Hi. Has anyone had any experience with ferret obesity, if indeed it exists? My husband and I are beginning to be concerned with our MF ferret (Harriet). She is a possum- faced/white mitt ferret who isn't nearly as active, playful and skinny as our masked ferret. She is not listless, just lazy and always wanting treats. We drastically cut down her snacks of dried fruit,, but she seemed to fill the 'gap' with extra IAMS cat-food. We became more concerned when she couldn't fit through a cardboard tube that she has always enjoyed playing with. Also, she is quite the noisy sleeper--we wonder if she is having trouble breathing. Is there any way to measure if a ferret is too fat for it's own good? Any advice is appreciated. -Cindy [Posted in FML issue 0816]
