Can Hamsters Eat Grapes? Stay Away From These 6 Fruits For Your Hamster’s Health

You may be mixing a yummy fruity snack for your little furry friend and questioning if it is safe to include grapes in the recipe. If you have several pets, such as canines or cats, you might already be aware that grapes are harmful to them. So, is it the same for your hamster? Can hamsters eat grapes?

If you want to find out the answer, keep on reading! We’ll also include the top 6 fruits to stay away from for the sake of your hamsters! 

Can Hamsters Eat Grapes? 

Yes, they can. Grapes aren’t dangerous to hamsters; however, you should take caution regarding the preparation step and the serving frequency.

Is it Safe And Beneficial For Your Hamster To Feed On Grapes?

Absolutely! Grapes are a rich source of antioxidants, vitamins, and nutrients. They contain a lot of vitamin K and C and minerals like phosphorus, calcium, potassium, and magnesium.

Your hamster’s system requires vitamin K to deal with blood coagulation. Vitamin C is necessary for a healthy and robust defensive barrier. Phosphorus and calcium aid in developing and maintaining a robust skeletal structure in the hamsters.

Moreover, grapes could help hamsters with vitamin C deficits by increasing their food consumption of this vitamin.

But that’s not everything. Grapes also entail fiber, which could aid in the proper functioning of your hamster’s gastrointestinal tract. These fruits are also high in moisture, preventing the hamsters from dehydration in hot conditions.

What If I Overfeed My Hamster With Grapes?

Hamsters enjoy the delicious sweet flavor of grapes. However, these fruits might cast adverse impacts if taken in excess, considering sugar isn’t an essential element of a hamster’s eating plan and might cause health problems.

Indeed, consuming grapes excessively could lead to health problems such as diabetes and fat buildup in their livers. In addition, having an excessive number of grapes could also lead your hamster to amass an unhealthy load of weight.

If your little buddy is a Chinese Dwarf Hamster, it’s better not to give him grapes whatsoever. The high sugar level of grapes may increase the risk of diabetes in this species, a condition that they are already predisposed to.

Campbell’s hamsters are also more likely to acquire diabetes; therefore, although the danger isn’t as significant as it is for Chinese Dwarfs, you may still want to eliminate grapes out of the menu for this hamster.

If you’re unsure what kind of hamster you get, it’s better to check with your vet before feeding them grapes. Syrian and Roborovski hamsters are less likely to acquire diabetes; thus, you might loosen up the rules a bit for them.

Furthermore, too many grapes in one meal may cause gastrointestinal problems in your furball, such as stomach discomfort and diarrhea. Also, even though grapes are not poisonous to hamsters, they may cause an allergic response in some hamsters. Thus, consult your vet beforehand.

Can Hamsters Eat Grapes With Seeds In and Skin On?

Grape seeds are big enough to pose a choking risk for your little pet. Therefore, although you could still give them grapes without de-seeding, keep in mind to always get rid of their seeds.

Since this could be challenging and time-wasting, using seedless grapes is the better solution.

If the hamster accidentally eats a grape with seeds, you should call your veterinarian for reassurance. Although the seeds are not harmful, they might obstruct your hamster’s digestive system.

The skin of a grape is not harmful to hamsters. However, you might want to peel it to minimize the chance of insecticide exposure to your hamster. 

How To Add Grapes To Your Hamster’s Menu

If you want to begin introducing grapes to your furry friend’s menu, begin feeding a tiny bit amount, exactly like what you would do with any new food. We suggest trying with ⅛ of a grape and gradually raising the amount to 1⁄4 of a grape once or twice per week.

