It seems Wylla's been feeing a little better these past couple of days. She's been playing much more, and a little harder. Not nearly as hard as Audrey plays, but I can only think of a few kittens in our fostering history that could keep up with that girl.
She had some blood work done this week, and her white blood cell count is low, so that means she's still not completely out of the woods. But I take her current level of bounciness a sign that things are improving.
