11 Min Read

Cats are known for their love of food and their curious nature, which can sometimes lead them to try out new things. Blackberries are a fruit that many humans enjoy and might want to share with their feline friends, but the question is: can cats eat blackberries? In this article, we will explore the nutritional value of blackberries, the potential benefits and risks of feeding them to cats, and some tips on how to introduce this fruit to your cat’s diet.

Nutritional Value of Blackberries

Blackberries are a delicious and nutritious fruit that can be enjoyed in a variety of ways, from fresh to frozen, or in baked goods, smoothies, and jams. They are rich in vitamins and minerals, such as vitamin C, vitamin K, folate, potassium, and magnesium, and are also high in fiber and antioxidants.

One cup (144g) of blackberries contains approximately:

  • 62 calories
  • 2 grams of protein
  • 0.7 grams of fat
  • 14 grams of carbohydrates
  • 7.6 grams of fiber
  • 7.0 grams of sugar
  • 30.2 mg of vitamin C (50% of daily value)
  • 36.6 mcg of vitamin K (46% of daily value)
  • 28.5 mcg of folate (7% of daily value)
  • 233 mg of potassium (7% of daily value)
  • 29.7 mg of magnesium (7% of daily value)

These nutrients play various roles in maintaining the health of humans and animals, such as promoting immunity, digestion, bone health, and cardiovascular health, as well as reducing inflammation and oxidative stress.

Can Cats Eat Blackberries?

The short answer is yes, cats can eat blackberries, but in moderation and as part of a balanced diet. Blackberries are not toxic to cats, and they can benefit from some of the nutrients found in this fruit, such as fiber and vitamin C.

However, it’s important to note that cats are obligate carnivores, which means that their natural diet consists mainly of meat and they have a limited ability to digest plant-based foods. Therefore, while blackberries can be a healthy treat for cats, they should not replace the essential nutrients that cats need from animal sources, such as protein, taurine, and arachidonic acid.

Moreover, some cats may have allergic reactions or digestive issues when eating certain fruits or vegetables, including blackberries. Symptoms of such reactions may include vomiting, diarrhea, lethargy, or skin rashes. If your cat shows any signs of discomfort after eating blackberries, you should stop feeding them this fruit and consult with a veterinarian.

Benefits of Feeding Blackberries to Cats

As mentioned earlier, blackberries contain several nutrients that can benefit cats, such as:


Blackberries are high in fiber, which can help regulate cats’ digestion and prevent constipation, hairballs, and other gastrointestinal issues. Fiber also promotes the growth of beneficial gut bacteria, which can boost cats’ immune system and reduce inflammation.

Vitamin C

Blackberries are a good source of vitamin C, which is an antioxidant that can protect cats’ cells from damage caused by free radicals. Vitamin C also supports collagen production, which is important for cats’ skin, bones, and blood vessels.


Blackberries are rich in water content, which can help cats stay hydrated and prevent urinary tract infections and other kidney-related problems. Adding blackberries to cats’ diet can be especially beneficial for cats who don’t drink enough water or who have a history of urinary issues.


Feeding blackberries to cats can provide them with a new taste and texture experience, which can help prevent boredom and encourage them to eat a varied diet. Variety in a cat’s diet can also prevent nutrient deficiencies and promote overall health.


Blackberries contain antioxidants, such as anthocyanins and polyphenols, which can have anti-inflammatory and anticancer properties. While more research is needed to determine the specific effects of these antioxidants on cats, it’s possible that they can provide some health benefits.

Risks of Feeding Blackberries to Cats

While blackberries can be beneficial for cats in moderation, there are also some potential risks to be aware of:

Digestive issues

Some cats may have difficulty digesting blackberries, especially if they are fed too many or if they are not used to eating fruits or vegetables. Eating too much fiber can cause diarrhea, bloating, or abdominal discomfort in cats, which can lead to dehydration and electrolyte imbalances. To avoid these issues, it’s recommended to introduce blackberries slowly and in small amounts, and to monitor your cat’s response.

Sugar content

Blackberries contain natural sugars, such as fructose and glucose, which can contribute to weight gain and diabetes in cats if they are consumed in excess. It’s important to limit the amount of blackberries you feed to your cat and to balance their diet with protein and fat sources.


Like many fruits and vegetables, blackberries may be exposed to pesticides during their growth and harvesting process. While the risk of toxicity from pesticides in small amounts is low, it’s recommended to choose organic or locally-grown blackberries whenever possible to minimize exposure.

Choking hazard

Blackberries have small seeds that can pose a choking hazard to cats, especially if they are not chewed properly. It’s recommended to remove the seeds or to mash the blackberries before feeding them to your cat, or to choose seedless varieties.
