Indeed. In fact, pregnant jills were given 4200 units of vitamin A/kg/day day with no obvious effects. The recommended dose for pregnant HUMANS is about 5000 units PER PERSON (not per kg!). I concur with Dr. Williams that I was unable to find any mention of hypervitaminosis in ferrets in a literature search. Bill [Posted in FML issue 1065]
