I figure I might as well comment on this. I feed my ferrets Iams and have had very good results. I'd likely be willing to switch to Totally Ferret IF I didn't have to throw out uneaten food after a day and worry about refridgeration. At least this was an issue the last I saw of the instructions as they didn't use any preservatives. I'm afraid preservatives isn't a nasty word to me. It means I know I'm feeding non-rancid food and have little waste at the same time. If Totally Ferret ever fixes this problem I'll likely switch but until then I'll stick with Iams and know that my fuzzies are still getting a good balanced diet. [Posted in FML issue 1572]
