Our daughter is nine years old, going on sixteen. She decided that she wanted a ferret and began a very well organized campaign to convince my wife and I to let her have a ferret. She did tons of research, and used psychological tricks, played us against one another and several other very well planned out tactics to trick us into getting her not one, but two ferrets. (One ferret would be lonely and potentially more destructive during the day when she was at school - two ferrets would have each other for company.)One thing she did that was commendable was the vast amount of research that she did before we got the ferrets. I am a research kind of guy, and spent a lot of time finding just the right food for our dog. So she copied my techniques and did a great deal of research on the proper food.She learned that the ideal diet for a grown ferret is live baby chicks or live baby mice. This seemed impractical for our family, so we set out to find a better alternative.Enter the Wysong Ferret Epigen 90 Digestive Support - Dry Ferret Food. It appears to be the next closest thing the RAW Diet, while still giving them the proper nutrients that an obligate carnivore needs. Also, there has been some discussion over the richening of the "plain" Epigen 90 food, so the Digestive Support seems to be the better choice of the two.Our ferrets love it, and are growing and healthy and refuse most other (ferret) treats or scrambled eggs or other approved treats. They really like this food and it is working well for them. I recommend it highly.
