Hey All! If you ever have a chance to check out an excellent 2-book hand book called "Exotic Companion Medicine Handbook for Veterinarians" compiled by Cathy Johnson-Delaney DVM (Winger's Publishing), do so. It is an excellent compendium of information both for lay people and for vets on a large number of small animals and reptiles. The ferret section is great! I use the Exotic Animal Formulary also, but this volume is even better as it includes behavior, feeding, housing, ferret proofing as well as FFZ's, although some of these are out of date, but at least they recommend checking local laws. I don't know the cost in the US but I paid about $30 in Israel for the two volume set.
