The last time I went thru that, I got him in a trash can then slid a cookie sheet under and ran outside (in my nightie) to toss the little guy out. Of the course the door locked behind me and there i was in the middle of the street half dressed and trying to wake my son up to let me in.
My squirrel ate his way in thru a screen to get at a bowl of fruit.
Fun, No? Dude?
