Aww I am so sorry to hear of your sister's beloved Shadow passing to the RB, it sounds like Shadow had a good life though, beautiful kitty reminds me of my lil Lexie, don't be afraid Shadow, Sooti and Romeo are there to greet you along with all the other kitties from PT, your life is only just beginning in Kitty heaven.

Condolences to you and your sister, it is such a sad time when we loose those we love so much. Hugs.
