Dwarf hamsters have slightly different dietary needs than larger hamster species like the Syrian or teddy bear hamster. They have higher metabolisms than larger hamsters and need more protein. But dwarf hamsters are not picky and will eat just about anything they can stuff in their mouths, so it is up to you make sure that the food they are stuffing is as nutritious as possible.
Basic Diet
Pet rodents have teeth that grow continually throughout their lives, so they need access to treats, toys and food that helps wear their teeth down. If the front teeth get too long, the hamster can't eat. Therefore, basic dwarf hamster food should be hard, such as commercial pellets, seeds and washed fresh vegetables like carrots, broccoli and cucumber. Avoid sunflower seeds or pet rodent mixes with sunflower seeds as these are far too high in calories. Also, avoid nuts except as an occasional treat as these are also way too high in calories, although they do help give a quick protein boost to pregnant dwarf hamsters. A mealworm, small bit of cheese or hard boiled egg is also recommended as a weekly treat for dwarf hamsters.
