So, my dearest Fluffy Guinea pig ended up with mites from the immune system stress caused by getting attacked by Ron. He was crying in pain all the time, and I felt so bad for him…

After doing a lot of research, I ended up getting Bag Balm to spread over his wounds. He cried until the soothing effects took over, and now, a week later, his wounds are improving, and the scaly parts if his skin are flaking off, showing new skin.
