Both the Syrian hamster as the dwarf hamster are real hamsters, as their name indicated. They try to eat all, collect it and bring it back in their pouches. These pouches are thin and elastic.
They start at the mouth and run all the way to the shoulders. They are usually used to transport food to the nest. But when danger occurs, they can also be inflated to make the animal look larger.

Sweet or sticky foodstuffs, such as cake or candy, can make the pouches stick together or become blocked. These kinds of food should not be laying around and should not be fed.
As the skin of the pouches is so thin, attention should be paid to sharp edges in the feed, for example with seeds or the membranes of oat flakes.
