Weird animal feces found at home! Is it a pest?

I live in an urban, residential area in South America and today found these very weird, "twirly" feces, about an inch long, in the bathroom floor of my garage. (The feces actually kinda have a pretzel-like shape...?) I have no idea what creature could've made these. If it helps, I do have a garden with some wood chunks and a small bush laying around, but no big trees. There are also lots of cats that roam free around the neighborhood. And I found a small dirt hole dug right by a wall near the bathroom. Could this hole and the feces have been made by the same animal? I sure hope I don't have to call pest control.
