Mass of gerbil (grams) v. Age in weeks

It is difficult to provide an exact mass of a gerbil in grams per age in weeks as the weight of a gerbil can vary based on factors such as genetics, diet, and overall health. However, as a general guideline, a young gerbil may weigh around 10-15 grams when it is 4 weeks old. As the gerbil matures, its weight will gradually increase, with adults typically weighing between 50-100 grams.

It is important to note that these are just rough estimates and individual gerbils may vary in weight. Regularly monitoring the weight of your gerbil and consulting with a veterinarian if you have concerns about its growth or health is recommended.
