Can Guinea Pigs Eat Rice? (Risks, Facts & More)

In this article, we will talk about one healthy type of food – rice. In many diets nowadays, rice is listed as one of the healthiest foods that you can eat along with proteins. It is surely healthier than bread, and it is kind of a good carb. If this is healthy food for us, can it be healthy for the guinea pigs as well? Let’s check and see if our guinea pigs can consume rice!

Can guinea pigs eat rice? No, guinea pigs cannot eat rice because rice is a type of grain, and grains are not good for the guinea pigs. Another reason why guinea pigs cannot eat rice is that rice has to be cooked, and guinea pigs should never eat cooked foods. Naturally, they can consume only fruits, veggies, and some herbs – that’s why they are vegetarians and herbivores.

This staple food that is popular in Asian cuisine is only good for us and sadly not for the guinea pigs. There are plenty of other foods that you can give to the guinea pig without risking its health. You surely want to avoid the stomach cramps and bad digestion for the little furry friend. Always replace such foods with something fresh like veggies and fruits. It is simply not worth the trouble. If you are interested we have more information about rice as food for the guinea pigs in the following sections below.

Risks to Consider When Giving Rice to Guinea Pigs

  • No scurvy prevention – rice has no vitamin C. This is a bad thing because the guinea pigs need vitamin C to survive and to be healthy. They cannot produce this vitamin naturally, so they have to get it one way or another; through food or supplements. And, when they ingest this vitamin, they cannot store it. So, foods that lack vitamin C are not so beneficial for the guinea pigs.


  • Indigestion – in rice, there is not much fiber. In fact, the amount of fiber is even too low. Fibers are needed on a daily basis and in moderate amounts because they improve the digestion and bowel movements. With a lack of fiber, there is a risk of indigestion, or in severe cases, constipation.


  • Bad digestion – rice also has some sugar. Guinea pigs don’t digest sugars too well, and they get cramps or loose stool from excess sugar. This is because sugar makes them crampy and it isn’t received well by their digestive system. The sugar, and the lack of fibers in rice, both contribute to painful or problematic digestion.


  • Rapid weight gain – rice is full of carbs! The carbs are the one thing that always causes rapid weight gain for everyone. If carbs are eaten in excess, there will surely be a change on the weight scale! So, it is not a good idea to let the guinea pig consume a lot of carbs, especially not from cooked food like rice.

There is no exact serving size for rice because the guinea pigs cannot eat this food. The frequency of this for the cavies is: never.

  • Can My Guinea Pig Eat Rice Cakes?

No. if the guinea pigs cannot eat rice, they also can not eat rice cakes too. You might be tempted to give them the plain, tasteless rice cakes that do not have additional aromas, but this is still not good. Besides, rice cakes don’t have enough nutritional values for the guinea pigs.

  • Is It True That Boiled Rice Is Ok for Guinea Pigs That Have Diarrhea?

No, this is not true. Rice is too starchy for the cavies, and it is not the perfect cure for cases of diarrhea. The guinea pigs always need fresh water, pellets, veggies and fruits. Don’t forget that guinea pigs cannot consume cooked foods, no matter how you cook them.
