For what it is worth--- my brother insisted on getting a hamster when he was about 10 yrs old. He never took care of it. It lived an isolated existence in a remote location of our house (because he couldn't stand the noises that the hamster made at night). I don't even think the poor thing got fed regularly.
That being said-- we did/do have a dog whom we all love and take care of. That poor hamster was just a bad match. We ended up giving the hamster and all his accessories away to my friend's little sister.
Hope you liked the story!
