green poop pile
Except for the color, it most resembles porcupine scat. Those rodents often make huge piles of droppings in front of or in their dens.
There is a good image that contains an image of a similar scat pile at
I agree with Dave. The color all depends on what they have been eating. I've seen porcupine scat in a few reference guides look green like this.
Thank you so much for the information!!!
