Purina ONE High Protein Dry Cat Food +Plus Urinary Tract Health - 16

In this review of Purina ONE High Protein Dry Cat Food +Plus Urinary Tract Health Formula, the bottom line is simple: it is best for adult cat owners who prioritize urinary tract support while keeping protein levels high. The reviewer found the recipe, made with real chicken, provides the protein needed for strong muscles and a healthy heart, and its low magnesium formulation and urinary pH support make it a clear choice when urinary care is the primary concern. This review focuses on how the formula balances nutrition, digestibility and palatability for everyday feeding.

Key Features

• Real chicken protein: Provides higher-quality protein to help maintain strong muscles and support a healthy heart.
• Urinary tract support: Low magnesium and a formula that helps reduce urinary pH to lower the risk of urinary problems.
• SmartBlend digestibility: An easily digestible mix of high-quality ingredients designed to be gentle on the stomach.
• Antioxidant support: Four antioxidant sources are included to support a healthy immune system over time.
• Crunchy kibble: Crunchy bites with added calcium help support strong teeth and healthy gums while delivering flavor.
• Made in U.S. facilities: Crafted in Purina-owned U.S. facilities, which some owners prefer for manufacturing oversight.

Who It's For

This food is a good fit for adult cat owners whose pets need urinary tract management and who also benefit from a higher-protein diet. It suits cats that respond well to crunchy kibble and owners looking for a complete and balanced everyday formula with added immune and dental support.

It may be less suitable for cats with known food sensitivities that cause vomiting or diarrhea for some individuals, and for picky eaters who refuse the texture or flavor. Owners of kittens or cats with specialized veterinary diets should look elsewhere.
