Can Cats Eat Blueberries? Benefits, Safety, and Tips for Felines
An occasional fresh berry adds a playful, hydrating twist to your feline’s treat routine.
Can Cats Eat Blueberries?
Curious if cats can eat blueberries? The simple answer is yes: blueberries are non-toxic to cats and, in moderation, can be a fun and occasionally beneficial treat for your feline companion. However, while safe for most healthy cats, blueberries should never replace a balanced, species-appropriate diet.
Blueberries: Are They Safe For Cats?
Blueberries are not listed on any veterinary poison control lists and do not contain substances that are commonly toxic to cats (such as grapes, onions, or chocolate). This makes them generally safe as an occasional treat for healthy cats.
Exceptions apply: Cats with certain health conditions—including diabetes, kidney disease, or sensitive digestive systems—may not tolerate the natural sugars and fiber in blueberries and could experience digestive upset if given too many.
For healthy cats, a berry or two every so often is harmless, but always observe when introducing any new food.
- Blueberries are safe for healthy cats in small amounts
- Monitor for any signs of digestive upset, such as vomiting or diarrhea
- If in doubt, consult your veterinarian before adding new foods to your cat’s diet
Nutritional Profile of Blueberries
For humans, blueberries are considered a superfood, rich in vitamins, antioxidants, and essential minerals. But how relevant are these nutrients for felines?
| Nutrient | Per 100g Blueberries |
|---|---|
| Calories | ~38.8 kcal |
| Protein | 0.5g |
| Total Fat | 0.22g |
| Carbohydrates | 9.8g |
| Fiber | 1.6g |
| Sugar | 6.7g |
| Calcium | 4mg |
| Iron | 0.19mg |
| Magnesium | 4mg |
| Phosphorus | 8.1mg |
| Potassium | 52.4mg |
| Sodium | 0.68mg |
Blueberries are approximately 85% water, which can help keep your cat hydrated, particularly during hot weather (but should not substitute fresh water).
Do Blueberries Offer Any Health Benefits for Cats?
Blueberries are packed with antioxidants (substances that neutralize free radicals), fiber, and vitamins such as vitamin C, vitamin K, and potassium. While these nutrients provide clear health advantages for people, their impact on cats is much less pronounced.
- Antioxidants: May support immune health and joint health by reducing inflammation.
- Fiber: Can help with digestion, but excessive fiber may cause digestive disturbance in cats.
- Vitamins and Minerals: Blueberries contain vitamin C, vitamin K, manganese, and potassium. Cats, however, produce their own vitamin C internally and do not require extra from foods.
- Hydration: Due to their high water content, a couple of berries are a hydrating treat for cats (though they should not replace access to fresh water).
Nevertheless, cats are obligate carnivores: their bodies have evolved to obtain essential nutrients from animal proteins and fats, not from fruit or plants. As a result, the health benefits seen in humans eating blueberries do not translate directly to cats.
Should Cats Eat Blueberries?
While safe in moderation, blueberries should not become a staple of your cat’s diet. Veterinary nutritionists recommend limiting treats of any kind to no more than 10% of a cat’s daily caloric intake.
For most healthy felines, 1-3 blueberries per session is a suitable serving.
- Always feed blueberries plain and raw, not canned, sugared, or in baked goods
- Wash blueberries thoroughly before offering them to your cat
- Cut or mash berries to prevent potential choking, especially for kittens or small cats
- Avoid feeding blueberries to cats with diabetes or gastrointestinal sensitivities unless a vet approves

How to Give Blueberries to Your Cat
Introducing a new food? Do so gradually and observe for any adverse reactions.
- Wash blueberries well to remove pesticides or contaminants
- Cut large berries into small, manageable pieces
- Offer a single berry at first
- Supervise your cat when trying new foods
- If tolerated, offer up to two or three berries as a treat
If your cat shows no interest, don’t worry. Many cats are indifferent to fruit and may ignore the treat entirely. Since cats cannot taste sweetness, the intrigue may stem from texture or curiosity rather than flavor.
Potential Risks and Precautions
- Sugar Content: Blueberries are naturally high in sugars for their size. Large amounts can raise blood sugar and may exacerbate diabetes or cause digestive upset.
- Choking Hazard: Whole berries can be a choking risk for kittens or older cats. Always cut or mash before feeding.
- Diet Imbalance: Blueberries should not replace protein- and nutrient-rich foods designed for felines. Their primary diet should always be high-quality cat food.
- Gastrointestinal Upset: Some cats may develop diarrhea or vomiting if they eat more than a minimal quantity.
If you notice any symptoms—vomiting, diarrhea, lethargy, loss of appetite—after offering blueberries (or any new food), discontinue immediately and contact your veterinarian.
Will Your Cat Try Blueberries?
Every cat is unique. Some cats may play with or taste blueberries out of curiosity, while others may have no interest at all. It is common for cats to ignore fruit, as they lack the taste receptors for sweetness. Don’t be surprised if your feline friend turns up their nose!
Special Cases: When Blueberries Can Be Bad for Cats
- Pre-existing Health Issues: Cats with diabetes, kidney problems, or digestive issues should avoid blueberries unless their veterinarian approves.
- Allergies: Though rare, some cats may exhibit allergic reactions. If sneezing, lip swelling, or hives appear, avoid future servings.
- Processed or Flavored Blueberries: Do not offer your cat blueberries that are sweetened, flavored, or part of baked goods. Added sugars and fats are harmful.
What About Blueberry Extract in Cat Food?
It’s common to see blueberry extract among the ingredients in some commercial cat foods and treats. The good news: blueberry extract does not raise blood sugar levels in cats and is included in safe amounts. Products formulated for cats are generally tested for safety before use.
However, always check for the AAFCO (Association of American Feed Control Officials) statement to confirm nutritional adequacy.
How Often Should You Feed Blueberries?
Veterinarians and nutritionists agree: treats, including blueberries, should comprise no more than 10% of your cat’s daily calories. For the average adult cat, this equals roughly 1-3 blueberries at a time, fed no more than once per day and preferably several times per week, not daily.
Expert Advice: What Veterinarians Recommend
- Blueberries are fine as a rare treat for most healthy cats
- Do not force cats to eat blueberries—it’s normal for them to be uninterested
- If you are unsure about what other treats are safe or appropriate for your cat’s age, health, or weight, consult with your vet
- Never use blueberries (or any treat) as a substitute for a nutritionally complete cat diet
Pro Tips: Enriching Your Cat’s Mealtime with Healthy Treats
- Use blueberries as part of food puzzles or for training enrichment
- Try freezing a blueberry in an ice cube as a cool, fun treat in warm weather (only supervise and make sure your cat isn’t at risk of choking)
- Rotate treat options for variety, using fruits, vegetables, or commercial cat treats as approved by your veterinarian

Final Thoughts
Blueberries can be a fun, safe treat for most cats when offered sparingly.
