Mittens was such a beautiful, fluffy girl who loved you for such a long time. Her long life is a testament to the good care and abundant love that you showered upon her. Your heart is aching right now because your beautiful companion is no longer w/you, at least not in the flesh, but she'll always be w/you in spirit. And yes, you mentioned that you're a guy; at least I think that's what the word "daddy" means. Your generous spirit and soft heart tells us just what kind of guy you are, too. RIP, sweet Mittens and peace to you, daddy.
