Riley's end

Riley loves to sit in the doggie door with his hiney inside and his feet and head outside :) Usually this isn't too bad but with the weather we have been having lately this is a little bit cold to have the doggie door open like that :) But if I tell him to go in or go out he just gets back there and sits on his little doggie door seat happy as a clam...maybe that is so that he doesn't miss what is happening on the outside or the inside??
