Vegans shouldn’t have pets. If the ethos of veganism is consent for the things others give then it should be thought of as slavery for them to own any, especially if they feed a carnivorous animal a vegan food alternative.
This is a really bad take. Not all vegans are vegans for the same reason. Often pets are adopted from e.g. shelters to protect them from a worse fate. You can have a pet while providing it with freedom.
