The Mongolian gerbil, also referred to as the Mongolian jird, is a rodent belonging to the subfamily Gerbillinae. Their body size is typically 110–135 mm, with a 95–120 mm tail, and body weight 60–130 g, with adult males larger than females. The animal is used in science for research or kept as a small house pet. Their use in science dates back to the later half of the 19th century, but they only started to be kept as pets in the English-speaking world after 1954, when they were brought to the United States. However, their use in scientific research has fallen out of favor.
