No, it's nothing obscene.
As I sat in my office at home tonight, I heard what sounded like people talking right outside. So, I got up to investigate and saw someone walking back down my driveway.
I started out to see what was going on, when I noticed one of these rat like animals. Rather it was two of them that I saw.
Knowing what the passersby had been looking at, I headed inside for the camera.
This one, and another of it's siblings, hid under my car while I attempted to take photos. I had to grab a flashlight to be able to focus properly in the dark.
In total, I saw 4 of these babies, and later, 1 adult. I saw the adult after I had gone back out to investigate the yip-yapping of a dog. I knew what the dog was barking at, but the owner mentioned that there was an adult too.
Anyway, this is the invasive species Myocastor coypus, known locally as the nutria. It also goes by the names of coypu, ragondin, beverrat, and castorino, depending on your location in the world.
