The advantages of nori for cats

Including seaweed in your cats’ diet has several benefits. It will boost their digestive system, immune function, and leave them with a shiny coat.

  • Digestive system

Seaweed is a fantastic source of prebiotics that can improve the growth of good bacteria in your cat’s digestive system when they regularly eat it. At the same time, it restricts the growth of harmful bacteria.

  • Immune function

Our immune systems are linked to gut health, and with cats, it’s no different! If your cat has a healthy digestive system, they’re less likely to get sick.

  • Appearance

Admit it – we all stare at cats with shiny coats! If you want your cat to be the neighborhood envy, you should start feeding them seaweed. The omega-3 fatty acids in seaweed will thicken your cat’s coat and give it a silky smooth shine.


There are eight types of edible seaweed, and the nutrient content of each is different. Nori contains the following:

  • Vitamins A, B1, B2, C, E, K
  • Calcium
  • Copper
  • Folate
  • Iron
  • Manganese
  • Potassium

The disadvantages of nori for cats

When your cat overeats seaweed containing iodine, it can affect its thyroid health. Cats are prone to developing hyperthyroidism which can lead to several health concerns.

If you include seaweed in their diet, you should limit it to one or two small portions per week.

Why Can Cats Eat Nori?

Nori is non-toxic, which makes it safe for cats to eat. Your cat’s diet should mainly consist of meat, but 5 – 10% of it can be vegetables.

Technically, seaweed isn’t a vegetable, but it does provide some of the many nutrients that fruits and veggies do. Seaweed also digests quickly, making it gentle on your cat’s stomach.

How To Serve Seaweed To Your Cat

Serving your cat Nori is simple! You just have to find the right quality seaweed, and you’re good to go.

You can visit your local vet, pet shops, and health or grocery stores to see who stocks the best seaweed. The seaweed you choose should be preservative-free, spice-free, and unprocessed.

If not, it can be harmful to your cat.

You should know that feeding your cat Nori might not go as planned the first time. Some cats dislike the taste and texture of it. You can start by shredding the seaweed sheets and sprinkling them over wet cat food. If your cat eats thiswithout any problems, you can give them seaweed crisps as a snack.

Edible Nori Alternatives

Nori is probably the most popular choice from the eight types of edible seaweed there is. If your cat doesn’t like it, you can try one of these alternatives:

Acadian sea kelp

Kelp grows in cold water and contains calcium, iron, magnesium, protein, and more! It makes a nutrient-rich ingredient in homemade cat food or treats.

Blue-green algae

Blue-Green algae contain beta carotene, glycogen, and trace minerals that can all improve your cat’s brain activity.


Dulse is a green-seaweed rich in minerals and other nutrients. It can help prevent cancer and improve your cat’s digestive health.

Dulse is best used as a fine powder over your cat’s food.

Irish moss

Irish moss can be brown, green, purple, or red. It supports your car’s organs like the bladder, kidney, and lungs.


Horsetail kelp (or Kombu) can be served marinated, roasted, or sautéed. It supports kidney, liver, and stomach functions.

Sea lettuce

Sea lettuce is rich in iron and tastes like an oyster. It has fewer minerals than other seaweeds but can still benefit your cat.


Wakame is traditionally used as a medicine and can burn fatty tissues in cats. It prevents cancer diabetes and helps cats to regulate their metabolism.

Like Nori, it contains omega-3 fatty acids and different minerals and vitamins. You should also serve all of these Nori alternatives in moderation and never replace your cat’s meals with it.
