Caught our fourth mouse last night.
Two nights ago we spent 45 minutes reinforcing the perimiter (by that I mean that I was on my hands and knees behind the stove & refrigerator poking steel wool into crevices around the baseboard while my roommate handed me things from behind the DMZ). Hopefully this means that this little guy was trapped in and we caught him, not that he somehow snuck in.
I let him go this morning into a snow bank at Central Park. Good luck, jerk.