Keep track of your hamster’s behaviors to ensure they aren’t having any adverse response or a digestive issue. Symptoms to keep an eye out for include:

  • Low-spirited: This occurs when hamsters consume non-nutritional things such as their blanket or a piece of newspaper. It is a self-soothing action; therefore, it might indicate that anything they ate, such as your piece of grape, is giving them discomfort.
  • Digestive problems: If your furball gets watery poop or diarrhea, stop feeding them grapes. Diarrhea might cause exhaustion if not treated right away.
  • Energy-lacking: If your hamster appears to be lacking enthusiasm after having new food, he might be having difficulty digesting it.
  • Lack of appetite: One more clue that the new feeding, such as grapes, hasn’t gone down well with your hamster’s stomach. In this case, they’ll start losing interest in eating their regular diet.

If any of those signs persist for more than 2 days, contact your veterinarian and schedule a visit to check your furry friend.

Note: Hamsters under 4 weeks old shouldn’t eat grapes in any circumstances.

Is It Good To Add Grapes Into Your Hamster’s Everyday Meal?

Most of your hamster’s nutritions always come from their kibble and everyday veggie serving. Of course, you could offer fruits, especially grapes, as a treat, but they should not be a daily ingredient of your hamster’s menu.

If your hamster is currently eating a good kibble, grapes will not offer many health advantages. 

Can Hamsters Eat Raisins? 

Yes, raisins are completely safe for your hamsters to consume. 

Raisins provide several nutritional perks for your little pet. This food is not only packed with vitamins A and B, which support a stronger immune function and cellular development, but they can also benefit your hamster’s kidney and gastrointestinal organs and safeguard him against some malignancies.

Given the different health benefits of raisins, there exist a few potential drawbacks involved in giving raisins to your hamster. First and foremost, raisins contain lots of sugar. If given in excess, your hamster could get obesity and diabetes.

Furthermore, eating raisins excessively might harm your pet’s kidneys. That’s why it is vital to limit his raisin consumption.

Top 6 Fruits You Should Avoid Feeding Your Hamster

Now you know grapes aren’t bad for your hamster; it’s time to find out what’s not to give to your furry friend. Below are 6 fruits you should never let your hamster try!

Bitter Almonds

If your hamster gets his hands on some bitter almonds, the consequences might be fatal. This is because the almonds themselves possess emulsin, an enzyme responsible for producing aromatic oils, cyanide, and glucose.

What’s even deadlier about bitter almonds is that they contain 42 times the cyanide of sweet almonds. And this cyanide is a highly poisonous substance, meaning if your hamster consumes a large dose of cyanide, he will die.


Another veggie (well, actually a fruit) that might harm your hamster is your everyday tomato.

Tomatoes are highly acidic, despite being sweeter than other foods. So if your hamster ate too many of them, he or she would have diarrhea.

You must also refrain from offering your hamster tomato greens at any time. They are poisonous and can be fatal if consumed even a tiny bit. For this reason, you should remove this fruit/veggie from your hamster’s meals.

Oranges And Citrus Fruits

Can hamsters eat oranges? Yes, they can, and actually feeding them only a tiny bit of citrus fruits won’t probably cause any harm.

However, as mentioned above, fruits with high acidity (which means all citrus fruits) are not suitable for your little furball. These foods contain a large amount of acid, which might be detrimental to your hamster’s digestive system. Even in nature, hamsters eliminate such fruits since the scent of citrus is repulsive.

Star Fruits

Star fruit is not suitable for hamsters as it contains a lethal neurotoxin to hamsters and many other pets. It could also induce renal difficulties in certain animals, including hamsters. Thus, it’s advisable to keep your hamster away from it.

Dragon Fruits And Seedy Fruits  

While dragon fruits have some helpful elements for hamsters, it is preferable not to offer this fruit to your little companion. This is due to the increased possibility of the seeds suffocating your hamsters.

Similar to that, you should also steer clear of any seedy fruit like kiwi or blackberries. 

Top 4 Best Fruits You Can Feed Your Hamsters


Bananas are an excellent snack for your tiny pal. According to the National Research Council, hamsters need to consume approximately 62% carbs to be healthy and fit. However, as you may know, bananas are almost entirely composed of carbs.

