Do guinea pigs like bell peppers?

Believe it or not, guinea pigs love bell peppers! The mildly sweet flavor is simply irresistible.  Also, guinea pigs love bell peppers because of their crunchy and juicy texture. Here’s another fun fact. Did you know that bell peppers are 92% water, and the rest are carbs, fat, and protein? 

Also, a gentle reminder, guinea pigs should stay away from jalapeno peppers. Hot chili peppers are too spicy and would result in stomach upset. 

Health benefits of bell peppers for guinea pigs

In general, sweet peppers have high water content, low sugar content, and are rich in vitamins, minerals, and antioxidants. But if your guinea pig has special dietary needs, here are a few tips to know which one is best for your pet. 

If your guinea pig is overweight and diabetic, avoid orange and red bell peppers because they have high sugar content.

If your guinea pig has vitamin C deficiency, you can feed him with green or yellow bell pepper. Yellow bell peppers have almost zero sugar content but are rich in vitamin C.

If your guinea pig is constipated, that means he doesn’t have enough fiber in his system. The green bell pepper is the solution for this. 

Lastly, if your guinea pig is perfectly healthy, any color of bell pepper will do, as long it’s not the hot chili ones.

Serving size and frequency of bell peppers for guinea pigs

  • You likely won’t be surprised by my answer. Since guinea pigs need a lot of variety in their diet, they shouldn’t eat too much of a single vegetable and that includes bell pepper.
  • The recommended amount is one to two slices (about 1-3 tablespoons) 3-4 times a week for an adult guinea pig, or 1/2 tablespoon per week for small guinea pigs. 
  • It is also important to make sure that the bell pepper is washed thoroughly before giving them to your guinea pig. This will help remove any dirt, harmful bacteria, or contaminants that could make your guinea pig sick.

You should stick to a diet that closely resembles what they would naturally eat. According to the authors of “biology of the Guinea Pig” your guinea pig’s diet should include:

  • 90% of your guinea pig’s diet should be made up of grass hay such as timothy hay or alfalfa hay and quality guinea pig pellets.
  • 1/2 cup of fresh leafy vegetables as part of their daily diet. Guinea pig owners should try to buy dark green leafy greens which are naturally high in Vitamin C and dietary fiber.
  • 1/4 cup of fresh fruits 2-3 times per week as a treat cut into small pieces. Fruit generally has a high sugar content and should not be given every day.
  • Fresh water should be available at all times. Preferably given from a pet-specific sipper bottle.
  • No human processed food of any kind.
  • It’s always a good idea to introduce new foods slowly as they have sensitive digestive systems.
