I know that when you take a cast off of us two legged family members it takes a while for it to feel 'right' and also it almost always STINKS! So it sounds to me like Katie is going to be just fine. Remember that her leg hurt her and then was really stable with that cast - even though it started hurting her as well.

Nothing but good thoughts for you all from my family to yours!

She will be fine - patience.......
