It is the most widely known species of the gerbil subfamily, and is the most commonly kept as a small house pet or experimental animal. Under those conditions, it is known as the domesticated gerbil. Like the Syrian or golden hamster, it was first brought to the United States in 1954 by Dr. Victor Schwentker for use in scientific research. Forty-four pairs were caught in Mongolia and brought to England. They were described as having "squirrel colors... with long furry tails."
