Bromadiolone, the active ingredient in Contrac, accumulates in the liver to inhibit and steadily decrease Vitamin K levels in the blood. This prevents the blood from being able to clot and will eventually lead to death. So the majority of the active is absorbed by the blood stream, and although very small trace amounts could potentially be found in the feces, it wouldn't be consistent. There will definitely be some of the waxy substance and the dye in it, but it wouldn't be enough to cause damage or be of any concern.
