I haven't got a photo unfortunately. Often I find animal poo on a small countryside road by my house in Northern France. The poo is long a bit like dog poo but far smaller - I'd say about 50mm long. It seems quite soft (unlike rabbit droppings) and seems dark purple in colour as though it's composed of the remains of berries of some kind. Would that be poo from something like a weasel? I assume fox poo would be larger. Local terrain is woods and pasture.
