I just read something very interesting in a book titled 'Dolphins' by Chris Catton, 1995. "Captive dolphins have often developed gastro-intestinal ulcers, a complaint usually associated with stress in humans, and postmortem examination often shows them to have enlarged adrenal glands, again, generally taken to be a sign of stress." Just something ferrets and dolphins have in common. [Posted in FML issue 3479]
