Can guinea pigs eat rice?

No, guinea pigs cannot eat rice. This may come as a surprise to most since guinea pigs can eat almost anything, however, rice is not included in that list. Guinea pigs are herbivores and will eat anything as long as it is a vegetable, fruit, or a leafy green substance.

Rice is a grain, which is considered a staple in the Asian and Latin regions. Guinea pigs being herbivores cannot eat rice in raw form as it is hard to chew and not favorable for them.

Another question arises, can they eat cooked rice then? The answer to this is also, no. Guinea pigs cannot eat anything which is cooked, including rice. So, giving rice to your guinea pig, either in grain form or cooked or simply in any other way is harmful. It does no good to them and they most likely would not eat it on their own.

Cooked rice holds too much water content as a grain for guinea pigs for it to be added to their deaths. While, in raw forms, it is so hard to chew and can cause damage to their dental cavities. These animals are complete vegetarians and herbivores and should not be given grains as any part of their diet.

If guinea pigs could eat rice they would have health benefits not limited to the better cardiovascular and immune system, improved nervous system, and more energy as it is highly nutritious.
