 Pigs do have their favorites and this is especially noted when one of a pair/companionship passes on leaving the other solo.  For those who observe pigs in a pile regularly, this face to face might be considered unusual.  My wife typically observes them side-to-side, alternating head to rump....apparently a probable survival tactic to monitor all sides of the sleeping passel in the wild.  In winter, you will find one or two cats curled up on top of some of the larger sleeping pigs as their body temp is usually over 100 degrees F (~40C).   Just now I hear 'Felix' outside the window, a large Yorkie, moving through the wild plum thicket.  Awesome crop this year and he will vacuum up loads of ground-fall with the others over the next week or two.
