That is so wonderful. And I totally agree with the other post about her thanking you for caring for her. She knows that you have helped her. I have seen this in the past with two different cats.

And now I have had Mama cat for over 3 years. A couple weekends ago on a Sunday when I was watching TV with a friend Mama came into the room, jumped up into my lap and just gave me all kinds of loving. I was tickled. She never really purred either until after I had her for some time. Now she purrs big time.
