Looks like a nipple to me.
Hi all,
I was just cleaning one of our Guinea Pigs and noticed this little black thing on his underside. I suspected a tick at first but I don’t see legs or anything on it. Is this normal? Kind of freaked out and nervous that there’s something wrong. He’s only 25 days old.View attachment 173187View attachment 173188View attachment 173189View attachment 173190View attachment 173191View attachment 173187View attachment 173188View attachment 173189View attachment 173190View attachment 173191
