Behind our house is our pasture. The field mice that live there have to dig burrows and supply them for the winter. I suppose some mice supply better than others. Apparently some think they have found a newer answer to all that hard work. They come to our house where someone supplies temperatures in the 70's, access to food, pillows and other things they can chew to their hearts content - no work at all, someone is taking care of them. Then they find the trap! If they can't get out of the trap and go back to the field and work, they're dead. Must be a lesson in there somewhere.
