What are these droppings from?

Asked January 9, 2015, 5:43 PM EST


I was wondering if you could help me identify some droppings we are getting in our bathroom. Everyday we find 5 to 8 small black droppings around the floor. They are hard, round on one side and irregular on the other side (as if the round part had been cut). We live in Bogota (12 °C night, 20 °C day).
What animal can it be?

Outside United States household pests structural and household pests unidentified droppings

you need better picture with higher magnification before we can even attempt some ID
