Sent in case Nell replied to the FML, too, since she misread. Some beef fat should be fine. Reread my post because I don't think that I had a typo. Avoid having in large amounts: UNsaturated fats (beef fat is saturated, not unsaturated) and fatty marine seafood Yes, I just checked; I did not have a typo and did write to avoid UNsaturated. What you SHOULD do is to pay someone with a doctorate in veterinary nutrition to help you. Websites and lists have a range of people. Some know what they are talking about and others just come out with complete clap trap that lacks having looked at both good and bad about their choices. So, go to places like: http://www.petdiets.com/ and get an actual expert helping you, Nell. OR use this recipe WITHOUT varying on it except for following a suggestion later made by Dr. Bruce Williams to strain the bones to remove any shards to better protect the esophagus, since many swear by Bob Church's homemade food: http://www.trifl.org/gravy.shtml Sukie (not a vet) Recommended ferret health links: http://pets.groups.yahoo.com/group/ferrethealth/ http://ferrethealth.org/archive/ http://www.afip.org/ferrets/index.html http://www.miamiferret.org/ http://www.ferrethealth.msu.edu/ http://www.ferretcongress.org/ http://www.trifl.org/index.shtml http://homepage.mac.com/sukie/sukiesferretlinks.html all ferret topics: http://listserv.ferretmailinglist.org/archives/ferret-search.html "All hail the procrastinators for they shall rule the world tomorrow."
