The Ultimate Guinea Pig Food List

Here is the ultimate guinea pig food list.

If you just want to know if a certain food is safe for guinea pigs, you can use our Can Guinea Pigs Eat Tool.

You can sort the table by columns. Just click on the column header.

Because guinea pigs are herbivores, this list only contains fruits, vegetables, and plants. And I did not list every type of grass or weed, just common ones. If you there’s something you think should be added to the list, just let me know!

Name Edible? Notes
Avocados No The 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.
Alfalfa Yes Guinea 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 Sprouts Yes Alfalfa sprouts are safe for guinea pigs. They have a high amount of phosphorus, however, so I wouldn’t feed it more than a couple times a week.
Applesauce Maybe 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.
Apples Yes Guinea 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.
Apricots Yes Apricots are safe for guinea pigs. They can calso eat apricot tree leaves or chew on the branches.
Artichokes Yes There 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 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 times per week.
Arugula Yes Arugula is a good food for guinea pigs. It offers a pretty good amount of Vitamin C, as well.
Asian Pear Yes Guinea pigs can eat Asian pears. But like most fruit, because it contains sugar, limit it to a couple times a week.
Asparagus Yes Guinea pigs can eat asparagus. It is a nutrient-dense food that provides vitamins A and C.
Atemoya yes The atemoya is a hybrid between the cherimoya fruit and the sugar apple. They are not toxic but do contain a good bit of sugar, so limit their intake to once or twice a week.
Azalea No Eating azaleas can result in vomiting, diarrhea, or excessive drooling. Comsuming a lot could cause coma or death.
Bamboo Shoots Yes Guinea 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.
Bananas Yes Guinea pigs can eat bananas. Because of the sugar content, feed just a couple times per week. They can also eat the banana peels and the banana plant leaves.
Basil Yes Basil is safe for guinea pigs. It contains a good amount of Vitamin C, but it also contains high levels of phosphorous and calcium, so you should limit intake to a couple times per week in small amounts.
Bean sprouts Yes Bean sprouts are good for guinea pigs. They provide some Vitamin C as well.
Beets Yes Beets are safe for guinea pigs, but they have a high sugar content, so you should limit their consumption to a couple times per week at the most.

Blackberries Yes Guinea pigs can eat blackberries. They have a good amount of Vitamin C as well.
Blueberries Yes Blueberries are good for guinea pigs. They are nutrient-dense and provide Vitamin C as well. As with all fruits, because of the sugar content, limit intake to a couple times per week.
Bok Choy Yes Guinea pigs can eat bok choy. It has Vitamins A and C, but it also has a good amount of calcium, so limit it to once or twice a week.
Boston Lettuce Yes Guinea pigs can eat boston lettuce. It is more nutritious than iceberg lettuce.
Boysenberries Yes Boysenberries are good for guinea pigs. They offer Vitamin C as well as well as very little calcium.
Broccoflower Occasionally This cross between broccoli and cauliflower is a cruciferous vegetable. It is not toxic to guinea pigs, but it can cause gas and bloating and slow down the movement in the digestive system. If you do choose to feed it to your pet, do so in small amounts only and observe him closely for signs of illness including: diarrhea, bloating of the abdomen, disinterest in or refusing food, malaise, and lowered/absence of stool production.
Broccoli Occasionally Broccoli is a cruciferous vegetable. It is not toxic to guinea pigs, but it can cause gas and bloating and slow down the movement in the digestive system.

Cassava No Raw cassava contains cyanide, and guinea pigs don’t need cooked cassava. Guinea pigs should not eat cassava.
Cauliflower Occasionally Cauliflower is a cruciferous vegetable, and cruciferous vegetables can cause gas and bloating and slow down the movement in the digestive system. If you do choose to feed it to your pet, do so in small amounts only and observe him closely for signs of illness including: diarrhea, bloating of the abdomen, disinterest in or refusing food, malaise, and lowered/absence of stool production.
Celeriac Yes Celeriac is also called celery root. It is safe for guinea pigs.
Celery Yes Celery is safe for guinea pigs. It has a high water content, though, so could cause more frequent urination if fed in larger amounts. They can eat celery leaves, as well.

Some people say they are not safe because they belong to the allium family, but all research I’ve found states that they are safe.
Chrysanthemum No Chrysanthemums are poisonous to guinea pigs.
Cilantro Yes Cilantro is a healthy food for your guinea pig.
Coconut Occasionally Coconut is not toxic to guinea pigs, but it has a high amount of fat and phosphorous so if you feed it to your guinea pig, do so sparingly.
Collard Greens Occasionally Collard greens are high in calcium, Vitamin A, and oxalates which isn’t very good for guinea pigs. Also, collard greens are a cruciferous vegetable. 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.
Corn Yes Corn 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!
Cranberries Yes Cranberries 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.
Crocus No Crocuses 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 contain colchicine. The Autumn Crocus is highly toxic and can cause severe vomiting, gastrointestinal bleeding, liver and kidney damage, and respiratory failure.
Cucumber Yes Cucumbers 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 cucmber, as well. They are not nutritionally dense, however.
Cyclamen No This flowering plant is toxic to guinea pigs. It can cause vomiting or even death.
Daffodils No Daffodils 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.
Daikon Occasionally The daikon radish is high in oxalates and shouldn’t be a part of your guinea pig’s diet. The green leaves of the plant can be fed to them in a small amount once a week or even less often.
Dandelion Occasionally Dandelion greens are high in calcium, so their consumption should be limited to just once or twice a week. Dandelion flowers should only be given sparingly as an occasional treat.
Dates Yes Dates are safe for guinea pigs. They are high in sugar, however, so limit intake to once or twice a week at most. Be careful because some of the packaged dates you buy in the store are really coated with sugar. Stay away from those ones.
Dieffenbachia No Eating this houseplant can cause oral irritation, drooling, nausea, vomiting and difficulty swallowing.
Dill Yes Dill is safe for guinea pigs.
Edamame No Edamame are soybeans. Raw, unprocessed soybeans contain several substances that are very unhealthy for guinea pigs, including phytoestrogens, anti-enzymes, hemagglutinin, phytates and goitrogens. To read more about what raw soybeans contain see http://www.wereyouwondering.com/did-you-know-that-raw-soybeans-are-toxic/

Garbanzo Beans No Other 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.
Garlic Occasionally I 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 phosophorus and calcium content. For that reason, it should not be given often and only in very small amounts.
