I am so very sorry about Miss Lacie...
I wish she could have shared more time with you, but like the others said, she left to the RB KNOWING that there was hope for her, that someone could and DID love her, and maybe that was what she needed to know that her life was finally complete ... that a loving soul (you) was willing to take her in and make her WHOLE life WORTH it. That was what she needed before she left. Again I am so sorry for you and your families loss. Take comfort in knowing that you were the one who completed her life. And was what made her such a special kitty to MANY other people. *HUGS* to you. :(
