A well-balanced diet is essential in keeping a guinea pig happy and healthy, so it’s important to be informed about their nutritional needs. Guinea pigs are omnivores that require a high-fiber diet. While they can eat some fruits, like apples, they mostly thrive on grasses, hay, and vegetables.

Giving treats can be a great way to bond with your guinea pig, but it’s important to feed them treats in moderation. Your guinea pig may enjoy eating an apple, but it should only be given as an occasional snack.

Can Guinea Pigs Eat Apples?

Guinea pigs can eat apples as a special treat, but they shouldn’t be incorporated into their regular diet. There are some health benefits found in apples 1. For example, they’re a great source of vitamin E, vitamin B1, and antioxidants. Apple peels are also high in fiber.

Guinea pig owners must be mindful of the amount of sugar their guinea pigs are taking in, particularly from food they are not naturally adapted to. Guinea pigs digestive tracts aren’t designed to process significant quantities of sugar, and too much sugar can disrupt their gut flora and cause gastrointestinal issues 2.

How to Safely Feed Your Guinea Pig Apples

Your guinea pig can safely enjoy eating apples as occasional snacks once or twice a week. They shouldn’t eat more than a 1-inch apple slice in one sitting. If it’s your guinea pig’s first time eating an apple, start with an even smaller piece. Guinea pigs tend to have sensitive stomachs and can get an upset stomach if they eat too much of a type of new food, so play it safe and give your guinea pig a small slice and work your way up to increase the amount in increments.

Make sure only to give your guinea pig the peel and the flesh of an apple. Apple seeds can be a choking hazard, and they contain trace amounts of cyanide, so be sure to remove any seeds before offering your guinea pig this treat 3.

Wash the apple thoroughly before slicing it and feeding it to your guinea pig. Apple skins naturally produce their own wax, but some harvested apples may have an additional coat of wax sprayed on them to prevent them from drying out. This wax is edible, but your guinea pig may have a hard time digesting it if it has a particularly sensitive stomach.

Healthy Diet for Guinea Pigs

It’s important to remember that guinea pigs are herbivores with diets that mainly consist of grasses, hay, and leafy vegetables. Grass hay should take up the majority of a guinea pig’s diet, and your guinea pig’s meals can consist of up to 75% grass hay. Not only are grasses easily digestible, but they also help maintain guinea pigs’ ever-growing teeth. Grasses help wear down the teeth every time guinea pigs gnaw on them. Some of the most popular types of hay for guinea pigs are Timothy and orchard hay grass. Do not feed your guinea pig lawnmower clippings as they can also make them ill.

Your guinea pig will also benefit from eating food pellets specifically formulated for guinea pigs. These pellets will contain other essential nutrients for guinea pigs, including vitamin C. It’s important to give your guinea pig the right amount of pellets because overeating can cause excessive weight gain.

Guinea pigs will also appreciate eating an assortment of fresh vegetables. Just be mindful of the kinds of vegetables you feed your guinea pig because some may cause digestive issues. Stick to romaine lettuce, dandelion greens, parsley, cilantro, and carrots. Make sure to introduce your guinea pig to new vegetables slowly to avoid upsetting its stomach.


Apples and a selection of other fruits are safe for guinea pigs to eat, but they’re not meant to be a part of their main diet. Guinea pigs thrive on grass, hay, and vegetables, and apples should only be given as a special treat.

Sticking to a healthy diet will help your guinea pig live a long and happy life and avoid any digestive issues and weight gain. So, refrain from giving your guinea pig too many snacks and treats. Your guinea pig will be much happier without experiencing an upset stomach than getting sick from eating too many sweet treats.
