Her weakness has since become her strength. One of her favorite pastimes is sinking her claws into the bark and racing as high as she can into a tree. It comes in handy too--she avoids rough "play fights" with her brother, makes the girls burst with laughter at her antics and has avoided everything from dogs to foxes who'd love to get their jaws on her.
I'm glad she's put her tree climbing skills to good use. I'm also pleased she's mastered getting down.
