Clean Label Project The Purity Crisis in Commercial Pet Food
Why Fresh, Single-Protein Diets Are the Future of Feline Health
For years, cat owners have trusted commercial pet food labels implicitly. However, a landmark study conducted by the Clean Label Project has highlighted a large number of problems with the commercial pet food industry, revealing widespread contamination. The non-profit organisation chemically tested 100 cat food products across 62 popular brands, screening for over 122 environmental contaminants, heavy metals, and industrial toxins. The findings are worrying at best, dangerous at worst.
The Clean Label Project study tested 100 cat food products from 62 cat food brands (US brands) and revealed that heavy metals are shockingly pervasive in standard commercial cat foods.
-
99% of products tested positive for lead
-
96% contained cadmium
-
94% contained arsenic
The research highlighted two primary culprits behind these elevated toxicity levels:
-
Kibble: Traditional dry kibble exhibited roughly three times the lead levels on a per-calorie basis compared to wet or fresh alternatives. This is due to the extreme, high-heat industrial processing (extrusion) and the reliance on low-grade agricultural fillers that absorb environmental contaminants from the soil. How it’s made
-
Seafood: Fish and seafood-based formulas contained up to 28 times higher amounts of mercury than poultry or beef options, driven by bioaccumulation in marine life.
For a species as small as a domestic cat, chronic exposure to even trace amounts of these heavy metals can lead to long-term kidney strain, digestive disorders, and neurological issues over time.
How CatChi Eliminates this Risk
CatChi has emerged as a gold standard for transparency of ingredients and feline nutrition. CatChi’s ingredient approach and gentle cooking method removes the risk that the Clean-Label project identifies.
1. Single-Protein Recipes & Radical Transparency
The most effective way to eliminate the high mercury risks associated with seafood is to remove seafood from the equation entirely. CatChi’s product range is completely fish-free, focusing instead on species-appropriate, single-protein recipes like chicken, beef, lamb, and pork (recipes). Because each meal is built around a single animal source, there is zero risk of cross-contamination or hidden marine byproducts, making it an exceptionally pure choice for health-conscious owners and sensitive cats alike.
2. Human-Grade Ingredients
Commercial kibbles often rely on "feed-grade" or “pet-grade” ingredients, which permit higher thresholds of environmental contaminants, pesticides like glyphosate, and chemical additives. CatChi completely rejects feed-grade infrastructure. Their recipes contain over 95% premium, human-grade muscle meat and organs, sourced from trusted Australian suppliers.
3. Gentle Cooking Preserves Purity and Nutrition
The high-heat, high-pressure extrusion process used to manufacture dry kibble chemically alters the ingredients and can exacerbate the concentration of heavy metals. In contrast, CatChi utilises a gentle, low-temperature cooking method, 72 degrees for 2 minutes. This process eliminates harmful pathogens while preserving the integrity of the natural vitamins, minerals, and moisture essential for our cats.
4. Safe Storage and Clean Packaging
The commitment to purity extends to how the food is stored and delivered. Rather than relying on chemical preservatives, artificial stabilisers, or shelf-stable cans lined with potentially harmful coatings, CatChi relies on the oldest natural preservative: cold temperatures.
Meals are portioned into food-safe packaging and immediately snap-frozen to lock in freshness. Delivered via a temperature-controlled cold chain directly to doors across NSW, Victoria, Queensland and the ACT, the food transitions from the freezer to the fridge with zero chemical intervention.
