Episode description:

This land is my land, that land is your land. Or so says the freshy pile of stinky excrement on top of the rock in the middle of the trail. For the more reclusive misanthropes of the animal world, their waste does all the talking. Whether it’s for sex, territory, or just to check in, animals can turn their 1s and 2s into As, Bs, and Cs. Learn to read the signs in the scat on this the Single Acorn Podscat.
