Michelle, On your question of how much ferretone to give your ferret. I'd recommend that you not use mineral oil. I've been told that it acts like a laxative, and tends to coat the digestive tract so that absorption of nutrients is diminished. We dilute ferretone with Olive Oil. Two parts Olive Oil to one part Ferretone. Some use 3:1 or greater. Ours get a dose of one "pump" about 5 times a week. So far no indication of a vitamin A overdose. Dick B. [Posted in FML issue 0751]
