Score breakdown
The overall score of 82/100 is a weighted sum of the six dimensions below. Each dimension shows what we found in this specific formula.
Weight 30% · Algorithm-computed score 81/100
Algorithm: first ingredient “Chicken” is named whole meat; 1 named animal ingredients in the top five; protein 32.6% 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 87/100
Algorithm: about $3.88 per 1,000 kcal ($$$ tier), normalized against same-species peers, wet and dry together (cheapest = 100, most expensive ≈ 15).
Weight 8% · Editorially assessed score 93/100
Owner ratings are consistently high across major retailers, with few recurring palatability complaints.
Pros and cons
What we like
- Feeding-trial validated, and built on the same enhanced-botanical-oil brain-metabolism research as the dog version
- Chicken leads, with controlled phosphorus and high-quality protein aimed at supporting ageing kidneys
- 30% protein with 12.5% fat and only 3% fiber - a digestible profile for an older cat with a smaller appetite
- 4.7/5 across roughly 760 ratings, with owners most often reporting improved interaction and playfulness
What we don't
- About $3.88 per 1,000 kcal and only sold in small bags - the most expensive dry cat food here apart from Prime Plus
- Corn protein meal fourth and brewers rice second
- Smaller review base than the Hill's indoor and kitten formulas
Ingredients & nutrition analysis
The first five ingredients tell most of the story:
This is the feline counterpart to Hill's Senior Vitality dog food and rests on the same research: enhanced botanical oils intended to give an ageing brain an alternative fuel source as glucose metabolism shifts. It is feeding-trial validated, leads with chicken, and holds phosphorus and protein quality in a range intended to support ageing kidneys.
Cost is the limiting factor. At $6.67/lb from a 6 lb bag it is about $3.88 per 1,000 kcal, second only to Prime Plus among dry cat foods, and Hill's sells no larger size. Against Pro Plan Prime Plus it offers less protein (30% versus 38%) and no allergen benefit, but a deeper feeding-trial programme and a phosphorus level that is more carefully managed for senior kidneys.
