Fresh rat droppings are what color?

Explanation:
Color indicates how fresh the evidence is. Fresh rat droppings are black because they contain moisture and bile pigments that give them a dark, shiny appearance. As the droppings age and dry out, they oxidize and lose moisture, turning gray and eventually crumbly or pale—often appearing white in very old, desiccated material. So seeing black droppings suggests recent rat activity, while gray or white indicates older evidence.
