Peace - for a few minutes

Last night Charlotte came down off the boxes, used her scratching post, then lay on the floor.  Marley was across the room, dozing near our feet.  He got up, walked over and lay down beside her.  (Massive jaw drop from both of us.)  He reached out with a front paw and touched her a few times, then settled down next to her.  It only lasted a short time before he got up and needed to go outside, but for just a few minutes there was peace that Marley initiated.  Progress?  I sure hope so.
