Can Pet Mice Eat Eggs – A Full Guide

Eggs are easily one of my favorite foods, one of nature’s great gifts!

It’s always nice to share some of our favorite foods with our pets, but that always comes with a little risk.

Before feeding your pet any new food, it’s important to check whether it’s something they can eat, and whether they’ll get any nutritional benefit from it.

So that’s what I’ll explore in this article; do mice even like eggs? And more importantly, are eggs safe for your pet mouse to eat?

I’ll run through everything I know about mice and eggs.

Can mice eat eggs? Can mice get any health benefits from eggs and are there any health risks for mice eating eggs?

Mice can eat eggs. Mice are omnivores, which means they eat both plant and animal based foods. There are many health benefits mice can get from eating eggs, but eating too much egg also poses some health risks.

I’ll first go into detail about the benefits and risks of eggs, then I’ll answer some frequently asked questions about eggs and mice, including how much egg I would recommend mice can eat.

Health benefits of eggs for mice

Before I dive in, most of the good stuff in an egg comes from the egg yolk.

Whilst both the white and yolk are safe to eat for mice, and both have benefits, they will get the most nutrition from the yolk.

Raw white is not safe for mice to eat, I’ll come to that later in the article.

Vitamin A

This is the vitamin that you’re parents told you would let you see in the dark, the one packed into carrots.

Well, it’s also abundant in eggs and it really does help support eyesight.

It is also great for young mice as a vitamin A deficiency can actually stunt growth. On top of that, it helps to support god immune and cell function.


You may not have heard of it but Riboflavin is also a vitamin found in eggs (Its other name is vitamin B2).

It will help your mouse maintain an effective metabolism to get the most energy out of its food.


Another one of the B vitamins (B9), and also known as folic acid.

This vitamin also helps with a mouse’s metabolism and supports the integrity of their cell membranes.

A folate deficiency can lead to cell structures weakening.

Cobalamin (Vitamin B12)

The last of the B vitamins on this list, vitamin B12 also known as Cobalamin.

This one is important to maintain a healthy nervous system and good cognitive function.

It’s also important for good intestinal health and the growth of red blood cells.


This mineral is vital for the formation of red blood cells and hemoglobin.

Those, in turn, are responsible for carrying oxygen and nutrients throughout the body.


A trace mineral, Selenium is essential for the proper function of the thyroid gland and immune system of a mouse.

It has also been credited with a range of other benefits such as acting as an antioxidant and improving joint health.

Fatty Acids

Created once the fat of the egg has been broken down into fatty acids.

This is then absorbed by the blood and helps maintain healthy skin and coat, creating that nice shiny fur.

Fats are important in a mouse’s diet but of course, too much fat can be a bad thing.

Health risks of eggs for mice

Eggs are a great source of all types of nutrients, but like everything, if your pet mouse eats too much it can have negative effects too.

Luckily these effects aren’t too serve in eggs and they are a relatively safe treat for your mouse.

Weight gain

Eggs contain quite a lot of calories relative to their size.

If you were to feed your pet mouse egg on a daily basis, even in small amounts, they would be very likely to gain excess weight.

That’s the main reason eggs should always be considered as a treat for a mouse, rather than as part of a standard diet.

Biotin deficiency (from raw egg white)

This is only an issue if you’re feeding your mouse the raw white of an egg.

That’s quite unlikely as it’s going to be a messy way to feed your mouse, but it’s worth knowing about because it can be dangerous.

The raw white contains a protein called Avatin. Avatin binds with Biotin, preventing your mouse from absorbing it and leading to a Biotin deficiency.

Impacts can be anemia, dry hair or coat, skin lesions and lethargy.

Once the egg white is cooked it’s perfectly safe.

Can mice eat eggshells

Mice can eat eggshells and they are a very good source of calcium.

The main danger is how sharp eggshells can be, there is a chance your mouse might cut their mouth on a sharp piece of eggshell.

To avoid that entirely you can grind the eggshell up into a powder and add it to their food.

That means they can get the calcium hit without any risk of cutting their mouth.

Don’t give your mouse excessive amounts of eggshell though as too much calcium can thicken the urine, which can lead to urinary tract infections.

Can mice eat boiled eggs

Boiled eggs are safe for a mouse to eat and they are a great source of nutrition.

This is probably the best way to prepare an egg for your mouse, but just be sure not to give your mouse boiled egg too often as they could easily begin to gain weight.

They can even eat the eggshell too, although it does slightly increase the risk of choking.

Just remember that a freshly boiled egg can take quite a while to cool down, you should let the egg go cold before giving it to your mouse.

Can mice eat raw eggs

Mice can only eat the yolk of raw eggs. The white of a raw egg can cause biotin deficiency so it shouldn’t be given to your mouse.

However, I would’nt generally adivse giving your mouse raw egg simply because of how messy it could be.

The egg could easily get tangled in their fur, and it certainly wouldn’t be wise to give it them in their cage as raw egg and bedding would not make a good mix.

If you’re going to feed your mouse raw egg, I would definitely advise doing it outside of their cage, on top of an easily cleanable surface.

Can mice eat fried eggs

Most fried eggs will be bad for mice.

The added oil will not be good for your mouse’s health and the excess fat can lead to weight gain.

However, there are ways to cook an egg in a similar way without any added oil.

To get the same effect, you can bake a sunny side up egg in the oven with no oil, that’s what I do.

That gives the same effect but is perfectly healthy for your mouse (and you).

Can mice eat scrambled egg

Mice should not eat scrambled egg if it has been made with butter, milk or any other added ingredient such as salt.

Scrambled eggs are usually prepared with other ingredients which will not be healthy for a mouse.

Whilst milk might not seem unhealthy, pretty much all mice are lactose intolerant to some extent so it won’t do their digestive system any good.

So unless you cook your scrambled eggs using no other ingredients at all then I wouldn’t recommend feeding them to your mouse.

Can mice eat poached egg

Mice can eat poached eggs.

Just like boiled eggs, you should be sure the egg has cooled down before giving it to your mouse.

It’s also a good idea to add a splash of cider vinegar to the poaching water.

Not only does it help bind the egg together, but cider vinegar is also good for your mouse in small quantities as it can help reduce inflammation.

How much egg can a mouse eat

Despite all their nutritional benefits, there is a lot of fat in eggs and eating too much can quickly lead to weight gain.

You should only feed your mouse egg as a treat occasionally. I would recommend no more than half an egg per week.

That way they will get all the nutritional benefits but shouldn’t suffer from weight gain.

A final note – All mice are individuals

In general, eggs are great treats for mice, just don’t feed them too much and watch out for the raw white and they will get lots of health benefits.

However, some mice will be more sensitive to certain foods than others, and just because most mice can eat eggs with no problems doesn’t mean your mouse definitely will.

Older mice especially can be more prone to digestive issues.

So, whenever you give your mouse a new food, including eggs, monitor them for a couple of days to see if you notice and symptoms of digestive problems.

They are quite hard to spot in mice but two you can see are diarrhea and a noticeable decrease in their activity levels.

If you are at all concerned then I would recommend you stop feeding them eggs and find another treat for them, egg might just not sit well with their stomach.
