hampster feeding

Question
What does mean when a hampster stuffs a buch of food in it's mouth al at once and it's jaws get really big?

Answer
hamsters have little pouches in their cheeks where they store food. it's a natural thing and it just means that the hamster is making sure it has enough food in case rough times may happen. In the wild hamsters live where there is not a lot of food so they store food in case they can't find food for a few days.
