All the kitties are so special but some of them jsut grab your heart and won't let go. I think Princess is the one that has done that to you. I hope she goes to a good foster home and won't have to stay at the shelter. You have done wonderful things for her and I'm sure she appreciates that she hasn't had to stay at the shelter.
I'm sure things will work out good for her...after all she has you as a Guardian Angel to watch out for her!
