Cotton candy is generally vegan, as it is made from sugar and food coloring. However, some brands of cotton candy may contain trace amounts of gelatin or other non-vegan ingredients, so it's important to check the ingredients list before consuming. If vegan-friendly brands (without any animal testing or animal-based products or ingredients) are not available, you can make your own cotton candy at home with organic sugar and natural food dyes (if you must have a colored candy cotton). You can just make sugar floss without any natural flavoring or artificial coloring by just spinning organic sugar to enjoy on your vegan diet.
