The Mongolian gerbil is a small rodent native to the deserts of Mongolia and northern China. It typically measures about 4 to 6 inches in length, with a long tail that can be as long as its body. These animals have soft fur, usually in shades of brown or gray, and are known for their large, expressive eyes and long whiskers. Mongolian gerbils are social creatures that live in burrows and can be found in groups in the wild. They are popular pets due to their friendly nature and low maintenance needs. In captivity, they require a spacious cage, bedding, and a balanced diet to thrive.
