Let Sleeping dogs Lie (Together)

Recently we've noticed Tamber and Colin sleeping together at times. Until recently, if they were laying together it was because they both wanted the same spot (like the arm of the loveseat with a good view out the window). In the shot below, there's nothing special about that end of the couch, they more often prefer the other end. I think that they've finally reached the point where sometimes they sleep together because they actually like being together.
