge, huge, huge spleen. Tiny bladder and he urinated all over the table and us! Rest of his abdomen was difficult to feel because he was so painful but no obvious masses or foreign bodies. Hair looked very thick and normal looking. Temp. normal. Did bloodwork. Everything normal but:hematocrit about 12 (very anemic), glucose 76(sort of a fasting sample since he hasn't really been eating and hadn't had anything prior to coming in tonight). Owner wouldn't keep ferret with us over night so we gave him SQ fluids and sent home. Will see him again tomorrow morning. Ideas? Enlarged spleen causing the problems? Foreign body we just can't feel? Insulinoma? Some other type of infection? If any of you have dealt with this sort of condition before or would have a suggestion, please either respond to the list or email me privately ASAP. Thanks. Beth [Posted in FML issue 2547]
