The Ultimate Guinea Pig Food List

If you’re looking for a complete and exhaustive list of Guinea Pig food, you’re in luck! We’ve compiled the top essentials below. Just keep in mind that some of these items may not be necessary for all guinea pigs, so it’s best to consult with your veterinarian before starting your pet on a specific diet.

Here Is The Ultimate Guinea Pig Food List.

Due to guinea pigs being herbivores, this list only contains fruits, vegetables, and plants. I did not list every type of grass or weed, just the most common ones. If there’s something you think should be added to the list, just let us know in the comment section.

I have also reviewed a few other ‘all in one food’ you can purchase from Amazon that your guinea pigs can eat.

NameEdible?Notes
Aa ChoyYesAa Choy (Lactuca sativa) is fine.
AvocadosNoThe skins of avocados seem to be toxic to guinea pigs. The inside of an avocado is not toxic and can be eaten, but avocados are high in fat. The high-fat content is not good for them and can slow down the digestive process.
AlfalfaYesGuinea pigs can eat alfalfa and often do as alfalfa hay. However, it is high in calcium which can lead to bladder stone formation, so give it sparingly. It is fine for young, nursing, or sick guinea pigs who need extra nutrition.
Alfalfa SproutsYesAlfalfa sprouts are safe for guinea pigs. They have a high amount of phosphorus, however, so I wouldn’t feed it more than a couple of times a week.
ApplesauceMaybe

Guinea pigs can eat applesauce, but the concern is the sugar content. Store-bought applesauce can contain 50% (or more) sugar. In that case, no – it’s not good for them. Check the sugar content to see if it’s something you want to give to your guinea pig. A better choice would be apples

ApplesYesGuinea pigs can eat apples. They can also eat the skin of the apple and the leaves of the apple tree, but the tree leaves are high in calcium, so limit their intake. They can also chew on the apple tree branches.

ApricotsYes

Apricots are safe for guinea pigs. They can also eat apricot tree leaves or chew on the branches.

ArtichokesYesThere are 3 kinds of artichokes – the globe artichoke (the one you normally think of), the Jerusalem artichoke, and the Chinese artichoke. Artichokes are safe for guinea pigs. They are a little high in phosphorous, so only feed them a couple of times a week at the most. Jerusalem artichokes are not toxic, but they contain high levels of sugar and phosphorus so they’re not an ideal food. Chinese artichokes are also high in sugar content and phosphorous, so they shouldn’t be given more than a couple of times per week.
ArugulaYesArugula is good food for guinea pigs. It offers a pretty good amount of Vitamin C, as well.

Asian PearYesGuinea pigs can eat Asian pears. But like most fruit, because it contains sugar, limit it to a couple of times a week.

AzaleaNoEating azaleas can result in vomiting, diarrhea, or excessive drooling. Consuming a lot could cause a coma or death.
Bamboo ShootsYesGuinea pigs can eat bamboo shoots. They are high in Vitamin C. Bamboo doesn’t have a high nutritional level, but it does offer lots of fiber. They can also eat bamboo leaves.

Like all cruciferous vegetables, they can cause gas and bloating. If you do choose to feed these vegetables to your pet, do so in small amounts only and observe closely for signs of illness including diarrhea, bloating of the abdomen, disinterest in or refusing food, malaise, and lowered or absence of stool production.
CornYesCorn is safe for guinea pigs. Corn itself has a high starch content, however, so feed sparingly. They can also eat corn silk, corn husks (watch out for pesticides), and even corn flakes, corn stalks, and corn hay. Be careful there are no pesticides, fungus, or bacteria on the stalks, hay, or husks!
CranberriesYesCranberries are safe for guinea pigs. You can also give them cranberry juice if it isn’t loaded with sugar, and if you dilute it a bit with water.
CrocusNoCrocuses are not safe for guinea pigs. There are two Crocus plants: one that blooms in the spring (Crocus species) and the other in the autumn Colchicum autumnale). The spring plants are more common and are part of the Iridaceae family. These ingestions can cause general gastrointestinal upset including vomiting and diarrhea. These should not be mistaken for Autumn Crocus, part of the Liliaceae family, which contains colchicine. The Autumn Crocus is highly toxic and can cause severe vomiting, gastrointestinal bleeding, liver and kidney damage, and respiratory failure.
CucumberYesCucumbers are safe for guinea pigs, and most guinea pigs love them. They have a high water content so too much can cause bloating or diarrhea. They can eat the outer skins of the cucumber, as well. They are not nutritionally dense, however.
CyclamenNoThis flowering plant is toxic to guinea pigs. It can cause vomiting or even death.
DaffodilsNoDaffodils contain lycorine, an alkaloid with strong emetic properties (something that triggers vomiting). Ingestion of the bulb, plant, or flower can cause severe vomiting, diarrhea, abdominal pain, and even possible cardiac arrhythmias or respiratory depression.

FigsYesFigs are healthy food for guinea pigs. Fresh digs have a high sugar content, so consumption should be limited to once or twice a week. Dried figs have less sugar content, however.
Garbanzo BeansNoOther than green beans, guinea pigs generally should not eat beans. They contain a toxin named phytohaemagglutinin that can cause vomiting, diarrhea, dehydration, and even death in guinea pigs.
GarlicOccasionallyI found much debate online about garlic for guinea pigs. There were many people saying it was not safe for guinea pigs but did not offer scientific proof. So I researched scientific studies and various scholarly books, and I believe garlic is safe for guinea pigs. \’Diseases of Domestic Guinea Pigs\’ by Virginia C. G. Richardson, MA, VetMB, MRCVS says it has several benefits for guinea pigs. Raw garlic has a high phosphorus and calcium content. For that reason, it should not be given often and only in very small amounts.

  1. Are oranges safe for guinea pigs? My family has oranges but the peels being thrown away seems like a waste to me. So I’m just curious if its safe. I’m a little hesitant about giving them new foods that I don’t know if safe or not.

  2. I grow a large amount of Hops for homebrewing…can Guinea Pigs eat hop leaves? I’m hesitant to try since I can’t seem to find any information on whether hops are toxic or not to them on-line. BTW, my Guinea Pigs LOVE fresh mushrooms!

  3. I LOVE this website. Whoever made this website did a VERY good job. Now when i’m not sure what my guinea pig can eat, I just come to this website.

  4. What about olive wood?
    I have this statue carved as a camel out of olive wood, but I don’t want it, so I thought maybe he guinea pigs wild like it for a Christmas chew toy?

    • Mushrooms offer very little nutritional content, so it’s not a good idea to give them mushrooms. But most types of mushrooms are not toxic to guinea pigs.

    • You can feed him sour grass in small amounts. Sour grass isn’t really a grass, it’s a type of sorrel, but it won’t hurt your huinea pig.

    • Yes, they can eat Bidens bipinnata (Spanish needles), but try to make it no more than 5% of their diet. See Miller, J.H., and K.V. Miller. 1999. Forest plants of the southeast and their wildlife uses. Southern Weed Science Society.
