First of all, I'm so sorry for the loss of your little girl, Princess.
I think rescuing another kitty to honor her memory is such a beautiful thing

I have a little girl but before her we had a little boy named Chester. In my experience Chester was a little more relaxed, cool, nothing seemed to bother him; Sophie on the other hand is a little more control freak and has more attitude.. but she's so darn sweet
But, as the other PT friends said, every cat has their own personality.

PLEASE, keep us updated, we'd love to stay in touch with you and meet your new kitty.

God bless you
