In nature there are about 14-15 kinds of gerbils. They are very docile and rarely bite, they tend to get away and jump. 
Distribution: steppes of Mongolia and China, suitable for arid, cold and inhospitable climates.
Feeding: pellet feed for mice and hamsters, containing about 18-22% protein. Unsweetened whole grains may also be used. Gerbils are very greedy of seeds (especially sunflower), but do not exceed: they are in fact fat seeds. The feeding can be integrated with some fresh vegetables, and fruits.
