The short answer is this: Mice can definitely eat blueberries in small quantities and they can actually be beneficial. As long as you keep the precautions mentioned in this article in mind before you feed there should be no problem at all.

Can and should mice eat blueberries?

To find out whether mice can and should eat blueberries it’s a good idea to take a closer look at what exactly a blueberry contains. 3.5 ounces (around 100 grams) of blueberries contains the following macro-nutrients:

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

As you can see, blueberries are very low in calories and fat. That’s good news because mice don’t need a whole lot of fat and calories in their diet. However, these juicy little berries are also quite rich in sugar which means that they should not eat too many of them.

But that’s not all. Blueberries are also a great source of vitamins and minerals! They’re especially rich in vitamin K1, vitamin C, and manganese while containing smaller amounts of vitamin E, vitamin B6, and copper. Furthermore, blueberries are an amazing source of antioxidants.

On the whole, blueberries do not contain anything that’s toxic to mice so they can definitely eat them. In fact, they contain several essential nutrients that your mouse can benefit from having in its diet.

Benefits of blueberries for mice

Studies have been done that show that mice benefit from having blueberries in their diet. For instance, this study has shown that blueberries can significantly improve your mouse’s memory.

Precautions when feeding blueberries to mice

So, now you know that blueberries are beneficial for your mouse to have and you might be tempted to rush to the fridge, grab some blueberries and feed them to your mouse. Hold up a moment and read these precautions before you feed.

  1. Do not overfeed. While blueberries are good for your pet mouse in moderation you should be careful that you do not overfeed them. As previously mentioned, blueberries are high in sugar and too much sugar is not good for your mouse. Not only that, but mice need a varied diet that consists of many different kinds of foods to ensure they get all the nutrients they need.
  2. Introduce slowly. It’s a well-known fact that mice can get an upset stomach by sudden changes in their diet. Therefore, it’s important that you introduce them to new foods slowly. Start by giving them a small amount of the new food to see how they react to it. If they’re all good you can increase the amount you give them next time.
  3. Wash before feeding. It’s a sad reality that most of the produce in our modern world is contaminated with pesticides. These pesticides aren’t good for our pets so it’s recommended to wash the berries before feeding. Science shows that the ideal way to get rid of pesticides is by soaking the berries in a mixture of water and baking soda and then rinsing them with tap water.
