I found a small growth on my cats back today. It looks like a large pimple. Its size is approx 1/16 inch circular and about 1/16 in tall, almost looks like a skin tag. Its color is a pinkish. It doesnt seem to cause discomfort for her. She only stays inside. She had a flea or 2 recently so I treated her with frontline a couple days ago. I didnt know about this little bump until today. I am worried about it. It feel is hard. Any help would be appreciated.
