Just passing it along for those who do not know - Zupreme is a brand that is well known in zoos and with veterinarians as being a top quality food. They make a ferret food that is 50% protein. Natural Gold ferret food is 60% protein. We recently changed our ferrets to a mixture of both and are quite pleased with it. We know they are getting the protein they need, as well as everything else. I owned a successful pet store in Louisville, KY for 11 years. Back in the day when premium foods were considered new, we were selling more than 2000 lbs. of Iams / Eukanuba premium pet foods a week. For those who do not know, premium foods always use the same 'recipe' and grade of product for each batch of food. Lesser quality foods may alter the recipe to include more of a product that is less expensive at the time or include a lesser grade of product if the price difference is too high. A high quality premium food is also generally going to use a better grade of product. Debbie Whorley [Posted in FML issue 4804]
