* Protection: Hamsters are small and vulnerable, and their babies are even more so. Carrying them in their mouths allows them to keep their young close and protected from predators or other dangers.
* Transportation: Hamsters need to move their babies to different locations, such as to a new nest or to a safer spot. Carrying them in their mouths is the most efficient and safest way to do this.
* Warmth: A mother hamster's body temperature is warmer than the surrounding environment, so carrying their babies in their mouths helps keep them warm.
* Stimulation: The movement of being carried in the mother's mouth can help stimulate the babies' development and encourage them to grow strong.
It's important to note that hamster mothers are very protective of their young. If you see a mother hamster carrying her babies, it's best to leave her alone and give her space. Don't try to handle the babies or interfere with her maternal care.
