A few days ago while scratching under Satey's chin, I felt a rough spot near his mouth. I was just going to bed, so I decided that I would check it out later. So later on I had my mom hold Satey for me while I took a look at it, and discovered what appeared to be a very large blackhead about the size of one of those balls on the head of a sewing pin (this is no exaggeration). So I got a paper towel and scratched the thing out, but I lost it in the process so I wasn't able to examine it further, but I do know that it was black and rough where it was exposed but was sort of yellowish white where it was in the skin. Immediately after, Satey had a gaping hole that was black all around (his skin is white). There was no blood or other seepage from the hole. It's closing up now, but his skin is still black in that area. This is the first time he's had anything like this, and there is no other signs of this elsewhere on his chin. The area was also not swollen or anything. Does this sound like a zit?
