Small rodents include the lesser Egyptian jerboa, the Cheesman's gerbil and the Balochistan gerbil. However, the location of these motoneurons differs in the rat, Mongolian gerbil and domestic pig. These rodents are the most docile species of the Gerbil subfamily. Smaller mammal species are the Mongolian gerbil, the little souslik and the bobak marmot. The Mongolian gerbil, a gentle and hardy animal, has become a popular small house pet. She also adopts the class pet gerbil, Frisky. Desert inhabitants include the bustard and midday gerbil. The mating ritual of the fat-tailed gerbil is rather unusual. This fat-tailed gerbil is greyer in colour. Therefore, a healthy fat-tailed gerbil should have a nicely rounded tail. The mating ritual of the fat-tailed gerbil may also be confused with fighting. The smallest known mammalian prey was a Cape gerbil ("Gerbilliscus afra"). The fat-tailed gerbil is a medium-sized gerbil. The gestation period of the fat-tailed gerbil is 19 days. The giant gerbil gets revenge by chasing and finally devouring the fairy.
