Cats can eat seaweed in moderation, and it can be a nutritious treat for them providing vitamins, minerals, fiber, and omega-3 fatty acids that promote coat health, digestion, and immunity. However, it should not replace their primary meat-based diet as cats are obligate carnivores. Seaweed is safe when plain and unseasoned but should be given sparingly due to its high iodine content, which can cause thyroid issues if consumed in excess. Common safe types include nori, kelp, dulse, and wakame. Avoid processed seaweed with added salt or spices, as these can be harmful to cats.
