Squirrels!
We caught two squirrels; one in the barn and one in the house!  The red squirrel had been seen going into the barn for some time and the black one was heard in the attic for a few days before capture.  It would come down at night (probably via the wall between the long room and downstairs bathroom) and poop around the kitchen.  Both were driven down West Street and released.

The house squirrel would not be caught with the Have-A-Heart trap I found in the barn after repeated attempts.  I was obliged to purchase a smaller model which worked on the first attempt.  The barn squirrel was not so discriminating.
