While some people choose to feed their pets a vegan diet, it is important to consult with a veterinarian before making any significant changes to your pet's diet. Dogs are omnivores, meaning they can consume a plant-based diet, but it is crucial to ensure they receive all necessary nutrients such as protein, vitamins, and minerals. On the other hand, cats are obligate carnivores, meaning they require nutrients found in animal products to thrive. It is recommended to discuss your pet's dietary needs with a professional to ensure they remain healthy and happy on a vegan diet.
