The best of luck integrating them, Claudia should have some maternal instinct and not actively attack a kitten, she may even mother it, and Vic will either totally ignore it or take it to his bosom and love it and hug it and probably call it George. I'm going by Sue's experience as a foster parent for the Cats Protection League. She ended up with 11 cats before she gave up , she had a wonderful success rate with raising very young kittens and taming down wild cats but she never really mastered the giving them back to the League for re-homing. All except one settled down nicely together and that one decided he would rather be an only cat and moved in with an elderly couple 4 doors down the street from her and was as happy as Larry .
