Can Guinea Pigs Have Sweet Potatoes?

Yes – guinea pigs can eat sweet potatoes, but only in very small amounts and not too often. Just like other starchy root vegetables, sweet potatoes can cause digestive issues for your guinea pig if they are overeaten.

Are Sweet Potatoes Good For Guinea Pigs?

Let’s put it this way: If you decide to let your guinea pig have sweet potatoes, they’ll get some nutrients from this tasty treat. On the other hand, the portion size is small and your cavy won’t receive any major benefits.

Do Guinea Pigs Like Sweet Potatoes?

Yes! Most guinea pigs really like sweet potatoes.

Just as when other sweet veggies and fruits, cavies are eager to sink their teeth into a yummy slice of sweet potato.

How Much Sweet Potato Can A Guinea Pig Eat?


Your little friend isn’t going to like this answer much, because the appropriate serving size is almost ridiculously small. Here’s how much sweet potato to feed a guinea pig.

Age Amount
Baby guinea pig None
Adult guinea pig One 1” cube or four ½ inch cubes

We recommend reserving sweet potato as a special treat for your cavy simply because it contains higher levels of sugar and starch.

For the same reason, it’s very important to give your guinea pig a gradual introduction to sweet potato.

Start by offering your cavy a piece of sweet potato that measures about 1/2 inch square.

Monitor your pet carefully for the next 12 hours, watching for signs of discomfort or diarrhea.

If all goes well, then you can gradually increase the amount of sweet potato you give your guinea pig over the next few weeks until they are eating all four cubes.

How Often Can A Guinea Pig Eat Sweet Potato?

You can give guinea pig sweet potato once a week at most – and never on the same day as other starchy vegetables or sugary foods. Even though there’s less sugar in a sweet potato than there is in an apple, the combination of sugar and starch makes this vegetable a little difficult for cavies to digest.

There’s another reason to keep your guinea pig’s sweet potato intake low if you decide to offer this treat at all.

Ounce for ounce, sweet potatoes contain far more calories than the foods that make up a guinea pig’s natural diet. Overfeeding your pet can lead to obesity, which is both dangerous and uncomfortable for your guinea pig.

Even after your guinea pig is accustomed to eating sweet potato, be sure to keep an eye on them each time they have this treat. If they seem bloated, lethargic, or even a little under the weather, cut back on the sweet potatoes and foods other than hay and guinea pig food until they return to normal.

If your guinea pig has had an unpleasant reaction to sweet potato, it’s a sign that this and similar foods aren’t a good match for your pet’s digestive system.

The Correct Diet Is Important

Since sweet potatoes should make up a large portion of your guinea pig’s diet, what should you be feeding them instead?

Guinea pigs have a specialized digestive system. They must eat a diet that consists of high-fiber grasses and leafy green vegetables, with a few extra nibbles here and there.

The easiest way to satisfy this need is to provide your guinea pig with an unlimited amount of fresh hay.

In addition to hay, here’s what to feed your guinea pig every day:

  • A serving of vitamin C enriched guinea pig food. The package label is your guide to feeding the correct amount based on your guinea pig’s size and life stage.
  • About 1 cup of fresh veggies, mostly leafy greens.
  • Tiny amounts of fruit for special treats – always check for information about the correct serving size.
  • An unlimited supply of fresh, clean water. Remember to rinse and refill your guinea pigs drinking bottle at least once a day.

Last but not least, remember to keep your guinea pig well supplied with chew toys. Not only is constant nibbling a natural behavior that keeps your guinea pig mentally healthy, it’s essential for wearing down your guinea pig’s teeth, which never stop growing.

Without items such as hay cubes, unbleached loofah, and untreated softwood sticks, your guinea pig’s teeth are at risk of becoming overgrown. This condition can be painful and it can lead to an infection that requires medical intervention.

What Are Other Healthy Alternatives To Sweet Potato In A Guinea Pig’s Diet?

Guinea pigs may not be able to eat an unlimited amount of sweet potatoes, but there are plenty of other healthy treats to try:

  • cilantro
  • parsley
  • basil
  • mint
  • Swiss chard
  • asparagus
  • spinach
  • cabbage
  • Green beans
  • cucumber
  • zucchini
  • summer squash
  • pumpkin
  • Winter squash
  • bok choy
  • bell pepper
  • carrots
  • carrot tops
  • apple
  • pear
  • dill
  • blueberry
  • Brussel sprouts

Whether you decide to give your guinea pig sweet potatoes or stick to treats with less sugar and starch, they’ll appreciate the fresh foods you provide!

Just as you did when searching for information about sweet potatoes for guinea pigs, spend a few minutes researching each new food you’re considering for your pet.

It’s the best way to avoid foods that are toxic to guinea pigs, plus it’s a great way to ensure that you are offering the right amount of foods that are safe for your cavy.
