What do guinea pigs eat?




Guinea pigs, also known as cavies, are adorable small mammals that make great pets. If you're considering getting a guinea pig or already have one, it's crucial to understand their dietary needs. Providing a well-balanced diet is essential for their overall health and well-being. In this article, we will explore what guinea pigs eat and how to ensure they receive the proper nutrition.

Natural Diet of Guinea Pigs

In the wild, guinea pigs are herbivores, meaning they primarily eat plants. Their natural diet consists of a variety of grasses, herbs, flowers, and vegetables. Guinea pigs have a unique digestive system that requires a high-fiber diet to maintain optimal gut health.

Hay: The Foundation of Their Diet

Hay is the most important component of a guinea pig's diet. It provides essential fiber, aids in digestion, and helps wear down their constantly growing teeth. Timothy hay is the most commonly recommended type of hay for guinea pigs, although orchard grass, meadow hay, and oat hay can also be suitable alternatives.

Vegetables: A Crucial Source of Vitamins

Fresh vegetables are an essential part of a guinea pig's diet, as they provide vital nutrients and vitamins. Dark leafy greens such as kale, romaine lettuce, spinach, and cilantro are excellent choices. Other suitable options include bell peppers, carrots, cucumbers, and zucchini. It's important to introduce new vegetables gradually to prevent digestive upset.

Fruits: Occasional Treats

While fruits are delicious and nutritious, they should be considered treats rather than a staple part of a guinea pig's diet. Fruits are high in natural sugars and should be fed sparingly to avoid weight gain and digestive issues. Safe fruits for guinea pigs include small pieces of apple, pear, melon, and berries.

Pellets: A Balanced Nutritional Supplement

Commercial guinea pig pellets can be a convenient way to provide your furry friend with a balanced diet. Look for high-quality pellets that are specifically formulated for guinea pigs. Avoid mixes containing nuts, seeds, or dried fruits, as these can be high in fat and sugar. Pellets should make up a small portion of their overall diet.

Water: Essential for Hydration

Fresh, clean water should be available to your guinea pig at all times. Use a water bottle with a sipper tube to ensure they have a constant supply of water. Regularly check the water bottle to ensure it is working correctly and refill it daily.

Avoid Harmful Foods

As a responsible pet owner, it's crucial to know which foods are harmful to guinea pigs. Avoid feeding them foods such as chocolate, caffeine, onions, garlic, potatoes, and rhubarb, as these can be toxic and cause serious health issues.


Understanding what guinea pigs eat is vital for their overall health and happiness. A diet rich in hay, fresh vegetables, occasional fruits, and balanced pellets will ensure they receive the necessary nutrients. Remember to always provide fresh water and avoid harmful foods. By offering a well-rounded diet, you can contribute to your guinea pig's longevity and well-being.
