We just came back from the vet. She detected a tiny lesion in her ear (probably from scratching her ear), and the vet said it looks like some bacteria have gotten into the wound and caused that reaction. Lily got an ointment into that wound and I was told it should have disappeared in a week or two. If not, I have to take her back to the vet.

BTW, Lily was such a good girl at the vet's! She ran into the x-ray-room twice and jumped onto the x-ray-machine. Obviously she thought it was a great cat tree!
