There are mouse droppings in the cabinet under my kitchen sink. The mouse has has torn open a bunch of plastic wrapped bottles in the cabinet. We think that the mouse or mice entered through the hole surrounding the drainage pipe of the kitchen sink. The gap between the pipe and the wall is definitely large enough. One time, we even chased the mouse into the under sink cabinet, and when we opened the cabinet door, it was no where to be seen. So we think it escaped through that gap as well.
Question is: what am I supposed to use to fill the gap between the drainage pipe and the wall? Should it be metal grate? Or foam? Or what?
