Awwww....I'm so glad they are getting along so well, and are finally cuddling. The 3rd picture is just he most adorable pic in the whole world.

It seems that Lily is learning her boundaries (she waited for Luna to wake up instead of jumping on her and being a bratty kitten), which could explain why they're getting on so well. Lily is a quick learner and Luna is a good "mommy."
