Guinea pigs are delightful pets that need a carefully balanced diet to stay healthy and active. They have specific nutritional needs, including vitamin C, which they cannot produce on their own. Here’s what they can eat, what to avoid, and how to create a balanced daily menu.
What Guinea Pigs Can Eat 
Hay
Hay is the cornerstone of a guinea pig’s diet and should be available 24/7. It supports digestive health and naturally wears down their continuously growing teeth. Timothy hay, alfalfa (for young guinea pigs), and oat hay are top choices. Chewing hay also provides mental stimulation as guinea pigs explore and nibble.
Fresh Vegetables
Daily servings of fresh vegetables are essential. Bell peppers, broccoli, carrots, spinach, and leafy greens are rich in vitamins and minerals. Bell peppers are especially important as a vitamin C source and should be included regularly.
Guinea Pig Pellets
Specially formulated pellets supplement a guinea pig’s diet. Many are fortified with vitamin C, but choose options free of artificial colors and additives. Pellets should complement hay and fresh vegetables rather than replace them.
Fruit as a Treat
Fruits like apples, strawberries, and pears can be given occasionally as treats. Due to high sugar content, limit fruit to small portions once or twice a week.
Foods to Avoid
High-Sugar and Fatty Foods
Sweets, chocolate, and processed foods can cause obesity and digestive problems. Avoid these entirely.
Certain Vegetables
Potatoes, onions, garlic, and legumes can lead to bloating and digestive issues. These are not suitable for guinea pigs.
Acidic Fruits
Citrus fruits such as oranges, lemons, and grapefruits may irritate the digestive system and should be given sparingly, if at all.
Grains and Seeds
Although they may seem appealing, grains and seeds are not a natural part of a guinea pig’s diet and can pose a choking hazard.
Creating a Balanced Menu
A healthy diet focuses on hay as the main component, with fresh vegetables and a moderate amount of pellets. Example daily menu:
- Breakfast: A handful of fresh Timothy hay and a few slices of bell pepper
- Lunch: A portion of pellets with some broccoli or carrot
- Dinner: More hay and a small piece of apple as a treat
Fresh water should always be available and the water bottle checked regularly for cleanliness.
Tips for Long-Term Health
Proper nutrition is the foundation of a guinea pig’s well-being. Monitor their behavior and appetite regularly. If you notice decreased appetite, lethargy, or unusual symptoms, consult a veterinarian promptly. With the right care and a balanced diet, guinea pigs can live long, happy lives, bringing joy to their owners.
