There must be a mouse pandemic as well, because likewise, I've been having mice problems these past several months too . . . like I said, back in November I think it was, it was such poetic justice that I was watching MOUSEHUNT one night, and then just happened to find a mouse caught in a trap in the kitchen!
But seriously, I think just since last summer/fall or so, I've caught about five or six mice . . . just when you think you've stopped catching them since the traps aren't being disturbed, and you put the traps away and resume normal life, suddenly you start seeing droppings again . . . I think mice are smarter than we give them credit for.
