Can guinea pigs eat apples?

The core of the apple is rich in fiber and this is something that your guinea pig wants the most.

So, this part of the apple is beneficial for them. If you are curious that too much fiber can make them choke, then think about the hay.

They munch down hay all the time. In my house, if someone eats an apple, my piggie is always ready to share the food.

He always gets the call. If you heard someone saying that Apple seeds are not good for guinea.

 Then, this is because seeds contain a compound that changes into cyanide. This happens when seeds get crushed or chewed.

But this amount is so small that you need a sufficient amount of apple seeds to pose a danger.

But here I am assuring you that your guinea pig can eat seeds along with apple core. It will cause no ill effects.

Apple skin is also beneficial for guinea pigs. Even many nutrients are present in apple peel. So you don’t have to remove the skin.

Most of the apples available in the market are waxed. This doesn’t affect the health of your guinea pig. But organic unwaxed apples are a better option.

Don’t forget to wash apples before giving them to your piggies. Cooked apples are not good for guineas.

In their natural habitat, they don’t get cooked food. So, keep it natural and offer them raw fruits and vegetables.

Excess to everything is bad. Too much apple can be led to mouth sores in guinea pigs. It is more common in old guineas.

Apples are rich in sugar and don’t contain a high amount of vitamin C which is essential for guinea pigs.

So, nutritionally apples should be regarded as an occasional treat. You can feed them an apple. But in small amounts and not too often.

Nutritional value of apple

It is not wise to compare the needs of humans and guinea pigs. However, guinea pigs also need vitamins and other nutrients.

Apples are a good source of dietary fiber. Fiber is the nutrient that a guinea e needs the most.

Apple core is rich in fiber. In addition to fiber, the next most important vitamin for piggie is vitamin C.

Apple contains a sufficient amount of vitamin C. A few chunks of apple would be enough to fulfill the requirement of vitamin C.

Guinea pigs need almost 10mg of vitamin C per day. Otherwise, they will develop scurvy.

Moreover, apples contain certain types of vitamin B. These include vitamin b6, vitamin B12, thiamine, and riboflavin.

These improve the nervous system of your piggie.

Apple skin is also rich in fibers and other nutrients. So, don’t peel the skin before serving them.

It improves digestion and is healthy. Still, if you want to add more fiber to the diet of Guinea pigs. Then, consider adding apple leaves.

Apple leaves contain fiber as well as calcium that strengthen bones.

The other nutrients include iron, magnesium, sodium, potassium, phosphorus, and vitamin A. Moreover, Vitamin K, vitamin E, Folate, and Beta carotene are also present.

Vitamin C

According to sources, each 100-gram apple contains 4.6mg of vitamin C. It somehow fulfills some of the daily requirements of vitamin C.

Vitamin C is essential in guinea pigs. They cannot synthesize their vitamin C. So they depend upon dietary sources for this vitamin.

Vitamin C is important in various body functions. It maintains skin and joints. Moreover, it helps in the healing of wounds.

Extreme vitamin C deficiency can lead to scurvy.


Apple’s contain 2.4 grams of fiber per 100 grams. This is the same amount found in the banana.

Fiber is essential for a healthy digestive system. It flushes out certain toxins and undigested food particles.

It also helps the digestive system to run smoothly and maintain the balance of normal flora in the gut.

Dietary fiber is also beneficial in dental health. Apples are a good source of dietary fiber. But their main source is hay and pellets.
