Is this the person who was going to take your black kitten and meezer kitten? I think that like you said you should offer her one of your older rescued cats that is already declawed if she feels she needs a declawed cat! It is sad how many declawed cats end up in shelters and rescues. You also might want to have it in writing somewhere when screening potential adopters that cats must not be declawed! You could also mention softpaws if they are worried about their furniture.
Good luck Kim!
