Unlike humans, cats don't have menstrual cycles and thus have no "menopause", and a female left to her own devices will have up to three litters a year, so it's entirely possible that many, many generations of Jellicles are alive at the same time. There can be plenty of inbreeding in a cat's ancestry, too. This means several of our fan theories could be true at the same time, but with most of the proposed parents actually being grandparents or great-grandparents or great-great-grandparents, etc., and with some cats being descended from several siblings and mating with close relatives.
