Aww - sorry to hear your news - She obviously has had a long happy life and - gosh I am filling up and I didn't even know her.
Take care - You did your best for her and I am sure that she would be grateful to you for helping her on her way.
I still believe that we will meet up with all animals that have been part of our lives and you will then meet up with her again.
Kind thoughts with you.
