In using PYC from the 30 mg. "Healthy Origins Pycnogenol", to determine the dose by weight of the squirrel, multiply (4 x (?) the weight of the squirrel, then divide by the original wt. for the rats, 220, to get the amount of mg. of PYC .
For example: If the squirrel weighs 400 grams, then multiply the weight 400 x 4 = 1600, and divide the total by 220, which comes to (7.27 mg.)
Next, decide how best to divide the powder to get the closest dose determined for the squirrel which isn't always the same number depending upon the amount determined by weight. In this case, dividing the total powder into 4 equal parts would provide approximately (7.5 mg.) Since a tiny amount is lost in dividing this powder it should come out very close to the amount of this example.
I found that using the waxy side of a piece of butcher paper works well to support dividing the powder of the capsule using a one-sided razor blade, into equal portions.. Once divided, use a scissors to cut the paper in two parts, with the one portion on one side, and the excess portions on the other. From there, put a crease in the paper to funnel the left over powder into a holding plastic container for future use. For the one portion on the other piece of paper, divide it into two parts; include one half with the AM meal, and the other with the PM meal.
Again this amount is just an example, not necessarily what your squirrel's present weight is to use in the calculation. If you need help with this, PM me.
