Note: While dogs are biologically omnivores and can adapt to plant-based diets more easily, cats require extra care. Any dietary changes for cats should be supervised by a vet – ideally one experienced in balanced plant-based nutrition. If a vet rejects the idea of transitioning to a plant-based diet, it’s important to know that experts and pet food associations confirm that cats can thrive and tend to be healthier on such diets.
