Alert - poo picture in post! Identity needed

Yes, cheap laugh..sorry

Too pale and consistent to be a wild animal I think.
Most likely a dog. Must be a gap in your fence somewhere.
The only wild animal that could poo that size would be a fox or a badger and it’s neither of those.

I've seen a lot of fox poo and it ain't. Fox scat typically has a "point" - formed by the fur of mice and rats etc which are in their diet.

This is very like the droppings of a dog that has a lot of lime in its diet, from bones, or some kind of special food.

Cats do bury theirs and its usually softer and darker than this.
