When my old kitchen was being demolished I noticed that there were signs of mouse droppings in my sink cabinet, but no signs of mice. I also noticed that there were a bunch of gaps in the drywall behind the sink, and because of the… odd construction of this historical building it seemed likely that mice were able to occasionally get in, but didn’t stick around since they had nowhere to go.
Well, last night while working at the computer I felt something furry brush against my foot, and I looked down and it wasn’t Fiona. Then a few minutes later I saw something move out of the corner of my eye, and a little mouse peeked out from under my equipment shelving system and then scurried back underneath. (Fiona was, of course, asleep nearby and didn’t seem interested in me gesticulating at said shelving system.)
