What Can Guinea Pigs Eat? (Safe Foods List)

Have you ever wandered through a grocery store and wondered if a particular food was safe for your guinea pig to eat? This comprehensive list will tell you exactly what you can feed your guinea pig, as well as some important notes on precautions, quantities, and frequency that you can give each food.

Foods are separated into three categories; vegetables, fruit, and herbs.

Under these lists, foods are listed in alphabetical order so you can easily find what you’re looking for.

Keep in mind that some foods commonly recognized as vegetables, like bell peppers, cucumbers, zucchini, and tomatoes, are technically classified as a fruit, so you’ll find them under the fruit category in this list.

What Should Guinea Pigs Eat Daily?

While this is a list of fruits and vegetables that guinea pigs can eat, remember that the bulk of your guinea pig’s diet should be 80% grass hay. Timothy or orchard hay are both excellent choices. Guinea pigs should also have access to clean, fresh water at all times. Be sure to supplement their diet with 1/8 cup of high-quality pellets to ensure they get the minerals they need daily.

Lettuce and bell peppers are safe to feed daily, but be sure to mix in a variety of different veggies too!

Guinea pigs can eat up to 1 cup of vegetables and fruit per day. They can eat less as long as their Vitamin C needs are met.

Guinea pigs require 10-50mg of Vitamin C per day to prevent deficiencies that lead to a compromised immune system and diseases like scurvy. You can meet this need by regularly providing foods that are high in Vitamin C.

Calcium content is also crucial when choosing vegetables for your guinea pig. If you provide too many foods high in calcium, there is a chance your guinea pig could develop bladder stones.

It is safe to feed calcium-rich foods in reasonable quantities, but be sure to balance the diet with plenty of foods low in calcium.

Oxalates or oxalic acid should also be restricted in your guinea pig’s diet as much as possible. Too much of this can lead to stone development and many other health conditions. It’s best not to feed multiple veggies that are rich in oxalates at the same time.

While some of the following foods are safe to feed daily, it’s best to serve up a rotation of different veggies every day so your guinea pig gets a variety of nutrients from different sources. Check out our guinea pig food chart for an easy reference sheet on how often you can offer each food.

Of course, all guinea pigs will have different tastes, and you’ll discover their various likes and dislikes as you introduce new foods. You can check out this list of favorite foods that guinea pigs love to get you started.

Introducing New Foods to Your Guinea Pig

Always introduce new foods in small quantities!

If your guinea pig is trying any of the foods on this list for the first time, it’s crucial to introduce them into the diet gradually.

Some guinea pigs may have a bad reaction to a food, such as diarrhea, allergies, or stomach pains.

By giving new foods in small amounts, you can discover these potential problems before they become a serious health risk.

As long as your guinea pig acts normally after trying a new type of food, you can slowly increase the quantity each time.

Unsafe Foods For Guinea Pigs

Couldn’t find something on this list? There’s a chance it could be unsafe to feed your guinea pig. Check out our list of 45 Foods Your Guinea Pig Shouldn’t Eat for more information.

Many other foods, like avocado, are also unsafe for guinea pigs. Also, watch out for foods containing poisonous compounds, such as greenery from tomatoes or seeds from apple cores.
