I did not need to open the closet to see how the rat had gained access. After the beast had gnawed through the wall at the back of the closet it had proceeded to chew through the door as well. I found myself briefly wondering why it had come in through the closet. If it could chew through the wall it could simply have come directly into the bedroom. To need to take the extra step of chewing through the door seemed wasteful and excessive. I shook my head as if to clear out my ridiculous thoughts.
