What you don't want is more than one mousie 'cause then you go from 2 to 20 faster than you wanna think about. Get thee down to the hardware store and get some traps (hav-a-heart have worked well for us). They like peanut butter a lot!
I agree with all of this!
It is definitely mousie poo, unfortunately, but it shouldn't be too hard to remedy the problem with some traps and a watchful eye. I agree that it looks like just one mouse (for now) but that can rapidly change if he starts getting too comfortable.
Can you borrow a cat from someone if you don't have one of your own? I know that sounds nutty, but we've loaned our cats out on occasion because they are such good mousers. When mice see a cat lurking around they will often pack their bags and go elsewhere.
Also, while you haven't see active evidence of the little thing anywhere else, you should still be vigilant about putting food up and away, clearing up crumbs, and storing your food in pest-resistant containers (glass or metal canisters work great). If they can't find anything to eat, they usually won't stay long.
