No Comments

Blackberries are a tasty summer fruit that many people enjoy eating fresh or using in recipes. As small pets, hamsters have different dietary needs and restrictions than humans.

So a common question hamster owners have is whether blackberries are safe and healthy for hamsters to eat. In this blog post, we’ll take an in-depth look at blackberries for hamsters.

What Are Blackberries and Where Do They Come From?

Blackberries belong to the Rubus genus in the Rosaceae family and are an aggregate fruit composed of many drupelets around a central core. They have a deep purple-black color when ripe and a sweet, tart flavor enjoyed by humans and animals alike.

Blackberries grow wild across North America, Central America and South America on brambles and canes in meadows, open forests, and woodland areas.

They’ve been harvested and eaten by Native American tribes for centuries and also grown cultivated on farms for commercial sale.

Blackberry Plant Description:

The blackberry plant is a deciduous, perennial shrub with thorny stems known as canes. The canes grow erect, arching, or trailing along the ground up to 10 feet long.

Tiny white flowers bloom on the canes in spring, developing into the familiar oblong blackberry fruit by mid-summer.

Once the berries ripen, the cane dies back, and new first-year vegetative canes emerge from the plant’s crown below ground to repeat the two-year growing cycle.

Uses for Blackberries:

Blackberries have long been used and enjoyed both fresh and cooked in various foods. Their sweet/tart taste lends well to jams, desserts, juices, wine, cereals, trail mixes and as a topping for yogurt, ice cream or oatmeal.

Packed with vitamin C, antioxidants and fiber, blackberries are nutritious and often described as a “superfood” in human diets. With growing awareness of their health benefits, blackberries are increasing in popularity.

Can Hamsters Eat Blackberries?

Yes! Hamsters can safely eat blackberries in moderation as an occasional treat. Their small size means hamsters should only eat a few tiny pieces at a time.

But their sweet taste and nutritional value make blackberries a healthy supplement to a balanced hamster diet.

Can Dwarf Hamsters Eat Blackberries?

Both dwarf and Syrian hamsters can enjoy fresh blackberries. But dwarf varieties like Campbell’s Russian dwarf hamsters should eat fewer due to their tiny size. Only feed them tiny portions of soft, ripe blackberry flesh occasionally.

Can Hamsters Eat Human Blackberries:

Wild blackberries and store-bought blackberries from the grocery store are fine for hamsters as long as they are washed thoroughly. Unsweetened and untreated fresh blackberries are the healthiest choice.

Avoid offering hamsters processed foods like blackberry jams, juices or baked goods.

Can Hamsters Eat Blueberries and Blackberries:

Hamsters can eat a small sampling of blueberries and blackberries to mix things up! These fruits offer similar health benefits and are non-toxic, seedless fruits hamsters can digest easily. Rotate them each week or stick to one at a time in tiny amounts.

Can Hamsters Eat Raspberries and Blackberries:

Raspberries offer comparable nutrition and fruit sugars as blackberries that hamsters can also tolerate well in moderation.

Combine them in the same feeding or rotate between the two from week to week for variety. Just don’t overdo it!

Can Syrian Hamsters Eat Blackberries:

The larger size of Syrian or golden hamsters means they can handle slightly more blackberry treats than dwarf types. But they should still only consume tiny bite-size pieces on occasion. Not in excess or daily.

Are Blackberries Healthy for Hamsters?

Loaded with beneficial vitamins and antioxidants hamsters need, blackberries can be a nutritious supplement for hamsters.

Containing natural sugars and fiber, they can satisfy a hamster’s sweet tooth too. Some of the main nutrients found in fresh blackberries include:

Blackberry Nutritional Facts;

1 Cup of Raw Blackberries Contains:

  • Calories: 62
  • Total Fat: 0.7 g
  • Total Carbs: 15 g
  • Dietary Fiber: 8 g
  • Sugars: 7 g
  • Protein: 2 g

Vitamin C:

With 30 mg or 33% RDI per cup, vitamin C is abundant in blackberries. It acts as an antioxidant and helps hamsters absorb iron while supporting a healthy immune system.

