I know! I'm not afraid of them, but I screamed in spite of myself. LOL.
It was a little bitty mouse.
The last ones I caught in my live trap pooped in it and it was sooooo stinky. I threw it away, so I'll have to get another one. TOMORROW!!
He's probably been in your house for a few days, and you've just now noticed him. So another 24 hours won't hurt anything. Leave a light on in your kitchen and he'll be less liable to re-appear. They prefer darkness, but as we all know, they often do come out when the lights are turned on. Yuck.
I'm not really scared of them either. I just don't like it when they suddenly pop out and run across the room, especially if it is close to me. *cold chill*
