Updated January 2025

While a little grain in your kitty’s diet isn’t the worst thing in the world, a grain-free cat food will contain far more of the meaty ingredients that your cat would naturally eat. For instance, by cutting out rice, wheat, and corn, there is that much more room for turkey, beef, and fish in each savory bite of cat food. With so many recipes and brands out there, it’s not always easy to find the perfect grain-free cat food for your furry friend, so we wholeheartedly recommend researching to find out which formulas best match your cat’s health needs and dietary preferences.
