1. Hay (80% of their diet):
* Timothy hay: The best choice for adult guinea pigs. It's high in fiber, low in calcium, and helps keep their digestive system healthy.
* Other hays: You can offer a small amount of oat hay or orchard grass, but Timothy hay should be the primary source.
2. Pellets (5-10% of their diet):
* High-quality pellets: Look for pellets formulated specifically for guinea pigs with at least 16% fiber and low calcium. Avoid pellets with added sugars, artificial colors, or flavors.
* Amount: Offer a small amount of pellets daily, adjusted to your guinea pig's individual needs.
3. Fresh vegetables (10-15% of their diet):
* Variety: Offer a wide range of fresh vegetables, including leafy greens (kale, spinach, romaine lettuce), bell peppers, carrots, broccoli, and zucchini.
* Moderation: Offer a variety of vegetables daily in limited quantities, as excessive amounts of certain vegetables can lead to digestive issues.
* Avoid: Avocado, onions, garlic, rhubarb, and other toxic vegetables.
4. Fresh fruits (5% of their diet):
* Moderation: Offer a small amount of fruits like strawberries, blueberries, bananas, or melon as a treat a couple of times a week.
* Avoid: Citrus fruits, grapes, and other fruits that are high in sugar.
5. Water:
* Fresh and clean: Always provide fresh water in a ceramic or stainless steel water bottle or a bowl.
Additional Tips:
* Introduce new foods gradually: To avoid digestive upsets, introduce new foods slowly, one at a time, and observe your guinea pig for any adverse reactions.
* Free-choice hay: Provide unlimited access to hay throughout the day.
* Grazing time: Allow your guinea pig to graze on fresh grass in a safe outdoor area.
* Vet checkups: Regular vet checkups are essential to ensure your guinea pig remains healthy.
Remember that every guinea pig is different and may have individual dietary needs. Consult with your veterinarian for personalized recommendations and guidance on your guinea pig's diet.
