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.
