I don't know when did this, I just cleaned up his cage today and when I bought him outside I thought he just accidentally wet himself again with his sipper water bottle but it wasn't. （ｉДｉ）
Then I noticed this large black spot on his head and he had this small visible cut just beside it, I don't know what it is and I'm worried sick for him and I think he's having a hard time looking around because of it please help I wanna know what to do to help him and I couldn't find the exact words for it in the internet but its not really exactly it (;﹏
