It was recommended to us when we purchased our ferrets that we mix Totally Ferret with Prozyme ("a natural enzyme supplement"). It's a powder we lightly sprinkle on top of their food and mix in. We have, for 2 1/2 years, fed them this combo. With all this discussion about too much of a good thing and toxicity in ferrets it got me wondering if this is a bad idea. However, so far they have been very healthy. Any comments?? Sincerely, Stacie and Rich Armstrong [log in to unmask] [Posted in FML issue 2377]
