However, the number can vary depending on factors like:
* Age of the mother: Younger gerbils might have smaller litters.
* Health of the mother: A healthy mother can have larger litters.
* Genetics: Some gerbils are predisposed to having larger or smaller litters.
It's important to note that gerbils can have multiple litters per year, so if you have a breeding pair, you can expect a significant increase in the number of gerbils in your care.
