Rat Wheels: Ratties love to play in Rodent Wheels. Make sure you get a large wheel, the larger the better. A hamster wheel is way to small for a rattie. One without the bars is far safer for a rattie. Some rat tales have been caught in the bars of hamster wheel. Also, ratties that run on wheel often have curly tails that come up over their back, I beleive this can be a problem for show ratties.
