The short answer: This is one of the closest grain-free matchups in the mid-premium tier — two genuinely solid chicken-based kibbles separated by a hair. Earthborn Holistic leads its Primitive Feline recipe with fresh chicken in the very first slot, then backs it with chicken meal and pairs the protein with pumpkin and sweet potato, two gentle whole-food carbohydrates most cats digest comfortably. Solid Gold’s Indigo Moon opens with concentrated chicken meal, then layers in whole egg for complete protein and a probiotic blend to support digestion, though it leans on a potato-and-pea carbohydrate base. Both deliver quality named animal proteins and skip grains entirely. If you want a simpler panel, fresh meat leading, and often a lower price, Earthborn Holistic is your pick. If you prioritize the most concentrated animal protein per cup plus added egg and probiotics, Solid Gold edges in front. Either way, both bowls serve most cats well.

The scores

Earthborn Holistic Primitive Feline Grain-Free: C (73/100) — Chicken, Chicken Meal, Pumpkin, Sweet Potato, Tapioca.

Solid Gold Indigo Moon Chicken & Eggs: C (74/100) — Chicken Meal, Potatoes, Canola Oil, Peas, Chicken.

How the ingredients compare

Here are the first five ingredients on each label — the part of the panel that drives most of the score under our published rubric:

Earthborn: Chicken, Chicken Meal, Pumpkin, Sweet Potato, Tapioca

Solid Gold: Chicken Meal, Potatoes, Canola Oil, Peas, Chicken

Read the labels side by side and the difference is mostly about sequencing. Earthborn Holistic lists fresh chicken first — whole muscle meat weighed with its natural water — then chicken meal, a concentrated protein with the moisture already removed. That one-two puts both forms of named poultry up top. Solid Gold flips the order, opening with chicken meal so more animal protein is packed into every cup, then placing fresh chicken further down alongside whole egg, a complete protein. The carbohydrate stories diverge too: Earthborn Holistic uses pumpkin and sweet potato, recognizable whole-food carbs, with tapioca as a binder. Solid Gold builds on potatoes and peas — a legume-and-starch base that works but reads as less distinctive — and adds canola oil as a plant fat. Both fold in supporting nutrients, with Solid Gold’s probiotic blend the clearest digestive extra.

Where Earthborn pulls ahead

Fresh chicken leads: Earthborn Holistic puts whole-muscle chicken in the very first slot before any meal, so the recipe opens with fresh, named poultry. It still backs that with chicken meal for concentrated protein, giving the formula both forms of animal protein right at the top of the panel. Shop on Amazon →

Gentler whole-food carbs: Rather than a legume-heavy base, Earthborn Holistic pairs its protein with pumpkin and sweet potato — recognizable, gentle carbohydrates most cats digest comfortably — using only tapioca as a simple binder. It’s an easy panel to read and reassuring for sensitive stomachs.

Simpler panel, friendlier price: The recipe keeps its supporting cast short and is frequently the more affordable bag on the shelf. For owners who want quality grain-free nutrition without paying a premium or parsing a long ingredient list, that combination is genuinely appealing.

Where Solid Gold holds its own

Meal-first protein density: By opening with chicken meal — concentrated poultry with its water already cooked off — Solid Gold packs more actual animal protein into each cup than a fresh-meat-first label often delivers once moisture is accounted for. For a high-protein feeding goal, that ordering counts. Shop on Amazon →

Whole egg adds complete protein: The Indigo Moon recipe folds in whole egg, one of the most complete and digestible proteins available, rounding out the amino-acid profile alongside the chicken. It’s a meaningful quality marker that Earthborn Holistic’s panel doesn’t match.

Probiotics for digestion: Solid Gold blends in probiotics aimed at supporting gut health and nutrient absorption — a useful extra for cats with finicky digestion. It’s the clearest functional addition on either label and a fair reason to lean its way.

The bottom line

Stack these two up and you’re looking at a near-tie between two well-built grain-free kibbles in the same mid-premium tier. Earthborn Holistic wins on fresh chicken leading the panel, gentle pumpkin-and-sweet-potato carbs, a simpler ingredient list, and usually a lower price. Solid Gold answers with chicken meal first for denser per-cup protein, whole egg for complete protein, and a probiotic blend for digestion — advantages that, taken together, nudge it barely ahead. The trade-off is its less distinctive potato-and-pea carbohydrate base. There’s really no wrong choice here. Pick Earthborn Holistic if fresh-meat-first, recognizable carbs, and value matter most. Pick Solid Gold if you want maximum animal protein per cup plus the egg-and-probiotic extras. Most cats would thrive on either, so let your budget, your cat’s digestion, and what’s reliably stocked near you settle it.
