Is there anything bad in blueberries for rats?

Blueberries are a fruit that’s native to North-America. Now, don’t worry, I’m not going to bore you with the long, eventful history of this berry. That’s not what you’re here for.

Instead, I’ll just go over what’s inside the berry so we can get an idea of what we’re putting in our rat’s mouth.

3.5 ounces of blueberries contains the following:

  • 84% water
  • 57 calories
  • 14.5 grams of carbs
  • 10 grams of sugar
  • 2.4 grams of fiber
  • 0.3 grams of fat
  • 0.7 grams of protein

Now, those are the macronutrients in the fruit. As you can see, they’re mostly made up of water. Because of this, they’re a way to quench your rat’s thirst on hot days. Of course, it’s not a substitute for drinking water, but it does aid their water intake.

On the other hand, since there’s so much water in blueberries you do have to be careful not to overfeed your rat. Too much water in your rat’s digestive system can lead to diarrhea, and since these fruits contain quite a lot of it, you have to be careful to feed it in small quantities.

Luckily, they’re very low in fat. Because of this, these berries are quite low in calories, and there’s not much risk of weight gain.

On top of all of this, blueberries are a great source of fiber.

However, the list above only goes over the macronutrients. Where blueberries really shine is their micronutrients. Let’s take a closer look.

Micronutrients

Blueberries are very rich in many vitamins, minerals, and antioxidants.

Vitamin K1 is mostly used to help with blood clotting, but it’s also important for bone health. Blueberries are exceptionally rich in this vitamin which is great news for your rat.

Also, they’re a great source of manganese and vitamin C. Further, these fruits contain small amounts of vitamin E, vitamin B6, and copper.

Where these berries really outdo most other fruits is in their antioxidants. They contain more antioxidants than almost any other fruit and this is where their status as “superfood” comes from. Antioxidants are important to help prevent age-related diseases such as heart disease and cancer.

So are blueberries good for rats?

Most definitely! The science is clear here, blueberries are an amazing fruit to give to your rat. There are many studies that prove the beneficial effects these berries have on your rat’s wellbeing. For example, did you know that blueberries can prevent, and even reverse, age-related mental decline in rats?

And that’s not all, these berries are not only great for your rat’s brain, they’re also great for their little heart.

All in all, blueberries are among the healthiest fruits that you can include in your rat’s diet. However, moderation is key. While they are very good for them, too much of a good thing can turn it into a bad thing. Make sure to give them properly sized portions.

How many blueberries are safe for rats to eat?

So, now that we’ve taken a closer look at what’s in these fruits and concluded that they’re safe for rats to consume you might wonder how of them they can eat, and how often.

The ideal rat diet consists of about 20% of fresh fruits and vegetables by weight. However, this does not mean that you can make 20% of their diet consist purely of blueberries; they need a balanced diet with many different fruits and vegetables.

Nevertheless, blueberries are a great inclusion and can definitely be a part of it. You can safely feed your rat one of these berries every other day without any adverse effects.

A good diet is important

Having a healthy and happy rat starts with them having a good diet. Here’s what your rat needs on a daily basis:

  • An unlimited amount of fresh, clean water in their water bottle. Make sure that you clean and refill their bottle daily.
  • Pellets should be the majority of their diet and should make up around 75-80% of their food intake.
  • Fresh fruits and veggies should make up the remaining 20-25%.
  • The occasional treat can consist of meat, eggs, or even better, specialized rat treats that you can buy online.
  • Be careful with their food intake, rats are small animals and very easy to overfeed, as a result, they can easily become overweight which leads to all kinds of problems.

How to feed blueberries to your rat

Feeding your rat blueberries is very easy. The only thing that you have to make sure you do is that you wash them properly. Fruits are notorious for having quite a lot of pesticides on the skin, which is not good for your rat to ingest. Washing them in baking soda is ideal to get rid of the pesticides, but washing them under running water for a couple of minutes will also do.

Once they’re properly washed you can simply give them the berry whole; there’s no need to cut it up and there are no seeds to remove.
