According to my vet and the shelter here, both of whom always check up on what foods are best- Mazuri and Totally Ferret are the best, eukanuba kitten food is the best substitute if there is no good ferret food, and (err... sorry) they say 8-in-1 ferret food is total crap. Sorry, sorry, just offering what I know. I was feeding 8in1 to my ferrets and they didn't like it very much and when I told my vet what I was feeding them he told me to just trash it. Unfortunately I don't have anywhere to buy Totally Ferret or Mazuri so I feed mine Eukanuba. As far as I know Eukanuba is about the best stuff you can get with out ordering from a vet as far as dog and cat foods go. Plus my ferrets love it and they have the softest coats. Fuzzies are so cute! Also my mother tried switching her 2 puppies from Eukanuba to Science Diet and not only did they not like it but their pee-pee and poo started to get stinky :( Oh well, just my two cents anyway. Take care ya'll. Best wishes from me and the gang! [Posted in FML issue 3703]
