Fox shit is rare here in the city. More coyotes than foxes live here, actually. None can shit within a block or two, without me knowing about it.
If you frequent the lakes, you will sometimes find yourself amidst a half acre or more of goose shit. They clump themselves together in large quantities, graze along the shores, but guess what they all do just as they all take flight.!. Walking along, you step in it, then look around to carefully place your next step, very carefully, but can't find a place big enough for a shoe that does not have suddenly stinky (cuz you just stepped in it and broke open the coagulating surface) green goose slipperage.
It's more the sneak attack that gets to you. It smells like grass, until you disturb it.
