Around 3am I thought I heard my 6 year old son fall out of bed but when checking realized the noise was coming from the bathroom. Something was moving behind the wall and under the tub from what I could hear and it sounded large. I flushed the toilet, knocked on the walls, and stomped around a bit. Whatever it is started snarling at me through the walls until i scared it off by banging and snarling back. Is this most likely a Raccoon/opossum? And what should I do next?
