Making the Best of a Bad situation

As I wrote previously, my brother and SIL's dear cat,  Bob, is recovering from heart failure, and I wanted to share the inventive solution they have arrived at to help Bob cope with not having the use of one foot.  Bob was dragging his foot and had worn off the fur and begun to scrape his skin, so my cycling enthusiast brother, made a foot cover from a used bike tire.  Each morning, Trish puts on the "shoe" and Bob heads out to his much loved garden where he holds forth all day.  So far he seems to be healthy and has made an incredible adjustment to his disability.
