She is a dominant spot Chinese hamster Louise. These pics are much clearer than the original ones yu posted and I was hesitant about those as you could only see her face and you seemed sure she was a Russian.
Chinese hamsters have a little prehensile tail which they can curl around things and hold on with. The are really gentle and make lovely pets. We have a boy Chinese.
Mice and hamsters cannot be crossed but the Russian Campbells and Winter Whites can as they are so very close genetically.
Hope you enjoy your little Chinese Hamster.
