Kelly sounds just darling, just the type of personality to make us dog people long for the possibility of a kitty in our lives. Your experience with Fawn (which I only now read about) had extenuating circumstances because of her UTI, and it did sound as if she was really bonded with and pining for Donna.

My fingers are crossed that Kelly will be the one you choose. I'm thinking that she will develop the kind of attachment for you that Fawn had for Donna.
