When I gave Jimi a bath the other day I could see a large round spot on
his back about two inches in diameter.  At first I though it was grease or
something, but it wouldn't wash off.  It looks like it could be a bruise,
but he hasn't been stepped on or anything lately.  All of the rest of his
skin is a nice light pink.  The blotch is kind of a grayish color.  I never
noticed it before, but I suppose maybe it could be a birth mark??  Any
ideas or suggestions would be appreciated.  Should I be concerned?
 
Thanks a lot--Niki & Jimi
