Hamster`s don`t notice interior or exterior design so I wouldn`t use anything unsafe just to make the cage fancy at the expense of the hamster`s health or switching the cage which can cause stress to a hamster. Someone (I think it was Gazmo?) recently bought some sticky-back-plastic in pink and animal print design and put this on the outside of her cage and because this is instant, the hamster doesn`t need to move out!
