Can Cats Eat Blueberries?

Can cats eat blueberries?

Cats are known to be carnivores, but that does not mean that they cannot eat other foods as well.

The short answer is yes, cats can eat blueberries.

In fact, blueberries are non-toxic to cats and are one of the few human foods they can eat safely.

However, it is important to note that berries are not a substitute for an appropriate diet and should not be fed to your cat as a replacement for their regular food.

Cats are still carnivores and require protein from meat in order to thrive.

It is important not to overfeed your cat with berries because it can upset their stomachs or give them diarrhea.

Feed your cat berries sparingly and only in moderation so that they get the nutrients they need from their regular diet as well.

If a Cat Eats Too Many Blueberries, What Can Be the Effects?

Can cats eat blueberries?

It is advised that you give your pet blueberries sparingly. Blueberries have carbs, whether they are in the form of fructose or fibers.

One thing that your pet should absolutely not do is eat excess carbohydrates. When they eat carbs, the main issue they face is weight gain, as well as diabetes as a result of excessive sugar consumption.

The downside of excessive sugar consumption on a cat:

  • Diabetes
  • Pancreatitis
  • Obesity
  • Arthritis and mobility issues
  • Heart problems


Diabetes in cats is one of the most common long-term feline health conditions. It’s caused when your cat eats too much sugar and their blood glucose levels get too high

If this goes on for a long time, it can eventually cause serious damage to the kidneys, heart, and other organs.

Cats with diabetes suffer from the following symptoms:

  • Vomiting
  • Lack of appetite
  • Excessive thirst
  • Frequent urination
  • Weight loss


Pancreatitis is a painful and life-threatening condition in which the pancreas becomes swollen and inflamed.

When cats eat large quantities of carbs, their system is overloaded with sugars, which may make their system unstable.

To fight this, the pancreas releases a hormone called insulin that helps keep the glucose level balanced.

As a result of this extra burden on the pancreas, it may develop pancreatitis, which can be fatal if left untreated.


Cats have an increased susceptibility to obesity when given sugary treats or an excessive amount of food that is not balanced.

Their caloric requirement is less than dogs and other mammals which means that they don’t need as many calories per day in order to maintain a healthy weight.

To prevent obesity, feed your cat a balanced diet and avoid sugary treats or foods that are high in fat or carbohydrates.

Arthritis and Mobility Issues

It is possible for a cat to develop arthritis and mobility issues as a result of excessive consumption of carbohydrates.

The reason behind this is that carbohydrates can lead to obesity which in turn can lead to lethargy in the animal. If the animal becomes lethargic it will not consume the necessary calories.

Lack of activity and calorie consumption can lead to joint degeneration and arthritis in the cat. In addition to arthritis, mobility issues may arise from a lack of exercise due to being overweight.

Heart Problems

Cats have a predisposition to heart problems because of their nature to consume too many carbs and not get enough exercise due to their indoor lifestyles.

Obesity also plays a role in heart issues because the heart has to work harder due to the weight of the animal.

Neutered and domesticated cats are particularly susceptible to these problems because they are less active than their counterparts that are allowed outdoors.

The signs of heart disease in cats can include:

  • Difficulty breathing
  • Increased respiration rate
  • Seizures
  • Stunted growth
  • Acute paralysis of the hind legs

Is it Possible for Cats to Have Allergic Reactions to Blueberries?

It is very rare for cats to be allergic to blueberries, but it does happen. Signs of an allergic reaction to blueberries in cats include:

  • Difficulty breathing
  • Sneezing
  • Coughing
  • Vomiting
  • Diarrhea
  • Runny nose
  • Watery eyes
  • Itching
  • Skin rashes
  • Face swelling

Immediately contact your veterinarian if your cat shows symptoms of being allergic. However, if your pet doesn’t have any allergies or other health problems that would cause a problem with eating blueberries (i.e., pancreatitis), then you can probably feed them this tasty fruit on occasion.

Blueberries for Cats: How to Introduce Them?

If your cat has never eaten blueberries before, here are some tips to help them safely explore the flavor of this new food.

Consult Your Veterinarian

You should always consult your vet before offering your cat any new food, despite the fact that it is harmless for cats.

Calculate the Portions

Depending on your cat’s nutritional needs, weight, and overall health, you can determine how many blueberries he or she needs over a period of time. It is never advisable to exceed 10% of your cat’s total daily caloric needs with treats or snacks.

Prepare the Berries

This process starts with thorough washing, detaching the stems, and cutting the berries into smaller sizes before serving.

Monitor Your Cat

Cats are typically able to eat blueberries, but it is possible for them to experience gastrointestinal upset and diarrhea.

After feeding your cat blueberries, monitor their health and behavior for any signs of distress. If you notice any signs of discomfort, stop feeding the cat blueberries immediately.

Is it Necessary to Include Fruits in a Cat’s Diet?

Can cats eat blueberries?

It is often believed that cats need fruit in their diet because it provides a source of carbs and vitamins and minerals that meat cannot provide.

However, this isn’t the case because obligate carnivores can only derive nutrients from meat-based products and fruits are not necessary for their diet.

In general, treats or snacks should not comprise more than 10% of your cat’s daily diet, and fruit should only be offered occasionally as a treat.

Safe Fruits and Vegetables for Cats

Although cats require a lot of protein in their diets, they can also consume small amounts of fruit and vegetables, such as:

  • Cantaloupe
  • Pumpkin
  • Bananas
  • Apples
  • Spinach
  • Strawberries
  • Carrots

Healthy Protein Snacks for a Cat

The nutritional benefits of protein snacks, like cooked chicken or tuna mixed with their favorite wet food, will provide your cat with the nutrition he or she needs without the sweetness of human treats.

You have many different options for a protein snack, for example:

  • Chicken
  • Lean beef
  • Shrimps and prawns
  • Sardines
  • Lamb
  • Cooked eggs
  • Salmon
  • Mackerel
  • Tuna

 Key Takeaways

  1. Cats can eat blueberries, but they should not be the only food you feed them.
  2. Though it is true that blueberries do not typically make cats sick, there is sometimes a rare occurrence where the berries can produce an allergic reaction.
  3. The carbs in blueberries may cause certain health problems in cats if they consume too many of them.

Importance of Pet Insurance

Pet insurance is a great way to protect your animal’s health. It can be hard to predict when an accident will happen, but with pet insurance, you’re covered.

There are a few different types of plans depending on your needs, and it only takes minutes to get coverage for your pet.

Some pet insurance companies will even cover 100% of veterinary expenses. So make sure to choose the best pet insurance plan for your furry friend.

Once you have a plan in place, vet bills will never be too high because they’ll already be covered by the policy.

It’s important that we all take care of our animals’ safety and well-being so they can enjoy their lives just as much as we do ours.

Why is Lysine so Important for Your Pet?

Lysine supplement

Protect your pet’s immunity!

Have you noticed that your cat is coughing, sneezing, and having rapid breathing? Or maybe he/she has been scratching more than usual?

These are all signs of a weakened immune system. One way to prevent this from happening is by using lysine supplements.

Lysine plays a key role in your pet’s immunity because it helps to regulate the immune system.

Without enough lysine, your pets will be more susceptible to illness because their immune system can’t fight off infections as efficiently.

When they are sick, they will also be less able to absorb nutrients and make use of other supplements that can help them feel better.

Give your pet the support they need. Our Lysine supplement provides essential amino acids to help support a strong immune system.
