EW, EW, EW! As I'm sitting here, I can hear a mouse scratching in the wall. I don't know why, but for me that's even more sickening than seeing the mouse run through the room. We always get mice in the winter, and I think I'm at the point that I'm going to get a cat. We share a two-family house with my husband's parents, and I know MIL isn't fond of cats. But I just can't deal with having mice in my house this year.
Last year we had a mouse for so long, we even named him (Bruno). I wasn't working at that time, and I even came to know his schedule, when he would come from behind the couch, when he would go back, etc.
