Purina Pro Plan LiveClear Adult 7+ Prime Plus Longer Life Formula
The most research-heavy senior cat food here: 38% protein, feeding-trial validated, and a documented 47% reduction in active Fel d 1. It is also the priciest dry cat food per calorie, and half the technology is wasted if nobody in the house is allergic.

Nine voluntary recalls since 2011, most of them small and lot-specific. Recent events cluster in the prescription channel: a December 2022 mislabelling of Pro Plan Veterinary Diets EN cans and a February-March 2023 elevated-vitamin-D withdrawal of EL Elemental dry food. No mainstream retail Pro Plan dry food has been recalled.

Owner ratings are consistently high across major retailers, with few recurring palatability complaints.
Pros and cons
What we like
- 38% protein at age 7+ - Purina deliberately resists the industry habit of cutting protein in senior diets
- Feeding-trial validated, with a proprietary blend Purina states is proven to improve and extend life in cats over 7
- Also carries the LiveClear egg-protein technology, which reduces active Fel d 1 in cat hair and dander by an average of 47%
- Guaranteed live Bacillus coagulans, plus glucosamine, chondroitin and L-carnitine
What we don't
- About $3.68 per 1,000 kcal - the most expensive dry cat food here per calorie
- Poultry by-product meal and corn protein meal occupy slots two and three
- Only sold in small bags, and the LiveClear allergen benefit is irrelevant to households without cat allergies
Ingredients & nutrition analysis
The first five ingredients tell most of the story:
Two ideas are bundled here. Prime Plus is the senior half: 38% protein held high on purpose, a proprietary nutrient blend Purina says is proven to extend healthy life in cats over 7, plus guaranteed live probiotics, glucosamine and L-carnitine. LiveClear is the other half - an egg-derived protein that binds Fel d 1 and cuts the active allergen in hair and dander by an average of 47% from about the third week.
That combination costs $7.20/lb from a 5.5 lb bag, roughly $3.68 per 1,000 kcal and the most expensive dry cat food here. If no one in the household is allergic, you are paying for a benefit you cannot use; the senior nutrition alone is available more cheaply elsewhere. The ingredient panel is also unremarkable, with poultry by-product meal and corn protein meal at positions two and three.
