"Suppose the class members all happened to own pedigreed cats," the judge began, referring to the "class" or those filing the suit. "And the breeders who had sold the cats to the class members had told them that as responsible cat owners they would have to feed the cats kibbles during the day and Fancy Feast at night and buy a fountain for each cat because cats prefer to drink out of a fountain (where gravity works for them) rather than out of a bowl (where gravity works against them) and they don't like to share a fountain with another cat."
