I would say get a rat. They are the best rodents. They are better then hamsters b/c I've found that they love to be with people and rarely try to run away. And another bonus is they are very smart and don't bite.(the only time they might bite is when you first buy it)

I had a rat named Rocco and he was the best. He even gave my kisses like a dog. and he didn't try to run away I could sit in the living room and let him run around and then i would call him and he'd come running. They really are the best
