Thanks, Polly's doing really well with her leg. She starts off with a hop and a skip but then walks fairly normally, and her leg is now a fraction shorter than it was, but this is hardly noticeable. Actually, my mum's cat (now passed away) was on cage rest about five years ago after a serious road injury to his leg and he didn't seem to mind one little bit, he adjusted to it rapidly, so hope yours is the same.
