Black kitties have a special place in my heart, I don't know why, I just love them. (and calicoes) But this little Kelly sounds EXACTLY like what you need/want. I agree that she seems to have picked you!
I think if she is healthy she will fit in right away with you and the furbabes and Dan.
Open your heart to her, I am sure you will see cats of colors/kinds on Saturday, but I have a feeling with as generous and loving as your heart is, you will take Kelly!
And you are not blabbing on!! I love to read your posts!
