Green, yellow, orange and red — bell peppers come in a range of vibrant colors and are loaded with vitamins and minerals. They’re a nutritious snack for humans, but what about for cavies? Can guinea pigs eat bell peppers?

Yes. Guinea pigs can eat bell peppers of all colors. Green bell peppers are the best choice because they’re lower in sugar, but you can feed your guinea pig all types of bell peppers as long as they’re given in moderation.

What Are Bell Peppers?

While many people believe they’re vegetables, bell peppers are actually fruits from the nightshade family. Also known as sweet peppers and capsicums, they’re native to Central and South America.

High in vitamin C and low in calories, they make a nutritious snack for people and guinea pigs.

Why Do Bell Peppers Come in Different Colors?

Have you ever wondered whether there are any differences between the different-colored bell peppers on the shelves of your grocery store? The most common varieties are:

  • Green
  • Red
  • Yellow
  • Orange

You might be surprised to learn that these peppers all come from the same plant — green peppers are unripe fruits and red peppers are mature, while the yellow and orange varieties are partially ripened. Sweet peppers come in a variety of other colors, including purple and brown, but these are much less widely available.

There are also variations in taste and nutritional quality between the different colors. For example, red bell peppers are noticeably sweeter than green bell peppers, but they also contain much more vitamin C.

Are All Bell Peppers Safe for Guinea Pigs to Eat?

Yes. Bell peppers of all colors are safe for guinea pigs to eat. However, you’ll need to wash the pepper and remove the seeds before feeding a slice of pepper to your pet. You should also be careful not to let your guinea pig have too much of a good thing.

Nutrients in Bell Peppers

Sweet peppers provide a number of important nutrients that guinea pigs need. Some of the health benefits of bell peppers include:

  • High in vitamin C. Because guinea pigs can’t manufacture their own vitamin C, they must be fed a diet rich in vitamin C. Happily, bell peppers are an excellent source of this essential vitamin and can help prevent scurvy.
  • Low in calories. Thanks to their low-calorie content, bell peppers are a healthy snack and a great way to add essential nutrients to your pet’s diet.
  • Rich in antioxidants. Bell peppers contain many healthy antioxidants to promote a strong immune system, and are rich in vitamin A to reduce inflammation.
  • Source of fiber. Bell peppers are also a good source of fiber, which helps absorb sugar and also aids proper digestion.

The Best Bell Peppers for Guinea Pigs

Green peppers are generally considered to be the best option due to their lower sugar content. While they don’t contain as much vitamin C as other pepper varieties, they’re still a rich source of this important nutrient.

That said, it’s perfectly safe to feed your cavy yellow, orange and red bell peppers as well.

How Much Bell Pepper Should I Give My Guinea Pig?

One or two slices of bell pepper is the perfect serving size for your cavy. Some owners give their pets a daily serve of sweet pepper, but others opt to feed it 3-4 times a week if giving varieties that are higher in sugar.

It’s also important to introduce any new food to your pet’s diet slowly in case it causes an upset stomach. If your cavy has any sort of negative reaction to bell peppers, consult a veterinarian for advice.

Risks of Feeding Bell Peppers

There are a few risks you need to be aware of when feeding bell peppers to your guinea pig:

  • Seeds are a choking hazard. The small seeds inside bell peppers can be a choking hazard, so make sure to remove them before feeding a pepper to your cavy.
  • Overfeeding. Fresh hay and leafy vegetables should make up the majority of your cavy’s diet. Bell peppers can be included as part of a balanced diet, but they should never make up the bulk of what your pet eats. Feeding too much bell pepper to your guinea pig could result in an upset stomach.
  • High sugar content. Red bell peppers have a higher sugar content than green peppers. They’re still perfectly safe for your cavy to eat but should only ever be given in moderation.
  • Stem needs to be removed. Finally, make sure you remove the stem from the bell pepper as this is not safe for guinea pigs to eat.

Can Guinea Pigs Eat Spicy Peppers?

No. You should never give hot peppers or chili peppers to your guinea pig. Jalapenos and other hot peppers are too spicy for cavies to handle and could cause an upset stomach for your pet. Make sure to avoid them at all costs.


If you want to share a bell pepper with your furry friend, you can. Bell peppers of all colors are safe for guinea pigs to eat, but green peppers are the healthiest option. Just be sure to remove the seeds and the stem before serving any bell pepper to your cavy.
