Steve wondered about feeding Marshall's and also about feeding a variety. When I first had ferrets (about 10 years ago) they came to me eating Marshall's. Many people on the FML at that time recommended Totally Ferret. After I slowly made the change, I noticed that their poops, while normal looking, were smaller and a lot less smelly. Also, at that time, Marshall food had a rather offensive odor. Perhaps there have been changes since then. Regarding food variety, I am reading that a lot of people mix high quality foods. It seems like a "Why not" situation to me. They get good food, the opportunity to choose, and exposure to other foods. Seems like a good idea in the event that one food goes out of production or is difficult to find. Shirley [Posted in FML issue 4515]
