Score breakdown
The overall score of 83/100 is a weighted sum of the six dimensions below. Each dimension shows what we found in this specific formula.
Weight 30% · Algorithm-computed score 82/100
Algorithm: first ingredient “Chicken” is named whole meat; 1 named animal ingredients in the top five; protein 33.7% on a dry-matter basis (target for this stage: 28%). Deductions: Concentrated corn protein used to lift the crude protein number without adding meat..
Weight 20% · Algorithm-computed score 70/100
Algorithm: first ingredient is a named animal source; among the top five, 0 by-product/unnamed and 1 plant-protein concentrate items.
Weight 18% · Editorially assessed score 92/100
AAFCO statement: Animal feeding tests using AAFCO procedures substantiate that this food provides complete and balanced nutrition for maintenance of adult cats.. Formulated-to-meet profiles are acceptable but weaker evidence than feeding trials, which caps the score here.
Weight 14% · Editorially assessed score 80/100
One recall event, announced in three waves between January and May 2019: a withdrawal of roughly 22 million cans of Science Diet and Prescription Diet wet dog food for elevated vitamin D traced to a supplier premix error. FDA issued Hill's a warning letter the same year over incoming-ingredient verification. No dry food, cat food or treats were affected, and nothing has been recalled since.
Weight 10% · Algorithm-computed score 95/100
Algorithm: about $2.61 per 1,000 kcal ($$ tier), normalized against same-species peers, wet and dry together (cheapest = 100, most expensive ≈ 15).
Weight 8% · Editorially assessed score 94/100
Owner ratings are consistently high across major retailers, with few recurring palatability complaints.
Pros and cons
What we like
- Feeding-trial validated, and built specifically around the three problems indoor cats actually have: weight, hairballs and litter-box odour
- 4.7/5 across roughly 5,700 Chewy ratings - one of the largest and highest review bases here
- 6% crude fiber with powdered cellulose is deliberately high to move ingested hair through
- 3,492 kcal/kg is moderate rather than low, so portions stay reasonable for a cat that grazes
What we don't
- Whole grain wheat second and corn protein meal third - two plant proteins high on the label
- About $3.16 per 1,000 kcal, more than double the cheapest dry cat food here
- High fiber means larger, more frequent stools
Ingredients & nutrition analysis
The first five ingredients tell most of the story:
This is a purpose-built formula rather than a generic adult diet. Moderate fat, 6% fiber with powdered cellulose for hairball transit, and highly digestible protein to cut stool volume and odour - all aimed at a cat that naps, grooms and grazes. It is feeding-trial validated, which most indoor formulas are not.
The label is the compromise. Whole grain wheat is second and corn protein meal third, so a meaningful share of the 31% protein is plant-derived, and a few owners have flagged that as the reason they switched away. At about $3.16 per 1,000 kcal it is also roughly twice the cost of the mid-priced dry foods here.
