We think a red fox keeps defecating in our backyard even though it is completely enclosed by a high fence. The fox keeps leaving the poo right by our back door. Every morning I have to check for poo and go out and scoop if it is there. There are lots of clumpy brown things on the back porch and I think most of them are mud, but some could be fox poo. Guess I'm more used to dealing with mice and cockroaches.
