I got a new cat a couple weeks ago. She came from a shelter with a clean bill of health. Over the past few days, I've noticed that she's been developing some black spots on her chin that look a bit like acne. What's causing the spots? What can I do about it? Do I need to do anything about it?
I don't know if it matters, but she's an indoor cat now, being fed dry food. The shelter didn't know anything about her life before they got her.
The spots look pretty similar to the ones in this photo:
