I live in an old farmhouse that although refurbished, is to old to keep all the critters out. I heard a mouse (I hope) in my attic the other day so I set up a mouse trap. This is the third day in a row that I have come home to a mouse trap that is still set, but the peanut butter was licked clean! I have named the procosious little bastage, Jerry. My guess is it is a young mouse, and therefore is not heavy enough to set off the trap? I'm allergic to cats.....any advice? I'm afraid that if I keep feeding it peanut butter at this rate, I will simply help it grow to the Looney Toon size of a small kangaroo and it'll end up kickin my arse!
