Cat dropping on pine needles.
Distinguishing features include: a series of elongated segments; 100-150mm total length; rounded shape in cross section; and approx 30mm diameter. In this instance, the pine needles give a good scale (typically 80 - 150mm long).
Cat droppings can be confused with those of dogs but remain dark in colour, like this example, whereas dog droppings often turn white and chalky.
