Ferret droppings are black, thin and taper towards a twist at each end (generally produced singly but can adhere together in a clump).
Ferret droppings are 40–70mm long and 10mm wide, and look very similar to those of stoats and weasels, including the 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. Ferrets also make latrines (piles of droppings) at den entrances.
