Our regular “raw recipe” is designed to emulate what cats eat in the wild. When they catch live prey, their meal includes the stomach contents of the animals, most of which are herbivores. To replicate that, we add small amounts of vegetables that also provide nutrients. Our transitional recipe is designed for cats just starting on a raw diet. It's all meat with a little kelp and sea salt for minerals, which is easier on the digestive system and more likely to appeal to finicky eaters. If your can't won't make the change to our regular recipes, they can do very well staying on the transitional recipe.
