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?
