This morning our vet asked whether I had heard of any extremely obese ferrets--not necessarily large, but extrememly overweight--that were younger than 18 months or so. Someone brought in a 4 pound male that is less than a year old. He isn't unusually long. He's somewhat lethargic, too. The suspicion is that it is a thyroid or other hormonal issue. So, I said I'd ask--if you have dealt with a situation like this, please contact me. Thanks, Jacqueline [Posted in FML issue 2901]
