My 5-6 yr-old ferret, Jonas was silvery w black eyes as a kit, and then turned white. Over the years, he developed a small black spot on the top of his head and then later a black nostril. He has adrenal, and he lost almost all of his hair last year. The black spot on his head disappeared, but the black nostril remained. Now, after a Lupron shot abt 2 months ago, he has regrown his hair, including the spot on the top of his head, and the black on his nostril has spread. He's also got a new black spot a little outside one corner of his mouth. What causes this? Is it a normal occurrence? [Posted in FML 7602]
