Score breakdown
The overall score of 66/100 is a weighted sum of the six dimensions below. Each dimension shows what we found in this specific formula.
Weight 30% · Algorithm-computed score 47/100
Algorithm: first ingredient “Wheat” is whole grain / named fat; 0 named animal ingredients in the top five; protein 30.3% on a dry-matter basis (target for this stage: 28%). Deductions: Named by-product meal; Plant protein concentrate — dilutes animal share.
Weight 20% · Algorithm-computed score 47/100
Algorithm: first ingredient is not a named animal source; among the top five, 1 by-product/unnamed and 1 plant-protein concentrate items.
Weight 18% · Editorially assessed score 82/100
AAFCO statement: Formulated to meet the nutritional levels established by the AAFCO Cat Food Nutrient Profiles for maintenance.. Formulated-to-meet profiles are acceptable but weaker evidence than feeding trials, which caps the score here.
Weight 14% · Editorially assessed score 88/100
Four recalls: a 2006 vitamin D3 excess that the company self-detected and veterinarians widely praised as a textbook response, two 2007 melamine-era withdrawals, and a January 2023 mislabelling advisory on a single lot of a veterinary renal diet. No retail dog or cat food has been recalled since 2007.
Weight 10% · Algorithm-computed score 89/100
Algorithm: about $3.55 per 1,000 kcal ($$$ tier), normalized against same-species peers, wet and dry together (cheapest = 100, most expensive ≈ 15).

Pros and cons
What we like
- Formulated for a specific, narrow group - cats over 11 - with an easy-to-chew kibble tested on senior cats
- Phosphorus capped at 0.88% max and high-quality protein to support ageing kidneys
- HealthyAge7 complex covers seven targets: appetite, digestion, mobility, skin, kidneys, brain and immunity, with EPA, DHA, glucosamine and chondroitin declared
- Royal Canin has not recalled a retail cat food since 2007
What we don't
- Wheat and corn are the first two ingredients; chicken by-product meal does not appear until third
- 28% protein is the lowest of any dry cat food here apart from Royal Canin Indoor
- About $3.55 per 1,000 kcal, and only 145 Chewy ratings back it - the thinnest review base in this ranking
Ingredients & nutrition analysis
The first five ingredients tell most of the story:
Royal Canin draws the line at 11 rather than 7, and everything about this food follows from that: an easy-to-chew kibble designed and tested on senior cats, phosphorus capped at 0.88% max, and the HealthyAge7 complex covering appetite, digestion, mobility, skin, kidneys, brain and immunity with EPA, DHA, glucosamine and chondroitin all declared.
It is the weakest label among the senior foods - wheat and corn lead, chicken by-product meal is third, and 28% protein is low for an ageing cat that needs to hold muscle. Add roughly $3.55 per 1,000 kcal and a review base of just 145 ratings, and this is a food to choose for a specific problem, not as a general senior diet.
