Yes, cats can eat seaweed in moderation.
Also known as sea vegetable, seaweed is considered a superfood because it contains good levels of dietary fiber, vitamins, and minerals. It is a form of algae that grows not just in the sea, but even in lakes, rivers, and other bodies of water. There are over 12,000 species of seaweed appearing in various colours such as green, red, and brown. Acadian sea kelp, dulse, Irish moss, nori, kombu, wakame, and sea lettuce are examples of edible seaweed that cats can eat.
Cats can receive many health benefits from consuming seaweed on a regular basis. You can see an improvement in your kitty’s digestive and immune systems thanks to the fiber, antioxidants, and prebiotics found in seaweed. Additionally, seaweed can help combat skin allergies and leave your cat with a sleeker and shinier coat.
How to feed seaweed to your cat: Similar to how dogs are fed seaweed, make sure you select unflavoured human-grade seaweed to give to your cat. Check the label and do not pick one that is prepared with poisonous ingredients such as salt, garlic, and onion. You should also watch for harmful preservatives and spices. You can feed seaweed to her directly or place it over her regular meal.
Before feeding her seaweed for the first time, make sure to get your vet’s approval. Find out how much and how often you can give it depending on your cat’s age, size, and needs. Let your cat initially try a small amount and observe her mood, behaviour, eating, and litter box habits for the next 24 hours. Contact your veterinarian for any strange symptoms that pop up.
In summary: Seaweed may not be a top-of-mind vegetable option for cats, but it contains many nutrients that can improve your cat’s well-being. By giving it as an occasional treat or adding it in her meals, it may help reduce digestive issues she may be experiencing.
