I doubt the RSPCA would do anything They are only usually any good when the TV camera's are following them around Me personally I'd call the CPL to see if there is anything they could do to help with the Queen and her poor kittens Problem is though if their Queen and kittens happen to disapear by some miracle and be placed in good homes, they sound like the type of family to go out and buy another cat to start all this all over again
