Composition — dry-matter basis

why dry matter
Dry food is ~5-10% water, wet food ~75-82%, so as-fed numbers are on two different scales. As-fed values shown small. How the conversion works →
Protein 43.2%label: 6.7% min lower than 83% of wet cat foods
Fat 14.8%label: 2.3% min no corpus anchor for fat yet
Fiber 6.5%label: 1% max no corpus anchor for wet-food fiber yet
Est. carbohydrates ash not disclosed → 8% assumed, so this is an estimate ≈16.1%diabetic-check target <10% higher than 87% of wet 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

Urinary fit — can't assessMagnesium is not disclosed on this label, so the urinary/struvite check cannot be run — most cat food labels omit it entirely (only a small share of the cat foods we've verified disclose magnesium at all).

Too many estimated carbs for a low-carb target≈16.1% carbohydrate (dry-matter, estimated) is over the ~10% DM target some vets use for diabetic/low-carb cats. Estimate only — not a lab measurement. See lower-carb options →

The maker

Who makes this — and how they back it up

The five 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

Owns/operates its own plants; Mars opened a new $450M Royal Canin factory in Lewisburg, Ohio in 2025 (confirmed via mars.com press release).

AAFCO feeding trials Not stated

Ambiguous: Royal Canin's answer to WSAVA's feeding-trial question says 'nutrient profiles and/or feeding trials' and does not say which retail foods had AAFCO feeding trials. every one says 'formulated to meet the nutritional levels established by the AAFCO Dog Food Nutrient Profiles' and none carries an 'animal feeding tests' statement.

Publishes quality-control testing Yes — sourced
