For the last day or two, she's taken to lounging on the cat tree with her tail
wrapped around her so that she's covering at least one eye with the tail.  And
recently I've even caught her chewing the tip of her tail while up there!

I wish I could get pictures of this.  It's an instant Awwwwwwwww when we see
it.

Funny how such normal behavior is so gosh-darn adorable!
