Can cats eat seaweed?

Seaweed is a common sight at beaches and oceans around the world. Its unique appearance and flavor make it an intriguing snack for humans. As a cat owner, you may wonder if seaweed is safe for your feline friend or if cats can eat seaweed.

Is Seaweed Safe for Cats?

In most cases, seaweed itself is not toxic to cats. Many types such as nori, wakame, and kombu are safe in small amounts. However, there are a few precautions to keep in mind:

  • Cats have difficulty digesting plant matter. Large amounts of seaweed may cause digestive upset.
  • Raw seaweed can contain parasites or bacteria. Only offer cooked seaweed to cats.
  • Seaweed can have a high sodium content. Limit intake to avoid hypertension.
  • Cats should not eat seaweed salad from sushi restaurants, as it may contain onion, garlic, oils, or other ingredients that are toxic to cats.

Benefits of Seaweed for Cats

Though seaweed does not provide complete nutrition for cats, it can offer some health advantages when given occasionally in moderation:

  • Seaweed is a good source of antioxidants that support immune health.
  • It provides amino acids like taurine that cats require in their diet.
  • Some types of seaweed contain omega-3 fatty acids to promote skin/coat health.
  • The fiber in seaweed supports healthy digestion and weight management.

How to Offer Seaweed Safely

Follow these tips to give your cat seaweed responsibly:

  • Choose dried, low-sodium seaweed and rehydrate before serving. Rinse well.
  • Cook seaweed first to remove any bacteria or parasites. No raw seaweed.
  • Introduce slowly in tiny amounts and watch for signs of stomach upset.
  • Cats may enjoy seaweed flakes mixed into their regular food. Offer just a sprinkling.
  • Never give cats seaweed in place of a balanced, cat-appropriate diet. It is not a dietary staple.


Seaweed can be part of a healthy, varied diet for cats in moderation. Offer small amounts of cooked, low-sodium seaweed occasionally as a snack or supplement. Avoid sushi seaweed and raw seaweed due to toxicity risk. Check with your vet before introducing new foods. With some care and supervision, most cats can enjoy seaweed from time to time.
