As a cozy mom who loves small pets, you understand that a healthy guinea pig starts with the right food. Guinea pigs have unique dietary needs, including the essential vitamin C they cannot produce themselves, making their food choices crucial to their happiness and health.
In small homes and apartments, feeding routines need to be simple, nutritious, and mess-free. This post will guide you through the best guinea pig foods—from fresh veggies and hay to trusted pellet brands—so you can provide the very best for your little companion.
1. Timothy Hay: The Foundation of a Healthy Diet
Hay is the cornerstone of any guinea pig’s diet. Timothy hay is especially recommended because it provides the necessary fiber for digestive health and helps keep their teeth worn down naturally.
Why Timothy hay is best:
- High fiber content supports gut health and prevents obesity
- Promotes dental health by naturally grinding teeth
- Low in calcium reduces risk of bladder stones
- Encourages natural foraging behavior which keeps piggies active and happy
Popular brand:
- Oxbow Timothy Hay – Consistently fresh and high quality, trusted by small pet owners worldwide.
2. Fresh Vegetables: Variety & Vitamin C Boost
Fresh veggies are essential for vitamin C and variety. Leafy greens, bell peppers, and carrots are favorites. Avoid iceberg lettuce as it offers little nutrition.
Why fresh veggies matter:
- Provide vitamin C needed daily to prevent scurvy
- Hydrating and nutrient-rich support overall health
- Encourage natural chewing and exploration
Top picks:
- Bell peppers (red, yellow, orange) — rich in vitamin C
- Kale and Romaine lettuce — packed with nutrients
- Carrots and cucumbers — good treats in moderation
Cozy mom tip:
Wash and chop veggies fresh daily, offering small portions to avoid waste and maintain cleanliness.
3. High-Quality Pellets: Balanced Nutrition Made Easy
Pellets formulated for guinea pigs provide a consistent source of vitamins and minerals, especially vitamin C.
Why premium pellets matter:
- Fortified with vitamin C essential for piggy health
- Balanced nutrients to complement hay and veggies
- Easy to measure and store for busy families
- Help reduce selective feeding which can cause nutritional gaps
Recommended brands:
- Oxbow Essentials Adult Guinea Pig Food — no fillers, high fiber, trusted by vets
- Kaytee Forti-Diet Pro Health Guinea Pig Food — affordable and vitamin-enriched
4. Vitamin C Supplements: Extra Support When Needed
While fresh veggies and pellets provide vitamin C, sometimes your guinea pig needs extra, especially if they’re picky eaters or ill.
Why supplements are helpful:
- Prevent vitamin C deficiency-related illnesses like scurvy
- Easy to add to water or food
- Support immune health and vitality
Cozy mom favorite:
- Oxbow Natural Science Vitamin C Supplement — natural, easy-to-use drops or powder
5. Treats: Healthy & Sparing
Treats should be given sparingly and must be healthy options like small pieces of fruit or specially made guinea pig treats.
Why treat wisely:
- Prevent obesity and digestive upset
- Encourage positive interaction without overfeeding
- Maintain natural dietary balance
Safe treats:
- Small pieces of apple, strawberry, or blueberry
- Dried herbs or hay-based treats like Oxbow Simple Rewards
6. Foods to Avoid

Certain foods are toxic or unhealthy for guinea pigs and should never be given.
Avoid:
- Chocolate, caffeine, or sugary foods
- Onions, garlic, and potatoes
- Iceberg lettuce (low nutrition)
- Seeds or nuts (choking hazard)
7. Feeding Routine Tips for Cozy Homes
- Offer unlimited fresh hay daily
- Provide a measured portion of pellets once or twice a day
- Rotate fresh veggies daily, washing and chopping before feeding
- Clean food bowls daily to prevent mold and bacteria
- Monitor food intake and adjust portions as needed
