If you have a hamster, you are probably always on the lookout for tasty treats that you can offer, but making sure that these are safe is of paramount importance. You don’t want your hamster to get sick because of something you have fed it.

Hamsters can eat bananas in small quantities, and they will get some health benefits from doing so. However, like all treats, they must be fed in moderation, as excessive amounts of bananas could result in your hamster getting sick. A little banana on an infrequent basis should be fine. 

Let’s find out more about how to safely feed your hamster bananas and avoid any issues occurring.

Can My Hammy Have Bananas?

Hamsters can safely eat bananas, and many people offer their hamsters small amounts of this fruit from time to time. They seem to relish the sweet flavor and the soft texture, and you may find that your hamster eagerly grabs a banana from you any time you offer it.

This should be safe as long as you keep your hamster’s diet in check and do not give it too much fruit (of any kind) overall. Remember that hamsters are significantly smaller than humans, and what looks like a small amount to you can be a huge portion for a hamster.

Bananas offer certain benefits, including:

  • Vitamins and minerals
  • Fiber
  • Antioxidants
  • Mental stimulation

Bananas are counted as safe food, but they must be fed in moderation. If your hamster is unwell or overweight, you may wish to remove all treats from its diet until it has recovered.

How Much Banana Can Hamsters Have?

Hamsters can have a small piece of banana a couple of times a week, spaced out over several days.

Do not give your hamster banana in large quantities or for two days running, as its digestive system needs time to deal with the sugars and other components. Spacing the banana treats out ensures that it has time to do this and reduces the risk of stomach upsets.

What counts as a small piece of banana will depend on the size of your hamster. If you have a small hamster, such as a Dwarf, you will need to scale down its treat allowances accordingly. There are no exact estimates on how much a hamster can have, but if the animal can hold the treat comfortably between its paws, it is usually a reasonable size. 

As a rough guide, a Dwarf hamster should be okay with eating up to ¼ of a teaspoon of banana a couple of times per week. A larger hamster might be able to have 1/3 of a teaspoon a couple of times per week. However, you should also think about the other foods that your hamster eats and adjust its banana intake accordingly. If your hamster has a lot of other fruit, cut back on the banana a bit.

Remember that fruit is very sugary, and eating a lot could make your hamster sick. You need to give it banana in smaller quantities if other fruits are being consumed alongside it. Overall, treats should not make up more than 10 percent of your hamster’s diet.

What Makes Banana Healthy For Hamsters?

There are a number of things that make bananas healthy for hamsters, including:

  • They contain antioxidants, which can help to fight off certain kinds of cancer and some diseases.
  • They contain vitamin A, vitamin C, and vitamins B1 and B6. These boost your hamster’s immune system, eyesight, growth, and reproductive system. Vitamin deficiencies can lead to many issues, so these vitamins are beneficial.
  • They contain calcium, which is excellent for your hamster’s bones.
  • They contain magnesium, iron, and potassium, which are vital minerals that serve a variety of purposes in the body.
  • They contain fiber, which helps to keep your hamster’s digestive system moving and lets it process sugars more effectively.

All in all, bananas are a good snack for hamsters if they are fed to them in small quantities, and they also offer mental stimulation and enrichment. 

Like people, hamsters enjoy getting treats, so a little piece of banana is a great way to reward your hamster or brighten up its day.

What Happens If Your Hamster Overeats Banana?

If your hamster eats more banana than it should, it is at risk of various health complications. The most obvious one tends to be diarrhea and an upset stomach, which can be very uncomfortable for a hamster.

It can be challenging to assess how much food your hamster has in its cage, as it may carry it off and bury it. It can lead to over-eating, which causes obesity. Bananas have a lot of sugar in them, which puts your hamster at risk of weight gain. 

Obese hamsters can suffer from health complications, just like humans. Diabetes is a common issue, but a fat hamster may also suffer from joint pain and other health complications.

If your hamster eats too much banana, it may also neglect other foods in its cage, including its main food mix. This food mix has been carefully tailored to ensure your hamster gets everything it needs. If it doesn’t eat enough of this, it is at risk of vitamin deficiencies, and it may start to suffer from other health complications.

Therefore, you should keep an eye on your hamster when you give it a treat. If it takes the treat away and buries it, it may be getting too much food, and you might need to cut back on its treats.

Are Bananas Good For Your Hamster’s Teeth?

Unfortunately, bananas are not great for your hamster’s teeth. Rodent teeth grow continuously, and hamsters depend on hard foods (which make up most of their natural diet) to grind their teeth down and keep them in good shape.

If the teeth are allowed to grow, they can cut into the animal’s mouth and cause injuries.

Bananas will not help keep your hamster’s teeth in good shape, as they are soft and won’t grind any of the teeth away.

If your hamster overeats bananas and other soft foods, you may find its teeth grow longer than they should, which can be painful.

Can Hamsters Have Dried Banana?

Dried banana does not tend to be a safe offering for hamsters because fruit drying often involves adding extra ingredients to help dry and preserve it. If you give your hamster dried banana, it is likely to get sick because these ingredients may not be safe for it to consume.

Banana chips also have a much higher sugar ratio because the water has been removed. They can contain double the amount of sugar found in fresh bananas, making them unsuitable for your hamster.

Can Hamsters Have Banana Peel?

The peel of a banana may not be very appetizing to humans, but it is safe for your hamster.

It is lower in sugar and higher in fiber than the fruit, which may make it preferable in terms of health – but your hamster may not be particularly interested in eating it.

Many hamsters reject banana peel and will discard it or bury it. You should remove it from the cage if your hamster doesn’t eat it within a day.

How Can I Tell If My Hamster Will Like Banana?

The best way to determine whether your hamster is likely to enjoy banana is to offer it a piece.

You should always give a very small portion of food to your hamster the first time it tries something new, in case it causes a reaction. While bananas are generally considered safe, this is an excellent precaution to take.

Cut a small piece of banana off the fruit and offer it to your hamster to see how it responds. Most hamsters will eagerly grab the fruit and devour it. If your hamster stashes it, you should wait to see if it later eats it before giving your hamster any more.

Once your hamster has eaten the banana, wait for a few days before you offer it any more. This will let you observe the hamster and make sure no issues occur with its droppings.

If the banana seems to have caused digestive problems, don’t give your hamster banana in the future. Choose other fruits that do not cause stomach problems.

Don’t worry if your hamster doesn’t seem to like banana. This is not a crucial food for your pet to eat, so you can simply offer other treats and leave bananas off the menu.


So, now you know that hamsters can eat bananas and will enjoy some health benefits from them. However, make sure that banana consumption is moderated, especially if your hamster eats many other treats.

Do not give your hamster bananas if it is overweight, as the sugar will contribute to further weight gain.
