I am interested to know if there are other shelters or folks who have had ferrets with no other ailments suddenly develop sudden onset of kidney disorder-- even develop mouth ulcers within the last 3-4 months. We have had a rash of these outbreaks in locations of this shelter network -- and several ferret deaths due to it. I would like to have folks who have similar experiences please respond privately at the above email address. It seems it *might* be a food issue..?. we are conferring with other shelters who have had the same experiences in the last few months.. all using the same food and when switched the animals got better. Unfortunately our lack of knowledge , or expectation of this possibility, did not save a number of ferrets. Thanks [Posted in FML issue 3166]
