9-Year Longevity Study in Cats

9-Year Longevity Study in Cats
While many factors affect the rate an individual ages, the cumulative effects of oxidative stress are considered a major contributor to the development of age-related conditions.

Enhancing the diet of senior cats with a nutrient blend that includes antioxidants may help combat the impact of oxidative stress and help cats live longer, healthier lives.1

Purina's research

purinas research 9 year study in cats

Purina conducted a groundbreaking 9-year study which demonstrated that nutrition can extend the healthy lives of cats.1

In this long-term feeding study, 90 healthy mixed-breed cats entered the study between 7 and 17 years of age, and remained in the study for life.

The cats were divided into three groups, each fed different diets:

Purina’s blend of nutrients was scientifically proven to increase life span by an average of one year.1 

This pioneering study also showed improvements in multiple health parameters in older cats


Increased skin fold thickness, a marker of improved nutritional status



Maintenance of a healthy body weight and lean body mass

Key things to remember

  • Nutrition can play a key role in extending the healthy life of cats.
  • A 9-year study showed that a nutrient blend, with antioxidants, essential fatty acids and a prebiotic can extend the healthy lives of cats.
  • Cats fed a proprietary nutrient blend better maintained body weight, lean body mass and had slower age-related decreases in several health measures.
