Can Pet Mice Eat Apples – A Full Guide


Apples are one of the nation’s favorite fruits.

We know they are healthy for us, and most of us love the sweet taste.

But we also know that not everything that’s good for humans is good for our pets.

In this article, I’ll explore whether mice can eat apples and how much apple a mouse can safely eat.

If you’re thinking of giving apple to your mouse then this article is definitely worth a read!

The flesh of an apple is safe for mice to eat. However; you should never let your mouse eat apple seeds. Apple seeds are toxic and lethal in large enough quantities.

There you have it, apples are mostly fine but the seeds are very dangerous.

In the rest of the article, I’ll detail the main health benefits of apples, and answer many frequently asked questions about apple seeds and cores a how much apple you should feed your mouse.

Health benefits of apples for mice

Apples provide plenty of health benefits for mice.

As long as they don’t eat the seeds then apples are perfectly safe.

There are some risks if your mouse eats too much apple, and I’ll discuss those later, but now let’s look at the benefits.

Vitamin A

Vitamin A is the vitamin in carrots that your parents said would help you to see in the dark.

There’s actually a lot of truth in that, vitamin A does support good eyesight, and a vitamin A deficiency can result in ‘night blindness’.

It also helps to support a healthy immune system and is involved in the production and function of white blood cells.

White blood cells help to capture bacteria and other pathogens in the bloodstream.

On top of that, vitamin A works along with vitamin D, protein and calcium to help maintain strong bones, allowing for proper growth and development.

Vitamin C

Vitamin C helps to protect the body against cell and tissue damage as well as aiding the body to better absorb iron.

It also helps to produce collagen, that will lead to more healthy skin and bones for your mouse and aids with wound healing.

Fiber

Fiber is essential for healthy digestion. It has two categories, soluble and insoluble fiber.

Soluble fiber helps to control the blood sugar level of the body and aids in ridding the body of fatty substances such as cholesterol.

Insoluble fiber helps to keep the digestive system moving, it will add weight but also softens to your mouse’s stools which in turn will help the digestive system to work effectively.

Calcium

This is quite often overlooked but apples actually contain a good amount of calcium.

That’s going to be great for your mouse. Calcium helps to build strong bones and teeth, as well as thick fur with that lovely shiny look.

In addition to that, calcium also helps to ensure the blood clots effectively and helps to regulate muscle contractions, that’s important for vital bodily functions such as ensuring a strong regular heartbeat.

Potassium

Potassium is great for helping to maintain a well functioning nervous system.

It also helps to regulate muscle and heart contractions as well as preventing high blood pressure.

Potassium has also been shown to support bone and muscle strength as the body ages.

Health risks of apples for mice

Most fruits are going to have similar health risks for your mouse.

In small amounts, they can be great, but their sweetness comes from the high sugar content, and that will always pose a health risk if eaten in excess.

Excess sugar

Just like any fruit, the main reason your mouse will love the taste of apples is that it’s sweet.

That sweetness comes from sugar, apples are natural sugar but in excessive amounts, it can still be harmful to your mouse.

If your mouse consumes too much sugar then they are probably going to start gaining weight, as the excess sugar is converted into fat.

That’s going to cause all sorts of problems, such as high blood pressure and cardiac stress, your mouse will probably also become less active which will just add to the issues long term.

Excess fiber

Fiber is great for the digestive system, but too much fiber can start to cause digestive issues of its own.

An excess of fiber can block up the digestive system rather than helping to keep things moving.

Excess fiber can result in discomfort, constipation or diarrhea.

Digestive issues are never going to be nice for either your mouse or you!

Digestive issues will be even more of a risk if you feed your mouse the apple core, which contains more fiber than the rest of the apple.

Can mice eat apple cores

I would recommend not feeding your mouse apple cores.

A mouse will happily eat an apple core and they will probably be fine if they do.

But apple cores are much more difficult to digest than the softer apple flesh that I don’t really see the point in giving it to your mouse, it will just put excess strain on their digestive system.

Your mouse’s digestive system will much more easily be able to break down and extract all the nutrients from the surrounding apple.

Your mouse should be eating such small amounts of an apple anyway, that it doesn’t make much sense to give them the part that’s hardest to digest.

Can mice eat apple seeds

Mice can not eat apple seeds. Apple seeds are toxic to mice.

Apple seeds contain a chemical called Amygdalin, this is converted into Cyanide once chewed which is a well-known poison.

In fact, research has shown that around two cups of ground-up apple seeds could be fatally toxic to a human.

I think that’s quite amazing. Of course, two cups is a lot of seeds and is an unrealistic amount of a human to accidentally eat.

But remember that mice are so incredibly small compared to you.

I haven’t found a study on apple seeds specifically for mice. But it seems reasonable that it might not actually take that many seeds for a mouse to start feeling the toxic effects.

There might be four or six apple seeds in an apple core and personally I would be concerned if a mouse ate them all.

Can mice eat apple peel

Mice can eat apple peel. You do not have to peel an apple before giving it to your mouse.

The apple peel has a higher content of many nutrients than the rest of the apple, so it’s a great part for your mouse to eat.

An apple that still has its skin contains 332% more vitamin K, 142% more vitamin A, 115% more vitamin C, 20% more calcium and 19% more potassium than an apple which has been entirely peeled.

It’s usually recommended to try and avoid giving apples that have been sprayed in pesticides to your mouse.

In reality that is easier said than done, so if you can’t get hold of pesticide-free apples then just wash the apples as best you can before giving them to your mouse.

If humans are eating them they can’t be that bad for your mouse after all.

How much apple can a mouse eat

Apples are a treat for your mouse. As such they should only be given in small amounts and infrequently.

Apples should not be considered part of their normal daily diet.

I would recommend feeding no more than one apple slice to your mouse per week.

That will be plenty. Just think, that’s like eating an apple half the size of you every week!

It’s also a good idea to cut the apple up into little pieces that your mouse can easily handle.

A final note – All mice are different

You should still remember that some mice will find certain food more difficult to stomach than other mice.

Some mice may struggle to digest certain foods, especially older mice.

Wherever feeding your mouse a new food, including apples, always watch them for a day or so for any signs of digestive issues.

Digestive issues can be hard to spot in mice, but noticeable things could be diarrhea or a sharp reduction in activity levels.

If you notice any unusual symptoms or behavior it’s probably worth not feeding your mouse apples again and trying a different treat, their stomach just might not agree with it.