Fiber-rich Food:

The small seeds provide 8 grams of dietary fiber per cup, promoting healthy digestion in hamsters. Fiber also helps stabilize blood sugar levels.


Blackberry skin and juice contain anthocyanin antioxidants to reduce inflammation and lower disease risk by neutralizing harmful free radicals.

Vitamin K:

Important for blood coagulation, hormone balance and bone health, blackberries contain 29 mcg of vitamin K.

Vitamin A:

Aiding vision, bone growth and immune function, blackberries contain 214 IU of Vitamin A per cup.

Nutritional Risks of Overfeeding Blackberries:

Despite the benefits, too many blackberries could cause problems for hamsters. Their small digestive systems are only designed to handle a little fruit sugar at a time.

Introduce blackberries slowly and limit treats to avoid issues like:


Excessive fruit sugar from too many blackberries may lead to loose, watery stools if a hamster’s sensitive digestion is overwhelmed.

Weight Gain:

The natural sugar calories add up fast. Overindulging could cause obesity over time.

Sticky Food Residue:

Blackberry juice drying on hamster fur is messy and attracts dirt in bedding. It can be hazardous if ingested through grooming as well.

Choking Hazard:

The tiny seeds and skin could present a choking risk if eating too much at once. Always dice blackberries into chewable pieces first.

Can All Breeds of Hamsters Eat Blackberries?

Most hamsters can eat blackberries, but smaller breeds should only have a tiny portion. Suitable breeds include:

Syrian Hamsters:

As the largest breed, Syrian hamsters can handle slightly bigger portions of diced blackberry in moderation.

Dwarf Campbell Russian Hamsters:

The Roborovski Dwarf and common Russian Campbell Dwarf hamsters can have part of a blackberry but need much smaller pieces.

Larger Breeds Like Chinese Hamsters:

Big breeds such as Chinese teddy bear hamsters can also eat tiny blackberry pieces relative to their size every few days. Monitor intake with any species.

How Many Blackberries Are Safe and How Should They Be Prepared?

To safely integrate blackberries into a hamster’s existing balanced diet, follow these tips:

Offer Only Occasionally:

Blackberries should only supplement a hamster’s main commercial food, not become a daily staple. Once or twice a week is often enough.

Wash Thoroughly:

Always rinse store-bought blackberries to remove pesticides. Pat dry before serving.

Dice Into Tiny Pieces:

Chop large blackberries into manageable, bite-size pieces your hamster can chew well before swallowing. Remove any stems or leaves first.

Only Feed 1-2 Pieces Per Serving:

Limit treats to just a piece or two at one time, even for large Syrian hamsters. Tiny dwarf breeds need half a piece of blackberry or less.

Avoid Hamster Cheek Pouch Storage:

To prevent excess treat hoarding, offer berries directly in a dish instead of through cage bars where they could stash extras in cheek pouches.


Can hamsters eat blackberries everyday?

No. Blackberries should only be an occasional treat 2-3 times per week at most. Too much fruit will upset their digestion.

What happens if a hamster eats too many blackberries?

Gastrointestinal upset can occur, causing loose stool, diarrhea, and tummy pain. Overfeeding blackberries long-term may also lead to obesity and related illnesses.

Do blackberries make good hamster treats?

Yes! ,

 Blackberries make a nutritious, fiber-rich, natural treat hamsters tend to love. The sweet taste and fun texture gives bored pets something different to look forward to.


Blackberries can be a safe, healthy supplement for hamsters when fed properly in strict moderation. Their nutritional profile brings valuable antioxidants, vitamins and fiber hamsters can benefit from.

Yet their tiny digestive systems call for extreme care not to overdo high fruit sugars. With judicious portion control, hamsters can enjoy blackberries as an exciting treat. Check with your exotic vet if ever unsure about appropriate hamster nutrition and treats.
