Lady the cuddler

In recent weeks Lady has become a super cuddler.  She has always been my shadow.  Where ever I rolled she was right there.  Now it has become more than that.
 
It is almost like she has a need for constant contact.  If I roll to a stop Lady slides her head into my hand.  If my hands are busy.  She will sit at my feet leaning into my legs.

Heaven forbid I should close the door while I am in the bathroom!  The clawing and crying are awful!

 Lady seems to be the most content in bed.  She knows where I am and she has her favorite pillow.  My leg.

Got any ideas what this is all about?
