Hi I'd be glad to hear any advice.
Well, I have a hamster right now, and his activity seems fine. A few days ago, I noticed a small patch on his head where no fur was growing. Now there is a little gray lump there, I think it MIGHT be getting bigger. Is this just a bump, or is it a disease or something? Please help if you know anything about these. thanks.
:huh:
It could be an infection spot, abscess, cyst, or tumor. A vet would have to tell you more.
