Djungarian (Siberian-Winter White Russian Dwarf)

The Djungarian hamster (Phodopus sungorus), also known as the Siberian hamster or Russian winter white dwarf hamster, is a species of hamster in the genus Phodopus. It is ball-shaped and typically half the size of the Syrian hamster, and therefore called a dwarf hamster along with all Phodopus species. Features of the Djungarian hamster include a typically thick, dark grey dorsal stripe and furry feet.
