Is eating apples good for guinea pigs?

You should not try to substitute treats, which in this case are apples, for your guinea pig’s actual meals. At all times ensure that they have fresh veggies and hay as their staple foods.

Apples are rich in vitamins and antioxidants. Their peels and core are filled with good fiber which assists in digestion processes.

Too much fruit will upset your furry ball’s stomach so keep to the small slices.


Apples are high in sugar which will lead to your guinea pigs becoming obese if they eat too much of them. An obese guinea is an unhealthy guinea pig.

How to feed apples to your guinea pigs

The first step should always be to scrub and wash them clean unless you plucked them from your apple tree. Even then, it is good to wash them.

Apples are part of the dirty dozen as they rank fourth as the most contaminated fruits. They are sprayed with a lot of pesticides as they are prone to pests.

This makes it vital to wash them carefully to avoid poisoning your pet. Some people prefer peeling them before feeding but the peels are nutritious for guinea pigs.

Cut your washed apple into smaller pieces and give your pet some slices. It’s good to start small if you are just introducing your pet to the fruit to avoid stomach upsets.

Keep a keen eye on the guinea pig for 12 hours to observe any reactions from the apples like diarrhea. If there is none and your pet likes the apples, keep giving them more, gradually increasing their amount.

If their stool becomes loose, reduce the amount given and reintroduce in smaller amounts. You could have given more than enough.

Always give the fruit once or twice a week. Sometimes your guinea pig will not like the fruit and they could even ignore it entirely.

Guinea pigs can eat apples and they love them because they are crunchy and sweet at the same time. Apples contain a high amount of Vitamin C which is an important requirement for guinea pigs as they do not have the ability to produce it for themselves.

Apples should not be a main meal for your pets. You should include a lot of fresh hay, veggies and Vitamin C pellets in their meals too.

Give them all parts of the fruit but avoid the seeds due to cyanide. The amount is not usually a lot but for small animals like guinea pigs a small amount is quite a lot and it could be dangerous.
