Calculating dosages for small animals can be difficult. For example, 1 drop would be about 3 to 5 times your 0.0125cc dose, since a standard dropper (according to United States Pharmacopeia) produces drops of about 0.050 mL (from 0.045 to 0.055), or to put it another way, about 20 drops per mL. 1 milliliter (mL) = 1cc. They are two different names for the same thing. Usually medicine is prescribed by weight. That is, so many mg of medicine per kg of body weight. So generally, the trick is to figure out how much to give per pound of animal, then multiply that by your animal's weight in pounds. The average adult cat (splitting the difference between male and female) is somewhere around 7.5 - 11 pounds. An average ferret (again splitting male-female difference) is between 2 and 4 pounds. So if dosage by body weight is the same for both animals, an average ferret needs about 1/4 to 1/3 as much medicine as an average cat. Lonny Eachus [Posted in FML 7302]