Meanwhile, the fiber in bananas is also beneficial to hamsters since it aids with metabolism. 

And the perks do not stop there.

If you have done some research, you’ll know a lack of vitamin B6 might also be a great concern for hamsters. Since hamsters cannot produce vitamin B6, they must obtain it from their diet.

If they do not consume enough of it, they will stop growing until their energy runs out, which will take around 2 – 3 weeks. And if the deficit persists, they will die in 13 weeks.

Hamsters basically could not operate without adequate vitamin B6 levels. Luckily, bananas are a rich source of vitamin B6. Thus, it’s a must-have on so many hamsters’ diet.


We’ve never seen a hamster that didn’t enjoy eating pears! Indeed, most hamsters would like to have a bite of pear every once in a while.

Pears are an occasional snack that hamsters should have in moderation. You could add a small portion of pears into their diet once a week or twice if the pears aren’t too sweet.

This is when things become a little complicated. The more ripe and juicy the pear, the less you would like to feed it to your little one.

Pears that are only slightly ripe and yet a bit crunchy are ideal for feeding your hamsters. Pears in this state are perfect for pets’ snacks (in tiny quantities!); even dwarf hamsters can eat them! This is because ripe ones are full of sugar and can induce diabetes and obesity in hamsters.

Furthermore, do not feed your hamster pears on the same day as similar sweet foods unless you chop each of the fruits into tiny amounts and serve no more than a tsp at a time. Finally, if you get a dwarf hamster (which is particularly susceptible to diabetes), try to restrict sweets even more.


Apples are the perfect treat for your hamsters. 

The primary benefit of apples is that they are high in vitamin C (yet not too acidic), crucial for hamsters since it promotes optimal recovery and reduces scurvy’s risk.

Vitamin C also aids in the optimization of the hamster’s immune mechanism and the maintenance of healthful fur. Like other fruits and veggies, apples are high in antioxidants, which can assist your hamster in battling sickness and cancer.

Apples also include fibers necessary for a hamster’s gastrointestinal tract. Apples are a low-calorie food that will not accumulate fat or diabetes in hamsters.

Although apples are an excellent treat for hamsters, pet parents should be mindful of a few issues. To begin with, hamsters may suffocate on apple seeds; therefore, you should never give them apples with seed still there. Before feeding your hamster, carefully look for and discard any seeds.

Additionally, while apple skin is safe for hamsters, large portions might be difficult for them to rip apart using their mouth, increasing the risk of choking. As a result, even ¼ of an apple with the skin on it might cause issues.

Thus, make sure only to give your pet peeled and de-seeded apples. 


Blueberries are low in calories and sweetness, making them an excellent supplement to any regimen. In addition, they’re highly nutritious, with many nutrients such as fibers, antioxidants, proteins, and vitamins K, C, B6, and E.

Blueberries are just as beneficial for hamsters as they are for us. If consumed in moderation, they could assist in regulating your hamster’s bowel motions and even enable him to fend against oxidation, which can increase the risk of cancer.

Furthermore, blueberries could support your little friend to shed some pounds, strengthen his immunity, and lessen his chance of high cholesterol.

Yet, keep in mind that any kind of food, especially blueberries, should never account for more than 20% of your hamster’s entire everyday intake. For one hamster, this equals about 1 tsp of blueberries each day. The quantity is significantly lower for dwarf hamsters.

Although blueberries contain less sugar and lower calories than other fruits, they may rapidly add weight to your hamster if they eat this fruit a lot. In the end, hamsters are susceptible to obesity and will almost certainly gobble every delectable food.

Wrapping Up 

Hamsters can eat grapes and a lot more fruits. However, not all the fruits are safe for them; thus, be mindful and ask your doctor before feeding them. Also, only consider fruits as an occasional snack, as these fruits might lead to extra pounds in your already-susceptible-to-obesity furry friend. Off we go!
