I'm not trying to be gross. Most animals I know sniff each other poop. To determine different things about each other.
I grew up around horses. Well I knew horse gather in a circle facing each other to determine who is who in group. By stomping there feet. Kind of like meeting who is top pony.
I was watching a show on horses. Stallions will go poop in area and then sniff each other poop to determine male matured.
I wonder when we live as cave people after a cave person took a poop. We went and sniff it to determine something about the other cave people.
Sure glad our nose became smaller and our sense of smell is bad compare to other animals. I heard us human are pretty smelly creatures. Look at our digestion
