What do guinea pigs and rats eat? - in detail
Guinea pigs require a diet high in fiber and vitamin C. The core component is unlimited access to fresh hay—timothy, orchard, or meadow varieties—providing essential roughage for digestive health. Fresh vegetables should be offered daily, focusing on leafy greens such as kale, romaine lettuce, and cilantro, alongside bell peppers, carrots, and small portions of fruit (e.g., apple slices, berries) for occasional enrichment. Commercially formulated pellets fortified with vitamin C supplement the diet; a daily portion of 1–2 tablespoons per 500 g body weight is appropriate. Water must be available at all times in a clean bottle or bowl. Toxic items to avoid include iceberg lettuce, onions, garlic, avocado, and any processed human foods.
Rats thrive on a balanced mix of protein, carbohydrates, and fats. A high‑quality rodent pellet should constitute the staple, delivering 14–16 % protein and essential nutrients. Fresh produce can be added several times a week: broccoli, peas, spinach, and small pieces of apple or banana. Protein sources such as boiled egg, cooked chicken, or mealworms may be offered sparingly (no more than a few grams per day). Rats also need continuous access to fresh water. Foods that are hazardous include chocolate, caffeine, raw potatoes, citrus peels, and any moldy or spoiled items.
Both species benefit from occasional mineral or vitamin supplements when dietary sources are insufficient. Monitoring body condition and adjusting portions based on activity level and age helps maintain optimal health.
