as for getting a cat.. I'm not the biggest fan of them.. although I would get one if it would help. Problem is that they are only going into the cupboards from the walls. They haven't actually come out into the apartment. So I don't think a cat would have a huge effect.
I live by myself and dont' have a boyfriend so the thought of disposing traps drives me nuts. I did put one down that was covered and guts still leaked out of it. EWWW made me not want to try anymore traps.
Ideally there was only this one guy and I killed him. ha what are the chances that mice travel in ones?
