Help. Not sure what this is and how long it has been there. It's a circular hard thing that has some purple color around the bottom part of the circle. What the heck?
A hard lump on the abdomen in a female cat, especially if it is in the mammary chain (line of nipples) is worrisome for mammary cancer. It could be something benign, too, but pictures won't be conclusive.
It is only on the skin...not under the skin. I just rolled it around in my fingers and it was just in the skin. I have a picture on my cell but I don't know how to get it in this post.
