Here's a breakdown:
* Young rodents: Tend to have a higher water content, often closer to 75%.
* Older rodents: Water content may decrease slightly as they age.
* Species variation: Larger rodents, like rats and hamsters, may have a slightly lower water percentage than smaller ones, like mice.
It's important for rodents to stay hydrated to maintain their health. Dehydration can be a serious problem for them, leading to various health issues.
