I have a short-haired male Syrian hamster, and he is about 3 months old. Just lately, I saw him itching and grooming like crazy. I'm quite sure that he is just grooming, but I need to be sure. Since everyone here is so knowledgable, I thought I'd give it a try.
Here is a short video clip of him doing this behavior. Thanks in advance!
