[Butterscotch2]

Okay, I have been checking Butterscotch out for a while and I have noticed a few things. One niple is pink and looks normal. but the other one is blackish and crusty. Is that normal or wrong? Also, one o her ears is clean, but the other one has brownish things coming out. Is it ear wax and normal? Lastly, all Butterscotch's nails are clear, except the right hind leg. It is a brown. Is any of this normal? Should i take her to the vet as soon as possible? Please help and thanks! Sorry, that can't have any pictures. My camera cann't take a clear picture that is so close to anything. Would anything cause pain to her?
