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 33.3%label: 30% min lower than 87% of dry cat foods
Fat 16.7%label: 15% min no corpus anchor for fat yet
Fiber 3.3%label: 3% max lower than 89% of dry cat foods
Est. carbohydrates ash not disclosed → 8% assumed, so this is an estimate ≈37.8%diabetic-check target <10% higher than 88% of dry cat foods
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

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…").
 Formulated to meet · maintenance
First five ingredients (by pre-cooking weight)Chicken by-product meal · whole grain ground corn · wheat flour · chicken fat (preserved with mixed tocopherols) · dried yeast
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.

Owns its manufacturing Owns its plants

Facilities are described as Diamond's own in Meta, Missouri (HQ); Gaston, South Carolina; Lathrop, California; Ripon, California; Dumas, Arkansas; Frontenac, Kansas; and Rushville, Indiana. Diamond Pet Foods is well known industry-wide as a company that owns and operates its own plants rather than co-packing.

Employs a qualified nutritionist Undisclosed

Diamond states it uses an internal team spanning veterinary medicine and companion-animal nutrition disciplines, but does not name a specific individual or state a board certification for any staff member on this or other pages found. Cannot confirm true or false with a real source, so left null rather than guessed.

source →
AAFCO feeding trials Undisclosed

No feeding-trial AAFCO statement found on the 8 labels we’ve verified for this brand, and no company-wide claim was found either. Most pet foods are only "formulated to meet" AAFCO profiles (a paper calculation) rather than fed to real animals in trials — this is common, not necessarily a red flag.

Peer-reviewed research Unconfirmed

71 PubMed-indexed papers carry this brand's name in an author affiliation — but without a recognized pet-nutrition research arm we can't confirm these are the company's own studies rather than unrelated name matches (surnames, the taxonomic family "Canidae", institutions). We don't count it as confirmed research.
