Can anyone tell me what this is? I just moved into a new house with another male cat, around the same age as mine. They have been getting along really well but playing a little roughly (it’s definitely not fighting). It was a bigger scab about a week ago, I assumed it was from the rough play. It’s slowly been getting better and it doesn’t seem to bother him but obviously I’m still a little concerned about it. I don’t think it’s feline chin acne because it doesn’t resemble any of the pictures I can find online & his chin doesn’t and has never looked “dirty” in any way, which I know is a sign of this condition. It’s been there for a little while now (about 1.5 weeks), maybe because the scab is constantly touched/hit when the cats play. I would really appreciate any thoughts, comments, advice
