I am ceratin that this is a topic that has been well addressed that I have missed, but with the combination of an ECE digestive system damaged ferret this seems to be a very big concern. Several months ago we faced an ECE epidemic in our home with one ferret continuing to need extra special atttention and feeding. With hand feeding and the addition of extra fsupliments and a higher fat conent we were just starting to get some weight back on her frail body. The flu hit our home about 5 days ago and the combination of the flew with the intestinal damage was all that she could take and we lost Nicky Bear within 48 hours of the onset of the flu. There seemed to be no amount of food, eletrolyte and liquid consumption that could replace what her system needed. Perhaps i am a bit out of touch,,, but has anyone to date an understanding of not the syptoms but the nature of ECE? Hal, Jessica, & Justine and our 3 surviving ferrets [Posted in FML issue 1352]
