Your guinea pig spotted the plums on the counter and wants one. They can eat them, but you need to be careful.
Plums provide 6.27 mg of vitamin C per fruit along with potassium for blood pressure regulation, but the pit is the real danger.
Can Guinea Pigs Eat Plums?
Guinea pigs can eat plums when they’re served in moderation. Plums are drupes, also called stone fruits, and they belong to the Rosaceae family alongside cherries and peaches.
The Japanese plum and European plum are the two most common varieties. Regardless of the type, all plums should be prepared the same way for your guinea pig: washed, pitted, and chopped into tiny pieces.
Quick Facts About Plums
- Plum sizes range from marble-sized to very large
- They’re grown on every continent except Antarctica
- Plums are low in protein, calories, and fat
- Their taste ranges from tart to sweet
- They come in different colors and shapes
Are Plums Good for Guinea Pigs?
Plums pack a solid nutritional punch for your piggy. They’re loaded with vitamins A, C, E, and K, plus antioxidants and flavonoids that reduce inflammation.

Health Benefits for Guinea Pigs
Plums offer several benefits when fed in the right amounts:
- Vitamin C helps with iron absorption and boosts the immune system
- Low calorie count keeps your guinea pig at a healthy weight
- Vitamin B6 supports a healthy nervous system by keeping nerve signal transmission smooth
- Anthocyanin and quercetin protect brain cells from breaking down
- Potassium helps control blood pressure and removes excess sodium through urine
- Sorbitol, a sugar alcohol in plums, acts as a natural laxative
Why Plums Can Be Bad for Guinea Pigs
Despite their benefits, plums come with real risks when overfed.
The Pit Is Dangerous
The plum pit contains amygdalin, which turns into cyanide during digestion. Swallowing a pit also creates a choking hazard.
If your guinea pig accidentally swallows one, get to a vet immediately for an X-ray and treatment.
Oxalates Cause Kidney Stones
Plums are high in oxalates, which bind to calcium and form rigid stones in the kidneys. This condition is called urolithiasis, and it’s painful.
Since guinea pigs are already prone to calcium stones, overfeeding plums makes the situation worse.
Calcium is still an essential nutrient your piggy needs, so don’t cut it out completely. Just be mindful of how much they’re getting from all food sources combined.
Digestive Upset
Guinea pigs didn’t evolve to digest large amounts of fruit. Too much plum can lead to nausea, diarrhea, and stomach discomfort.
Can Guinea Pigs Eat Prunes?
Don’t feed prunes to your guinea pig. Prunes are dried plums, and the drying process concentrates the sugar content dramatically.
One cup of pitted prunes contains roughly 66 grams of sugar and 12 grams of fiber. While that fiber gives prunes a low glycemic index for humans, the sugar load is way too high for a guinea pig’s digestive system.
It can cause diarrhea and stomach upset.
How to Prepare and Serve Plums
Follow these steps to serve plums to your guinea pig:
- Grab a fresh, firm plum and wash it well
- Cut off about one-eighth of the plum
- Chop it finely, keeping the skin on
- Serve it in a small bowl
- If your piggy doesn’t eat it within an hour, remove it
Keep the skin on because that’s where most of the antioxidants live. Only feed plums twice a week at most, no matter how much your piggy begs for more.
What to Do If Your Guinea Pig Ate a Plum Pit
If your guinea pig swallowed a plum pit, this is an emergency. The two main concerns are cyanide poisoning and physical obstruction.
Cyanide Poisoning
Plum pits contain amygdalin, which gets converted to cyanide in the small intestine. Even small amounts of cyanide are dangerous for a tiny guinea pig.
Physical Obstruction
A pit can get lodged in the digestive tract, causing extreme pain and potentially fatal blockages. Rush your guinea pig to a vet immediately for an X-ray and treatment.
What Should Be in Your Guinea Pig’s Daily Diet?
Guinea pigs have sensitive digestive systems, so their core diet should be simple. Unlimited timothy hay or another low-calcium hay forms the base, supplemented with a smaller amount of high-fiber, hay-based pellets.
They need vitamin C every day. Red and green bell peppers are excellent daily sources.
You can also offer safe vegetables like carrots, broccoli, kale, spinach, and tomatoes.
For fruit treats beyond plums, your piggy can enjoy apples, grapes, cantaloupe, strawberries, watermelon, and blueberries. Keep fruit as an occasional treat rather than a daily habit.
Foods to Avoid Completely
Guinea pigs are herbivores, but not all plants are safe. Avoid these entirely:
- Grass clippings (they ferment in the gut and cause bloating)
- Dock leaves (high in oxalic acid)
- Rhubarb (toxic and potentially fatal)
- Daisies, buttercups, and celandine (poisonous flowers common in grass)
- Plants that grow from bulbs (onions, garlic, daffodils, tulips, chives)
- Rabbit food (lacks the vitamin C guinea pigs need)
- Evergreen plants (boxwood, ivy, rhododendrons, laurel)
Final Thoughts
Guinea pigs can enjoy plums as a tasty treat when you follow a few simple rules. Always remove the pit, chop the fruit into tiny pieces, and limit servings to twice a week at most.
Plums offer real nutritional value with their vitamin C, potassium, and antioxidants. But the oxalates and sugar mean they should never become a daily food.
Stick with fresh, firm plums and skip the prunes entirely. Your piggy will get all the flavor and health benefits without the risks that come from overfeeding.
Frequently Asked Questions
The skin is actually the most nutritious part of the plum. It contains the highest concentration of antioxidants. Leave the skin on when you serve chopped plum pieces to your guinea pig, and always wash the fruit thoroughly first to remove any pesticide residue.
Twice a week is the maximum recommended frequency for plums. The high oxalate and sugar content makes daily feeding risky. Stick to about one-eighth of a plum per serving, chopped into small bite-sized pieces, to keep your piggy safe and healthy.
Dried plums (prunes) aren't safe for guinea pigs. The drying process concentrates the sugar content to roughly 66 grams per cup, which is far too much for your piggy's digestive system. Stick to fresh plums only and always serve them in small, chopped portions.
Watch for diarrhea, reduced appetite, lethargy, or signs of stomach discomfort like hunching or reluctance to move. If symptoms last longer than a day or your guinea pig stops eating and drinking entirely, visit your vet promptly for an evaluation and guidance.
