Can hamsters eat peanuts?

Quick verdict

Why

A plain, unsalted peanut now and then is fine for hamsters.

Can hamsters eat peanuts, and why?

A plain, unsalted peanut now and then is fine for hamsters. High in fat, so keep portions tiny and never give salted nuts.

Hamsters are omnivores who do best on a complete hamster mix, with small amounts of fresh food as treats. They are tiny and prone to obesity and diabetes (especially dwarf hamsters), with sensitive tummies, so portions must be minimal and sugary or watery foods limited.

How to feed peanuts to hamsters

  • How much: One plain, unsalted peanut occasionally.
  • How often: An occasional treat, not a daily food. A treat should be no bigger than a piece they can hold in their paws — roughly a teaspoon or less, once or twice a week.
  • Young pets: Young hamsters should stick to their staple mix; introduce treats only once they are well established, in tiny amounts.
  • Preparation: Always wash fresh produce, remove any pips, stones, seeds, peel or tough skin where relevant, and serve it plain — never with salt, sugar, oil, butter or seasoning.
