Hill's Pet Nutrition, Topeka, KS, has introduced Hill's Science Diet Senior 11+ Age Defying cat food, which is formulated to help cats 11-years or older feel and act younger. The product contains an exclusive antioxidant bundle that helps defend the body and brain against aging, according to the company. In 30 days, consumers can expect to see a cat that is more interactive and playful, more alert and agile, and a cat that has fewer litterbox accidents, the company claims. The small kibble is easy to chew and digest, increasing lean muscle mass typically lost by older cats. It also supports healthy cognitive function and a radiant coat with fish oil and omega fatty acids. These benefits lead to an overall increase in engagement and daily well-being for cats entering their golden years.
