why do they stuff their cheeks?

Question
I want to know why hamsters stuff their cheeks?  

Answer
Hamsters, and all rodents, stuff their cheeks as a way of moving food. Hamster from a German word meaning "to hoard". All rodents enjoy hoarding their food, which means making a large, hidden stockpile of food. Most do it to ensure even when no food is to be found, they still have enough in their hoard not to starve. A hamster in captivity stuffs it's cheeks to transport the food from the bowl to it's hoard, usually the sleeping place.
