How sad you must feel, but remember that you did your best to help her, and she passed on finally knowing love, kindness and human touch. Her soul will always remember, and someday you may meet another kitty, and it will be her, coming back in feline form but maybe different coloring, to repay you tenfold. Blessings to you for trying to make the life of a feline better. Your deed will not go unrewarded.
