Ferret dropping (can be separate or clumped).
Ferret droppings are long, thin and taper towards a twist at each end. They are hard and black when dry and are often left in conspicuous positions (e.g. on top of a rock) for territorial marking. Droppings are typically 40–70mm long and 10mm wide. They can be curled, and will be full of feathers, fur, bones, or insect cuticle. They are difficult to distinguish from stoat or weasel droppings, but they will on average be larger.
