Cornelius's poop?

I am told by the camp EMT that this fat ground squirrel lives under one of the camp buildings. We try very hard to make sure no wildlife has access to our food waste. But the plumpness seen here, and in springtime no less, is very suspect if you ask me. The EMT says this guy is called Cornelius.

Walking on  the boardwalk after the Cornelius spotting, I got to see even more of him. Or one of his friends. I think. I'm not actually entirely sure what squirrel poop looks like so I'm open to correction.
