Sweet potatoes are often considered a superfood in the human diet, and they are praised for their health benefits and abundance of vitamins and minerals. Because they’re so healthy for us, we often wonder if they are safe for our guinea pigs. The short answer is, no, sweet potato is not considered safe to feed your guinea pig. We’ll discuss everything you need to know about the health benefits and potential risks of giving sweet potatoes to your guinea pig below.

divider-guineapig Why Should I Not Feed My Guinea Pig Sweet Potato?

The nutrients found in sweet potatoes are good for humans, but unfortunately, sweet potatoes are likely toxic for guinea pigs.

Sweet potatoes can be infected with the common mold, Fusarium solani. This mold is found all over the world. The result of this infection is the production of a chemical known as 4-ipomeanol, and exposure to this chemical is solely by ingestion. It is responsible for the poisoning of cattle fed moldy sweet potatoes, and the result of this poisoning is often fatal respiratory distress. Likewise, 4-Ipomeanol is a highly specific lung toxin in rats, guinea pigs, and rabbits. Therefore, it is best to not offer your pet sweet potatoes.

Are There Other Risks Involved?

No food is perfect, and there are some additional drawbacks to giving your guinea pig sweet potato, even if it was determined that the potato was mold-free.

The first concern, especially given the name of the food itself, is the carbohydrate content. Sweet potato isn’t nearly as high in sugar content as most fruits, but the high amounts of carbohydrates and starch in sweet potatoes means they should be given to your pig as an occasional treat and not as a part of their regular diet.

Another concern with feeding your guinea pig sweet potato is the number of oxalates found in the vegetable. Oxalates are naturally found in many foods, and oxalates in high concentration can cause kidney problems and other complications in guinea pigs.

Sweet potatoes aren’t that healthy for your guinea pig, even if they are mold-free.

Anything Else to Consider?

Yes! There’s a very important distinction to be made between sweet potatoes and other kinds of potatoes like russet, white, and red potatoes. While sweet potatoes are dangerous for your guinea pig in their own way, other types of potatoes may also contain toxins and can be detrimental to your pet’s health.



While humans love sweet potato for its vitamin and mineral content, alongside its unique flavor, the tuber is considered toxic for guinea pigs and shouldn’t be offered to them. The presence of a ubiquitous mold renders them too risky. Even if they were mold-free, they have other health issues associated with them and aren’t compatible with a guinea pig’s diet. Caution is advised against other types of potatoes as well. It is best to seek safer vegetable options instead.

Remember that if you’re ever in doubt about your pet’s nutritional needs and safety, you should reach out to your exotic veterinarian for more information.
