I have not tried the wysong ferret food, I didn't know they made a ferret formula. I feed my Papillon the canine diet and have been very pleased with it, she loves it to! I will have to see if my distributer can get some for me, her prices are a little bit cheaper than the website prices. I'd love to hear if anyone has fed it to their ferrets. They also have a Feline/Canine diet, Archetype, that they say can be used on other carnivores such as ferret/mink/zoo species. Its about the same price. Thanks for letting us know they make a ferret formula! ~Jamie~ [Posted in FML issue 4421]
