What are the health benefits and risks of feeding guinea pigs apples?

Can Guinea Pigs Eat Apples?

Yes, guinea pigs can eat apples! But they shouldn't eat them in abundance and must be prepared appropriately.

Health Benefits Of Apples

First, let's talk about why you might want to feed your guinea pigs apples in the first place. What nutritional benefits might an apple have for your pet?


Apples are a great source of Vitamin C, E, and many types of Vitamin B. These are essential for immune system function and protein metabolism. Guinea pigs, in particular, need a large amount of Vitamin C, and a deficiency of Vitamin C in guinea pigs can lead to scurvy.


Apples contain an abundance of polyphenols, which is a key group of antioxidants. The job of antioxidants is to protect your cells from the free radicals that can lead to chronic health conditions.

Dietary Fiber

Apples are high in both water and dietary fiber, making them both hydrating and satiating. A guinea pig's natural diet needs large amounts of dietary fiber.

The Downside Of Guinea Pigs Eating Apples

It's important to give your guinea pig a healthy rotation of leafy greens, fresh fruits, and raw vegetables daily. However, it's equally important not just to offer one type of fruit or vegetable too frequently. A guinea pig's health will be negatively affected if they eat apples daily.

High Sugar Content

In the wild, a guinea pig's diet mostly consists of grass and hay. Fresh fruits contain considerably more sugar than either of these! It won't take many apples for a guinea pig to consume entirely too much sugar. Only feed apples to your guinea pig in moderation!

Toxic Seeds

Apple seeds contain a powerful poison known as cyanide. Eating too many apple seeds can pose a potential risk to a guinea pig. When feeding an apple to a guinea pig, apple seeds should be removed.


Some apples are slightly acidic and can be harmful to guinea pigs. Avoid any sour-tasting apples and opt for sweet and plain-tasting red apples.

What Is The Best Way For Guinea Pigs To Eat Apples?

The most important part of feeding apples to your guinea pig is to be careful with the portion size and the frequency. Apples should not be given to your pet more than 2 or 3 times a week as the pet's main diet should be guinea pig pellets.

Guinea pigs generally love to eat apples, so you need to determine how much apple is appropriate for your guinea pig. Small guinea pigs should only have one apple slice at a time, and larger guinea pigs can enjoy two apple slices as a serving size. Guinea pigs love apples and readily overeat them, so it's up to you to ensure your guinea pig only eats an appropriate amount of apples!

Before giving a guinea pig apples, be sure to wash the apple thoroughly. Most apples found in the grocery store have a waxy coating on the peel that will need to be washed off using warm, soapy water. Rinse off the soapy water with white vinegar, then let the fruit dry. Even if you get your apple directly from an apple tree, it's best to wash it to remove any pesticide residue.

After cleaning the apple, cut it into thin, wedge-shaped sliced. Take care to remove any seeds!
