How to Feed Walnuts (and other nuts) to hamsters.

If you want to give your hamsters nuts, make sure they’re not salted or seasoned.

If so just give them a wash and she should be fine! It’s also important that we remove any shells before feeding the nut butter as well because sometimes hamsters can have issues with their digestive system when eating things like this (although very rare).

To begin, cracking open the walnut shell on your own is preferable to leaving it to the hamsters, who may or may not be able to do it.
Only give your gigantic hamster one walnut a week as a treat.

Conclusion: can hamsters eat walnuts?

Walnut is a safe nut for hamsters to eat, but they may not like the taste. Hamsters can eat raw walnuts as well as whole walnuts, but they will not like to eat the outer shell of the nut.

If your hamster does not seem to be interested in eating walnuts, you can try mixing them into their food or giving them a small piece of fruit or vegetable along with the nut.
