In this one, I love how she works so hard to stay on the ball, then loses her balance, crashes on the floor, and gets right back up on the ball again.
She's been rewarded so heavily for interacting with a pilates ball, that now all you have to do is out one in front of her and she jumps right on it.
Here is another video of Star amusing herself with a rope toy.
Suffice it to say for now that Star has had some very good news! And not just that her Pilates skills have grown by leaps and bounds.
