Walnuts

Walnuts are nutrition-packed snacks. They contain large amounts of calcium, magnesium, phosphorus, protein, and a ton of vitamins, including vitamins A, B1, C, E, and K.

Walnuts can also help hamsters to develop and maintain tissue, build strong bones, prevent diabetes, and destroy harmful free radicals inside their bodies.

You should only feed your hamster walnuts in moderation, not as a daily component of their diet.
