The wheel will become unmoveable if you place it on the floor of the cage because the gerbils will bury part of it or tip it over. If you hang the wheel from the screen lid, it will always run freely. There is a slight danger that your gerbils may get caught in the wheel, but this is uncommon. Breeding Gerbils will become sexually mature at the age of two months. They will have litters of one to eight pups, the average being two to four.
Gerbils stop producing young around the age of two and a half years.
The gestation period is approximately twenty-four days, or three to four weeks. Baby gerbils are born without fur, and they are blind and deaf. Their skin turns dark in about three days, and by six days they are covered in light fur. By the twelfth day, their eyes are open. Lifespan Gerbils will live from three to five years if you follow the guidelines listed above.
