Lucy Under the Tree

This is Lucy who is Sarah's cat, and she is a phantom cat!  There is also another cat, Oliver, and he is missing one front leg.  Oliver makes himself seen and will come over and allow us to pet him, but Lucy is mostly an apparition!  After spending four days or so in the house, Lucy could be seen peeking around a corner at us, and then would disappear.  By the last day, she would sit on the arm of the couch, with a wary look on her face.  At one point she spent some time in the living room, but only under the Christmas tree, peering out at the world.
