The gray hamster is a small rodent about 10 centimeters long. It lives in steppes and semi-deserts, digs burrows, and is active at night.
The gray hamster differs from related species by its short tail and gray coloration without bright spots. It helps nature by dispersing plant seeds and serving as food for snakes, owls, and foxes.
