Our Grain Free Weight Control/Hairball Recipe is a non-GMO, grain free dry food for adult, senior, and less active cats. Made with the highest quality chicken meal and whitefish meal—two of cats’ favorite proteins—it contains 7% fiber for optimal hairball prevention. This recipe is Uristic, which means optimized for long term urinary tract health. The formula’s 1% Methionine, occurring naturally in our fresh ingredients and supplemented to optimal levels, raises the acidity of urine. This helps break down urine crystals and reduces inflammation and the chance of urinary tract infections.
