Prince William has revealed that his father, Prince Charles, is absolutely obsessed with a certain type of squirrel. “He is completely infatuated by the red squirrels that live around the [Birkhall] estate in Scotland,” Prince William told Country Life in a special edition of the British weekly guest-edited by Prince Charles himself. He added that the Prince of Whales likes them, “to the extent that he’s given them names and is allowing them into the house.”Prince Charles, who celebrated his 70th birthday Wednesday, noted that the rodents are “incredibly special creatures.”
