What’s actually in Wellness CORE Cat?
We analyzed Wellness CORE Grain-Free Original cat food. The ingredient list opens with a protein quartet that’s almost unprecedented in dry cat food: deboned turkey, deboned chicken, turkey meal, and chicken meal occupy the first four positions. That’s two fresh whole meats followed by two concentrated meat meals before any plant ingredient appears. Herring meal at position seven adds a third animal protein species.
Peas and chicken fat follow the protein base. The formula includes salmon oil and flaxseed for omega-3 fatty acids, cranberries and dried kelp for antioxidants, chicory root for prebiotic fiber, and three distinct probiotic strains (Enterococcus faecium, Bacillus licheniformis, Bacillus subtilis). Chelated minerals (zinc, iron, copper, manganese proteinates) are used throughout. Shop on Amazon →
The good stuff
The protein profile is extraordinary. Two whole meats (deboned turkey and deboned chicken) provide highly digestible, minimally processed protein. Two meat meals (turkey meal and chicken meal) add concentrated protein density. Herring meal brings a fish-based protein with naturally occurring omega-3s. Five named animal protein sources in one formula gives cats the amino acid diversity that obligate carnivores need but rarely get from kibble.
Salmon oil provides direct EPA and DHA — the most bioavailable form of omega-3 for cats, who convert plant-based ALA extremely poorly. Chelated minerals (proteinates) are absorbed far more efficiently than the oxide and sulfate mineral forms used in most cat foods. The three-strain probiotic blend with chicory root prebiotic supports digestive health comprehensively. Glucosamine and chondroitin from chicken meal support joint health.
No corn, wheat, soy, artificial colors, flavors, or preservatives. The formula uses mixed tocopherols and rosemary extract for natural preservation.
The not-so-good stuff
Peas at position five are a legume filler that adds carbohydrates to a formula marketed as high-protein. Cats have limited ability to metabolize carbohydrates, so peas are essentially wasted calories. Dried plain beet pulp is a processing by-product used for fiber — functional but not premium. Natural flavor is vague and suggests palatability enhancement beyond what the actual meat provides.
The grain-free formulation puts this food in the periphery of the ongoing DCM discussion, though the research has focused primarily on dogs rather than cats, and the pea content here is moderate compared to some grain-free formulas. At roughly $3–4 per pound, CORE commands a premium over the Complete Health line — justified by the ingredients, but worth noting for budget-conscious cat owners.
How it compares
At A/90, Wellness CORE Cat joins Acana Cat (A/90) and Instinct Kitten (A/90) at the top of our rankings, trailing only Orijen Cat (A/91). It scores 2 points above Nulo Cat (B/88) and the 10-point gap over Wellness Complete Health Indoor (B/80) reflects genuine ingredient upgrades: an additional whole meat, herring meal, salmon oil, and chelated minerals.
Compared to Nulo Cat, CORE offers more protein diversity (5 animal sources vs. Nulo’s 2–3) and chelated minerals, while Nulo offers patented BC30 probiotics and a slightly simpler formula. Both are top-tier options; the choice comes down to whether you value protein complexity or formula simplicity.

The bottom line
Wellness CORE Cat earns an A grade (90/100) from KibbleIQ. The protein depth is exceptional — five named animal proteins, salmon oil, chelated minerals, and three probiotic strains deliver top-tier nutrition in kibble form. It’s a meaningful upgrade over Wellness Complete Health (B/80) that justifies the price premium. For cat owners who want the best kibble-format nutrition short of Orijen (A/91), Wellness CORE is among the strongest contenders. Shop on Amazon →
