Oreo is so cute and wide-eyed, but, Oreo looks more like a domestic rat and not a hamster. Hamsters have a very different body type compared to a rat. I had a rat very much like Oreo in my 2nd grade classroom. She was the children's favorite pet. The downside is they don't live long enough. Three years is old for a rat. It looks like Oreo has a great home! I'm glad you are enjoying her!
