However, it's important to note that:
* This is just an average. Some litters can be smaller (only 1 or 2 pups) or larger (up to 10 pups).
* The size of the litter can vary depending on factors like:
* The age of the mother gerbil: Younger mothers tend to have smaller litters.
* The health and nutrition of the mother: Well-nourished mothers tend to have larger litters.
* The breeding conditions: Stress or overcrowding can impact litter size.
It's always good to consult with a veterinarian or experienced gerbil breeder if you have specific questions about litter size.
