From your message, it sounds like this condition came on relatively fast. My money is on the abdomen: the signs point to this (enlarged belly; change in stool, radiologic signs, etc.). She may have peritonitis or other inflammatory condition of the bowel. Based on the age and signs there may still be a partial blockage-- but leave the diagnosis to experts who have actually examined the patient. RECOMMEND a SECOND OPINION ASAP with a knowledgable ferret veterinarian. Do not wait. Dr. H [human doc] [Posted in FML 6583]
