Different dwarf hamster species have different dietary needs. In general, Hamster mixes are the perfect food for dwarf hamsters, though an occasional fresh food is good too. However, feeding them fresh food all the time is not a good idea as it may be toxic to them.
Owners should avoid feeding hamsters such foods as potato chips, chocolate and candy, as it can kill these hamsters. Safe food options include barley, cashews, flax seed, millet, oats, pumpkin seeds, walnut, celery, corn, cucumber, spinach, watercress, tofu and yogurt. Safe fruit choices include pear, starfruit, grape, papaya, plum, strawberry, blueberry and blackberry.
