We love our hamsters, and our hamsters love us! Love extends to many things but it especially includes ensuring that our hamsters are eating food and treats that are healthy and nutritious for them! We wouldn’t be very good parents if we were feeding them things that hurt their health. This often means that we wonder what kind of treats hamsters can eat, for instance, can hamsters eat walnuts? The good news is that, yes, hamsters can absolutely eat walnuts! They can be a delicious snack for your pet, as long as they are fed in moderation.

This article will be looking at the benefits and risks of feeding your hamster walnuts, as well as letting you know the recommended quantity that you should feed them. We’ll also look at how to feed walnuts to your pet! and what parts of the walnut are good for your hamster!

What are Walnuts?

Walnuts are a delicious nut that grows in a tree, unlike peanuts which grow underground. 3.8 million tonnes are produced each year, mostly by China. This amazing food can be used for garnishes, eaten whole, and can even be used in some medicine! They can be sold with or without the shell and you could even grow them yourself! No wonder so many people are asking if our lovely furry friends can eat them!

Can Hamsters Eat Walnuts?

As stated before, they absolutely can! Our furry friends will find this nut absolutely delicious and will want as many as you can give them! However you have to be careful about the quantities, this is something we will be getting onto shortly. Walnuts have plenty of benefits for your hamster, but also plenty of risks if you feed them too many. However, you should make sure that the walnuts that you give your hamster don’t have:

  • Sweeteners
  • Added salt
  • Extra ingredients, such as honey

They need to be completely natural!

How to feed walnuts to your hamster

When you are giving treats, such as this nut, to your hamster, always make sure you are holding them or make sure that you are close to them. This is because giving treats to your hamster can strengthen your bond and assist in socializing them. Only give a small amount to your hamster at first, this is to figure out if they like walnuts. There’s no point giving your hamster a lot of it if they just ignore it! Your hamster might put the food in their cheek poaches though.

Make sure that you wash the nut beforehand. This gets rid of any of the chemicals that may have been on the nut to protect it whilst it was growing. Pesticides can hurt your hamster’s health. 

Consider feeding walnuts to your hamster as part of a daily diet including treats like pumpkin seedscabbage and carrots! Lots of fruit and vegetables are great for your ham!

How many walnuts can you give your hamster?

The amount of walnuts that you can give your hamster really does depend on your hamster’s breed! Syrians and Robos can have a small amount whilst Dwarfs should only have a very tiny amount! This corresponds to the strength of your pet’s digestive system! Following these guidelines are very important, as we will see later on in this article.

How many walnuts can you give your Syrian Hamster?

Syrian hamsters are the largest domesticated hamster which means that they can have the most walnuts! Give your Syrian a walnut or two every week. This is enough so that they can enjoy the benefits but not too much so that they face the risks of overconsumption!

How many walnuts can you give your Robo Hamster?

Robo hamsters are smaller than Syrians, this means that they can’t have as many walnuts as them. You should give your Robo hamster a walnut every week. This is to prevent overfeeding which can result in many health issues!

How many walnuts can you give your Dwarf Hamster

Winter White dwarf hamsters, Chinese hamsters and Campbell Dwarf Hamsters should eat 1 walnut every 2 weeks. The reason for this drastically reduced amount is that the size of dwarf hamsters is much smaller! This means that a large amount of walnuts will quickly fill them up and lead to problems.

Benefits of Walnuts

Walnuts provide plenty of benefits for humans, but is this the same for hamsters? Absolutely! As long as you feed walnuts moderately to your pet, they will get all kinds of benefits! Some of the benefits of walnuts include:

  • Antioxidants – These protect your hamster against all kinds of age related problems, such as cancer!
  • Protein – This helps your hamster grow big and strong and protects their health
  • Vitamin B – This gives your pet lots of energy and supports their immune system!
  • Vitamin E – This gives your pet excellent eye and skin health!
  • Omega 3 fat – This has been known to improve people’s health!

Risks of Walnuts

Although there are many benefits of walnuts, overfeeding can still cause serious issues. There’s always too much of a good thing and this is especially correct for our furry friends. The digestive system of hamsters is weaker than ours and this can be an issue. Some of the risks associated with overfeeding your pet include:

  • Obesity. – Walnuts are high in fat which means that your hamster could become obese if they eat too much.
  • Digestive issues – Walnuts have a lot of acid which means that too many could cause your hamster to have stomach upsets.
  • Choking – Walnuts can be quite big and this can cause choking. If your hamster is small then consider cutting the walnut in half.
  • Malnutrition – Walnuts can be very filling and this means your pet may not have enough room for their hamster food.

As you can see, these only become a problem with overfeeding! A small amount should be fine for your pet.

What kind of walnuts can hamsters eat?

Here we will be looking at the variations of the inquires related to hamsters and walnuts. Namely walnut shells, roasted walnuts, and black walnuts!

Can Hamsters eat Walnut Shells?

They absolutely can, but they probably won’t want to! Hamsters will attack the shells with their teeth, which is good for them, but won’t eat the actual shell. They are after the delicious nut that is inside! There are no risks if your pet does consume the shell though. Therefore, hamsters can absolutely eat walnut shells!

Can Hamsters eat Black Walnuts?

We honestly don’t know, so we don’t recommend it. There has been hardly any anecdotal evidence or any studies that look into this. Therefore we recommend that you act cautiously and don’t give any to your hamster.

Can Hamsters eat Roasted Walnuts?

Hamsters can eat raw and roasted walnuts, but you need to make sure that they don’t have any additives! Walnuts with honey and other sweeteners may be lovely for humans but they shouldn’t be fed to hamsters. If you want to roast the walnuts before you give them to your hamster, roast them as you normally would but leave them to cool before giving them to your hamster.

Can Hamsters eat Salted Walnuts?

As stated before, the answer is no. Salt can hurt your hamster’s health and the added salt in walnuts is safe for humans, not hamsters! Stick to unsalted walnuts and your hamster will appreciate it!

We have seen the quantities that you should be feeding your hamster and what the best way is of feeding them to your pet.
