While it is possible for some pets to follow a vegan diet, it is important to consult with a veterinarian before making any significant dietary changes for your pet. Dogs, for example, are omnivores and can thrive on a well-balanced vegan diet with proper supplementation. However, cats are obligate carnivores and have specific nutrient requirements that are typically found in animal-based products. It is crucial to ensure that your pet's nutritional needs are met when considering a vegan diet for them.
