Hello Everyone; Has anyone ever heard of this? We opened up this liitle girl and there was no kidney-only a sac filled with urine. The left kidney was undersized. I have never heard of this before and I thought maybe somebody out there might have. The spelling I have may not be correct. Allie has crossed over to Rainbow Bridge. There was no choice, this was my friends ferret that she adopted a year and a half ago. I loved her too. Thank You, Mary [Posted in FML issue 2639]
