I could look for breeders for you, however, the roborovski's are the goldfish of the hamster world. The are extremly fast and not really handleable. You can stick your hand in their cage and let them run on your hand and that is about it. Along with that, they do best with the biggest size cage possible. Aquariums or tubs are good for this. Storage bins as cages
They also do best with lots of toys.
