please don't be sorry you told this story, because I was so happy to read about it, and such a happy ending for this Tux, I commend your sister for doing the best she could and trying to help this poor cat, she could have easily turned a blind eye, as so many do, GOOD ON HER!!, and the most important part of this story is that TUX now has a good loving home,and that is what matters, nothing else IMO.
