The evidence

The Verified Label

Every food on this site gets this exact panel — same fields, same order, sourced from the official label — so brands finally become comparable. Dots show where this food sits among all 283 dry cat foods we've verified.

Composition — dry-matter basis

why dry matter
Moisture hides the real recipe: dry food is ~5-10% water, wet food ~75-82%. Removing water puts every food on one scale, so these are the only nutrition numbers that can be compared across foods. As-fed label values shown small.
Protein 43.2%label: 38% min higher than 74% of dry cat foods
Fat 18.2%label: 16% min no corpus anchor for fat yet
Fiber 2.8%label: 2.5% max lower than 95% of dry cat foods
Est. carbohydrates ash not disclosed → 8% assumed, so this is an estimate ≈26.7%diabetic-check target <10% typical — the median dry cat food is 30%
Magnesium as fed: not yet verified
why 0.12% DM
A commonly cited veterinary target for helping manage struvite-crystal (urinary) risk in cats is magnesium under roughly 0.12% on a dry-matter basis. This is a general, label-checkable guideline — not a diagnosis, and not a substitute for your vet, especially for cats with a history of urinary issues.
 Not yet verifiedmagnesium no threshold to check — magnesium not in our verified record
Ash 8% assumed — not disclosed on label 8%as used in carb estimate no corpus anchor for ash yet

Standards & ingredients

AAFCO statement
what this means
Two kinds of AAFCO claims exist. Most foods are only "formulated to meet" nutrient profiles — a paper calculation. A smaller set carry the stronger claim: fed to real cats in AAFCO-procedure trials ("Animal feeding tests using AAFCO procedures substantiate…").
 Feeding trials ✓ · maintenance
First five ingredients (by pre-cooking weight)Salmon · chicken by-product meal · corn protein meal · rice flour · chicken meal
Named animal protein first; named meals onlyYes
Legumes in first 10 (FDA DCM inquiry)None
BHA / BHT preservativesNone on label
Carrageenan (thickener)None
Ethoxyquin
why unknown
When a fish-meal supplier adds ethoxyquin, U.S. rules don't require it on the finished label — so no label can prove its absence for recipes containing fish meal. We report this as a gap rather than guessing.
 None — no fish meal in this recipe

The maker

Who makes this — and how they back it up

The four questions the WSAVA nutrition guidelines tell you to ask a pet-food company. Every answer is sourced or marked as an undisclosed gap — never guessed. This is the "is it made competently?" axis that star-rating sites skip.
