Thanks for the link, the photo that that poster referred to is basically what it was looking like. Except I am really not sure that it is from aggressive grooming because she seems to completely ignore it. I do spend quite some time with them at night and have never seen her even lick at it.
Maybe I am blind, but I could not find the reference to spots.
Oh yeah, and if it matters, my girls are about a year and a half old, and neither have had any babies. I just don't feel experienced or knowledgeable enough to breed them.
