It's never happened to me, but apparently finding rats in your toilet is a thing. And here in the City, where we arguably have the largest collection of rats outside of Proctor & Gamble's research labs, it can be a real concern. This video from National Geographic shows how they do it.
A rat's ribs are hinged at the spine, enabling it to easily squeeze through the tightest spaces—like the pipes draining your toilet. And rats are great swimmers too; they can hold their breath for up to three minutes. See how quickly a rat can go from the city streets to your bathroom.
