Step‑by‑Step Instructions

  1. Combine dry grains: In a large mixing bowl, combine rolled oats and barley flakes. Stir well.
  2. Add flaxseed meal: Sprinkle flaxseed meal over the grains and mix thoroughly to distribute evenly.
  3. Incorporate dried herbs: Crush chamomile, dandelion, and parsley slightly between your fingers, then stir into the mixture.
  4. Optional seeds: If using sunflower seeds, crush them and add no more than 1 teaspoon per 2 cups of mix. (Sunflower seeds are high in fat – use sparingly.)
  5. Store properly: Transfer the mix to an airtight glass jar or container. Keep in a cool, dark cupboard or refrigerator.
  6. Serve daily: Offer 1 tablespoon of dry mix per guinea pig per day, alongside unlimited hay and a generous portion of fresh vegetables (especially bell pepper for Vitamin C).

Pro tip: This mix is a supplement, not a complete diet. Hay and fresh veggies must always be the main foods.

Why These Ingredients Work

Ingredient Benefits

  • Rolled oats: Gentle, digestible fiber and energy.
  • Barley flakes: Adds texture and variety; supports gut health.
  • Flaxseed meal: Rich in omega‑3s for skin and coat health.

How to Incorporate the DIY Mix

  • Portion: 1 tablespoon per adult guinea pig, once daily (morning or evening).
  • With fresh food: Place the dry mix in a separate small bowl or sprinkle over vegetables.

Frequently Asked Questions

Can this DIY mix replace pellets entirely?

This mix can be part of a pellet‑free diet, but you must provide a reliable daily source of Vitamin C (bell pepper, cilantro) and ensure variety in vegetables. Some owners still include a small amount of high‑quality pellets for guaranteed vitamin balance.

How much of this mix should I feed per day?

1 tablespoon per adult guinea pig, once daily. Reduce to ½ tablespoon if your guinea pig is overweight or sedentary.

Is flaxseed safe for guinea pigs?

Yes, ground flaxseed (flaxseed meal) is safe in small amounts. It provides beneficial omega‑3 fatty acids. Do not feed whole flaxseeds as they are hard to digest.

Can I add dried fruit to the mix?

No. Dried fruit is concentrated in sugar and can lead to obesity and diabetes. Stick to fresh fruit as an occasional treat (once a week).

How long does the mix last in the fridge?

Refrigerated in an airtight container, the mix stays fresh for up to 8 weeks. For longer storage, freeze in a sealed bag for up to 4 months.
