just like Tom and Jerry, only not as funny
    I found a dead mouse on the kitchen floor this morning.  One of our cats bit the little critter's face off.  It looks like the mouse came from a hole in the wall that I've never noticed before but which the cats have been guarding all morning.  I don't know how the mouse found its way inside, but I'm reminded of a something I learned in science class long ago.  There was once a theory (back when "science" was more drunken speculation than drunken reasoning) that claimed that organic matter could appear out of thin air, basically.  The scientist who made such a claim (and whose name eludes me) set out to prove it by making a mouse appear out of a rag that he stuffed in a closed bottle.  Needless to say, the experiment failed, and presumably the "scientist" went on to become a senator or president or something.  But I believe his theory is relevant in this case.  I can offer no explanation for this mouse appearance other than spontaneous matter conversion from the sheet-rock inside the wall.  
I'll make more observations later.
