For chocolate the darker it is the more risk it poses: <http://health.usnews.com/health-news/family-health/brain-and-behavior/articles/2010/10/11/halloween-chocolate-a-serious-threat-to-pets.html> In relation to the recall: http://www.fda.gov/Safety/Recalls/ucm228986.htm The reason I am sharing that with ferret lists is not only because ferrets also have trouble with too much Vitamin D (hypercalcemia leading to calcium deposits in organs like kidneys and hearts), but also because some people feed what they personally consider the "premier" brands of dog foods to ferrets or cats, though that is NOT a good idea since many or all dog foods will still be too low in taurine for ferrets or cats (so possible risk for hearts and eyes), the fat percentage is wrong, etc. 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."
