swollen cheeks

Question
I have a teddy bear hamster. It was fine, and all of a sudden, I just noticed that it has like swollen cheeks. it is on both sides. There is hard like stuff under the skin. She is fine, eating, an on the excersise wheel all the time. But it is creepy. It is like her body is a figure 8. It is really my 4 year olds, and she is very worried. Please help.  

Answer
Hello, it seems like she is just stuffing her cheek pouches. It's a normal hamster thing. Hamsters have cheek pouches where they are able to store extra food and they just pop it out and eat it. It's very common and funny to see because it looks like their mouth is swolen. :-) They developed the cheek pouches since where they originally come from they may not find food some days and so to not go hungry they collect all the food they can in their den and in their mouth.
