Yea, definitely try asking on a rat forum. The dosage of 2cc (1 cubic centimeter = 1 mL) implies it is talking about a fluid dose, not a pill dose. One of the important rights of medication is right route. You can't use an oral medication as a SubQ or IM dose.
There is a BIG reason I love the metric system. Most medications are measured in that way, such as in miligrams per kilogram (or micrograms, etc. whatever unit of measure per kilogram). That makes it MUCH easier to calculate a dose for even a miniscule animal, such as a rat who is weighed in grams (30 grams per ounce), since there are 1000 grams in a kilogram. Sure, there are still some archaic medicinal weights such as grains, but those are few and far between (except for when it is used for aspirin, but it is always seen with its mg equivalent).
