So you've brought home a furry little hamster and you want to make sure you're providing the best possible care for it both in its grooming and nutrition. 

When it comes to your pet's nutrition, you may have heard that they can eat nuts, but are unsure if they are all safe to give to your hamster?

What Are Nuts?

Nuts are small, hard seeds that grow on trees and vines. There are many different types of nuts, from almonds to walnuts, and each one has its own unique flavor and texture.

Hamsters love to eat nuts, but it's important to know which ones are safe for them to eat. Some nuts, like macadamia nuts, can be poisonous to hamsters. So it's important to do your research before giving your hamster a nutty snack.

Are Nuts Safe for Hamsters To Eat?

That's a great question! The short answer is yes, hamsters can safely eat nuts, but there are a few things to keep in mind.

First of all, different kinds of nuts can have different effects on hamsters. For example, walnuts are high in omega-3 fatty acids, which are good for hamsters, but cashews are high in sodium, which isn't good for them.

Secondly, you should always keep it moderate when feeding your hamster nuts. A little bit of nuts is okay, but too many can make your hamster overweight or give them an upset stomach.

So to sum it up, yes, hamsters can safely eat nuts, but make sure to keep an eye on what kind and how much they're eating.


What Types of Nuts Can Hamsters Eat?

Hamsters can eat most types of nuts, but there are a few that you'll need to avoid. 

Some of the most popular nuts that hamsters can eat include almonds, Brazils, chestnuts, hazelnuts, pecans and walnuts. 

The most important thing is to make sure that the nuts are unsalted and raw. Remember to also avoid giving your hamster any type of nut that is coated in chocolate or sugar, as these can be harmful.

What Nuts Are Unsafe For Hamsters?

There are some nuts that you should avoid feeding your hamster entirely. These include, but are not limited to:

  • Walnuts: the shell of a walnut is far too hard for your hamster to chew and can cause serious damage to their teeth. Additionally, the high fat content of walnuts can lead to obesity.
  • Macadamia nuts: these contain a toxin that can cause neurological problems in hamsters.
  • Cashews: like walnuts, cashews have a very hard shell that can damage your hamster's teeth. Additionally, they contain a compound that can prevent your hamster from absorbing calcium, which is essential for bone health.

So, what should you do if your hamster does manage to get their hands on one of these nuts? The best course of action is to contact your veterinarian immediately.

What Nutritional Benefits Do Nuts Give to Hamsters?

Nuts, in general, are a great source of protein, healthy fats, vitamins and minerals for hamsters. The nutritional benefits of different nuts vary, but all nuts are a good source of energy for hamsters. 

For example, almonds are a good source of magnesium, which is important for bone health. They are also a good source of protein and fat; and contain calcium, phosphorus, and vitamin E. 

Almonds are a good source of fiber, which is important for your hamster's digestive health and pistachios are a good source of potassium, which is important for heart health.

Hamsters also like the taste of nuts! They are a tasty treat that your hamster will enjoy. Just be sure to give them in moderation, as they are high in fat.


Are There Any Risks Associated With Feeding Hamsters Nuts?

Just like with anything else, there are always going to be some risks associated with feeding your hamster nuts. 

  • The biggest one is that nuts are a choking hazard. So, if you do decide to feed your hamster nuts, you'll want to make sure that you're doing so responsibly and monitoring them closely.
  • Another risk is that some nuts contain high levels of fat and sugar, which can lead to obesity and other health problems in hamsters. 
  • Of course, there's always the potential for an allergic reaction. If you notice your hamster starting to scratch more than usual or exhibiting any other unusual behaviors, it's best to err on the side of caution and stop feeding them nuts right away.

As long as you are aware of the risks and take precautions accordingly, there's no reason why you can't safely include nuts as part of your hamster's diet.

Tips for Feeding Your Hamster Nuts

Here are a few things to keep in mind if you're planning on giving your hamster nuts as part of their diet:

  • Make sure the nuts you are giving them are unsalted and unroasted. Roasting nuts can make them more difficult for your hamster to digest, and salt is obviously not good for them.
  • Give them only a small amount of nuts at first to see how they react. Some hamsters might have trouble digesting nuts, so it's best to start with a small amount and then increase gradually if they seem to be doing okay.
  • Choose smaller nuts like almond slivers or hazelnut pieces so they're not too much for your hamster to handle.
  • Avoid giving your hamster nuts with shells, as these can be a choking hazard.


Most hamsters love nuts, but you have to be careful about the kind you give them. For example, salted nuts are a big no-no, as the salt can cause dehydration and other health problems.

If you feel that feeding your hamster nuts may pose a huge risk to their health, the best thing to do is to speak with your vet to get their professional opinion on the matter. They will be able to tell you specifically which nuts are safe for your hamster to eat, and which ones are not.
