This video has been all over the Internet. A guy in Peru posted video of a rat taking a shower in his sink. The rat's lathered-up, standing, and scrubbing itself like a human.
But there are a couple problems. First, it's not a rat . . . it's a pacarana, a different type of rodent from South America. And more importantly, some animal experts think it might be "showering" because the soap is bothering him or even PAINFUL.
