Did the rat stare you down in the corner with taunting squeaks, as if to goad you into playing a game? Haha.
They carry diseases though . I would probably have called an exterminator.
How do you think it got into your house though? If it got through an opening somewhere, you have more than one :eek:. If you think it came in through the door while it was open then you can probably just leave some traps, kill it, and not have to worry about it again.
