Best Senior Dog & Cat Food

Pros

• hillspet.com Adult 7+ Chicken Recipe cat PDP 2026-09-02: recommended for adult cats 7+ years of age. Not recommended for kittens or pregnant or nursing cats. Animal feeding tests using AAFCO procedures substantiate that Hill's Science Diet Adult 7+ Chicken Recipe Cat Food provides complete and balanced nutrition for maintenance of adult cats. That is adult maintenance — AAFCO has no senior profile.
• 490 kcal/cup (3926 kcal/kg). Mature-adult cup/gram table. Sizes named: 4 lb, 7 lb, 16 lb. 7-day transition. Adjust feeding to maintain optimal weight. Official bag photo from the Hill’s U.S. shop CDN (shop.hillspet.com SKU 7104).
• shop.hillspet.com SKU 7104 2026-09-02: one-time $22.99 for the 4 lb bag; autoship optional, not required. This row is cats. It is not the Adult 7+ dog bag and not Adult 11+ cat.

Cons

• PDP copy about heart, kidneys, and bladder ‘supported by antioxidants and balanced minerals’ is support language on an OTC complete diet. It is not Hill’s Prescription Diet k/d. We are not veterinarians.
• ‘U.S. Veterinarians’ #1 Recommended Brand’ on the PDP is marketing. We did not score it.
• Dry kibble is not a water bowl. Complete and balanced is a labeled claim, not a homemade recipe. Transition over 7 days as the PDP says.

Pros

• iams.com Healthy Senior PDP 2026-09-02: dry cat food with chicken as the #1 ingredient for indoor and outdoor cats 11 years and older.

Cons

• AAFCO nutritional adequacy sentence is not on this PDP. The page says complete and balanced for maintenance. We do not invent a senior AAFCO line. Quality is scored without the AAFCO bonus.
• A hidden calculator field contains 399 kcal ME/cup — we did not treat a hidden form value as a labeled calorie statement (same rule as IAMS kitten). No maker USD. ‘Veterinarians recommend IAMS’ is marketing.
