Can Mice Eat Bread? [Is It Safe And Should We Feed It?]

Serving your pet mouse the right food is crucial for their health. However, it is not always obvious as to what foods are best and which ones can be problematic and should be avoided. A lot of owners often question what is most ideal to feed as a snack.

So, can mice eat bread? Mice can eat bread, but should only consume a small amount, infrequently. Bread should never form as a staple and be the predominant food source of their diet. While bread is generally safe, too much in one meal can lead to bloating, diarrhea, vomiting and some other gastrointestinal problems. Bread can also be a choking hazard, so cutting it into small pieces, toasting or soaking in water is generally recommended.

While bread is not the most ideal foods, it does serve as a tasty treat once in a while if prepared appropriately. Let us now take a closer look at why you should limit bread, how you can feed some, along with some other safe and healthy snacks for your pet.

Mice and Bread

Mice can eat bread, and generally enjoy doing so. It is considered a safe food, but only when given in small amounts and in moderation.

If you want to offer bread, it is preferable to seek out an organic, high-quality, minimally processed option.

Organic bread will be free from any pesticides or synthetic fertilizers that would have been used in the growth of the grain. It should also be more abundant in nutrients, antioxidants, vitamins and minerals that can help to serve the health of your mouse.

That being said, mice can eat all types of bread; whether it is a white, wholemeal, or whether it is made from a specific type of grain, e.g. rye.

You will need to consider that bread ranges in density, fiber content and how easily it is digested. Therefore, you will need to prepare the bread accordingly.

All breads should be cut into very small pieces prior to offering. However, some types of breads may require additional crumbling.

Irregardless of the type of bread, it is generally advised to soak make the bread as small and manageable as you can for your mouse. Soaking bread in water (or even milk) is a great idea, and makes it particularly easy for them to consume, while minimizing the risks of choking.

Also be sure to feed a small amount of bread at a time.

If you were to give a large amount of bread to your mouse, they are likely to experience adverse health effects.

Too much bread can result in bloating, diarrhea, vomiting and some other gastrointestinal problems. This is why it is so important to observe your mouse and monitor them after any feeding.

Ultimately, bread can be safe, enjoyed and provide some nutrition to your mouse if you are careful.

Mice are considered opportunistic omnivores; so a chance to access this food will likely be enjoyed.

If you are yet to include bread in the diet of your mouse, you should look to introduce it slowly. Making a drastic or sudden change can lead to digestive upset and issues. Therefore, start with very small amounts and work up gradually over time.

Equally, its a good food to scatter around the cage. This will enable your mouse to partake in their natural foraging behaviors. Wild mice find food by foraging and spend a lot of time actively searching for food.

As owners we can replicate this with our pets, boosting their well-being and preventing boredom.

Do Not Forget Fresh Water

Mice are heavily reliant on drinking water; deprivation can lead to death even in short periods of time without access.

Therefore, it is essential as an owner to provide multiple clean sources of water. While some water and hydration will come from their food; we must install specific items in their cage.

Water in bottles with metal sipper tubes should be installed. From there, we should check them daily to ensure they are not leaking or blocked.

All water should be changed in these bottles daily, and we should also look to clean the ends at the same time too. This will help prevent contamination.

Other Treats To Serve Your Mouse

Pet mice, being opportunistic omnivores, thrive on a balanced and varied diet. While a high-quality commercial pellet feed should ensure they get all of the nutrients they need, regular access to fruits and vegetables and occasional and small servings of cereals and grains can be included.

This will not only help you to replicate the diet of a wild mouse; whom are known to consume a variety of seeds, grains and other plant based matter. But, it will also help to treat your mouse and keep their diet interesting.

So outside, small servings of bread, here are some other treats you could offer your mouse:


  • Apples (Seeds removed)
  • Pears
  • Banana
  • Melons
  • Stone Fruits (Stone removed)
  • Berries

Foods To Never Feed Your Mouse

There are certain foods that you should never feed to your pet mouse. They are either outright harmful and toxic or they do not provide any nutritional benefit.

So, let’s take a look at some of the main ones so you know what to avoid if you do not know so already.

  • Grapes (poisonous)
  • Raisins (poisonous)
  • Rhubarb (poisonous)
  • Walnuts (poisonous)
  • Lettuce (nutritionally devoid and can result in diarrhea)
  • Citrus Fruits (Oranges, Lemons, Limes and Grapefruit)

Items to Chew

Mice are renown for their chewing and gnawing. In fact, its a natural behavior that helps to keep their teeth healthy and to prevent boredom.

As an owner, we can support them by offering:

  • Cardboard
  • Hay Cubes
  • Coconut Shells
  • Pumice Stone
  • Seagrass
  • Untreated Softwood (e.g. Elm, Willow and Yucca)


Mice can eat bread, and generally enjoy to do so when it is available. This is likely due in part to their nature and being opportunistic in their feeding habits and behaviors.

As owners, we must be careful and take responsibility – being sure to select and prepare foods safely and appropriately.

For bread, this means seeking out higher quality bread where possible, cutting it up into small pieces, soaking in water and scattering it around the cage to promote natural foraging.

Aside from this, providing them with a high quality pelleted feed and a number of other wholesome snacks (like specific fruits and vegetables referenced above) will go a long way to promoting the health and longevity of your mouse.
