I brought my five year old Jill to the doctor on January 31st along with three other ferrets to be checked for the second time after coming down with the flu. I have eighteen ferrets all together. During the exam Dr. Smith found a large mass on Jill so he suggested shooting an x-ray. What he found was her kidney swollen six times its size. The next day Jill went in for surgery and her kidney was removed. I brought Jill home the day of surgery to my intensive care unit (my closet) where she stayed for five days. Jill was the perfect patient taking her Clavamox without a fight, and eating her duck soup twice a day. Dr. Smith said he found where there must have been a blockage going from the kidney to the bladder causing the urine to back up and shutting the kidney down. Dr. Smith has no idea if it happened a week ago or months ago, but I was very lucky to have chosen her as one of the ferrets to be brought into his office that day. Has anyone else heard of this? And do you know what the prognosis would be after a surgery like this? Even looking back I can't see anything that would suggest there was a problem.
