Who Pooped?

Replica Scat Photo: N. Sincero 2011, Scat Wrangler: S. Sumrall
This scat can vary widely in color but is most often black. You might find scat from more than one individual in a pile. But you would not want to touch or even smell this scat, particularly because it may contain a deadly parasite.

I just noticed the dime, so I’m changing my guess. Rat.

The artist in me sees a Neanderthal face in profile in the upper right hand section of the scat.

Well done David (and Lori with your original answer)! This is the scat of Procyon lotor, otherwise known as a raccoon.
