I'm really sorry if this is dumb and it's just his nipple or something. But, we noticed this spot on our cats lower belly area. He's a 2 year old male, gray and white. We haven't noticed him scratching this area at all or anything, and he's been acting normally. My husband thinks it's just his nipple, but he doesn't have any other spots that look like this. It's maybe about half an inch around. Thank you for any answers, and again sorry if this is a dumb question!
