Guinea Pig Food

Niblee Guinea Pig Food. Small-Batch Premium Feed Built for Pet Guinea Pigs.

Built on 84.5% forage and fiber with a unique 4-hay blend of Timothy, Alfalfa, Orchard Grass, and Mountain Teff. Every batch third-party lab tested at Niblee Lab.

The Problem With Most Guinea Pig Feed

Most commercial guinea pig feed was never designed specifically for guinea pigs. It started as a rabbit formula or a generic herbivore base, then got slapped with a guinea pig label and a splash of added Vitamin C.

Guinea pigs are not small rabbits. Their Vitamin C dependency is unique. Their dental wear patterns are specific. Their gut biology requires fiber structure that generic herbivore formulas were never designed to deliver.

And then there is the Vitamin C problem. Most commercial guinea pig food sits in a warehouse for months before it ever reaches your pet. Vitamin C degrades the whole time. By the time your guinea pig eats it, the Vitamin C is a fraction of what the label claims.

These formulas have not been meaningfully updated in decades. The guinea pig world has learned more about fiber structure, Vitamin C stability, and species-specific nutrition in the last 15 years than in the previous 50. The old formulas did not keep up.

Niblee Is Different

Niblee Guinea Pig Food was formulated specifically for guinea pigs. Vitamin C sensitivity. Dental wear requirements. Gut biology. Species-specific thinking from the ground up.

Every ingredient in this bag earned its place because guinea pigs actually benefit from it.

Cold-milled by hand in small batches at the Niblee ranch in Grass Valley, California.

Fiber Structure, Not Just Fiber Percentage

Every bag is 84.5% Forage and Fiber Structure, built upon four sun-cured hays: Timothy Hay, Alfalfa Hay, Orchard Grass Hay, and Mountain Teff Hay.

We grind on larger screens to keep the hay strands intact, so the fiber actually functions in your guinea pig's gut, instead of passing through as dust. Fiber structure, not just fiber percentage, is what supports healthy gut motility, proper cecum fermentation, and correct dental wear.

Vitamin C, Delivered Fresh

Guinea pigs cannot make their own Vitamin C. They need it in every meal, every day, for life.

Most commercial guinea pig food sits in a warehouse for months before it ever reaches your pet. Vitamin C degrades the whole time. By the time your guinea pig eats it, the Vitamin C is a fraction of what the label claims.

Niblee is never warehoused. We mill, we ship, you feed. Vitamin C is actually there when it arrives.

We recommend using your Niblee Guinea Pig Food within 90 days of opening for optimal Vitamin C potency, paired with daily fresh vegetables and unlimited hay for complete nutrition.

Omega-3 and Omega-6 Balance for Skin and Coat

Every Niblee Guinea Pig formula includes stabilized flaxseed and stabilized rice bran, engineered to deliver a balanced ratio of omega-3 and omega-6 fatty acids. Guinea pigs thrive on properly balanced fats, and this balance shows up in coat condition, skin health, and overall vitality over time.

Triple-Stack Microbial Support

Niblee Guinea Pig Food includes a triple-stack microbial approach: prebiotics, probiotics, and postbiotics. Prebiotics feed the beneficial bacteria. Probiotics introduce live cultures. Postbiotics provide the beneficial metabolites from fermentation. Together they support the cecum fermentation guinea pigs rely on for nutrient absorption.

Spirulina for Immune Support

Niblee includes spirulina, a blue-green algae with peer-reviewed research supporting its role in immune function and micronutrient density. Spirulina is rare in US small animal feed and one of several reasons Niblee costs more than mass-market alternatives.

Clean Label. Every Ingredient Listed With Its Purpose.

No soy. No corn. No wheat. No molasses. No wheat middlings. No soy hulls. No screenings. No cheap bulk-filler ingredients. Ever.

Every ingredient is listed with its purpose on our full Ingredient-by-Ingredient page. Nothing is hidden. Nothing is filler. Every ingredient earns its place.

Transparency From Mill to Bowl

Every single batch is third-party lab tested. The results are published with lot-searchable lookup at Niblee Lab. No other small animal feed company does this.

Why Niblee Costs More

Niblee Guinea Pig Food is $25 per 4 pound bag. We cost more because we cost more to make.

• Formulated specifically for guinea pigs, not adapted from a rabbit or generic base. Most guinea pig feeds are rebranded rabbit formulas with added Vitamin C. Niblee is not. Every ingredient is there because guinea pigs benefit from it.
• Four species-appropriate long-stem hays, not hay meals. Mass-market feeds use ground hay meal or a single generic hay base. We use Timothy, Alfalfa, Orchard Grass, and Mountain Teff in their intact long-stem form.
• Larger-screen grinding to preserve fiber structure. Slower process, lower yield per batch, but the fiber actually functions in your guinea pig's gut.
• Third-party lab testing on every batch. Every bag. Every batch. Every result published at Niblee Lab. No other small animal feed company does this.
• Non-commercialized, small-batch cold-milling at the Niblee ranch. Not industrial production. Not contract-manufactured.
• No warehouse, no middleman, no corner-cutting. Your bag ships within 1-2 weeks of milling, so Vitamin C is actually there when it arrives.
• No filler ingredients. Ever. No soy. No corn. No wheat. No molasses. No wheat middlings. No soy hulls. No screenings. No cheap bulk-filler ingredients that pad the weight without feeding the animal. Every single ingredient has a nutritional purpose and earns its place in the formula.

Niblee is built for people like you. People who care about what goes in the bowl.
