Laver (Nori)

**Laver (nori) is likewise very high in iodine**, and a cat's small body tolerates little surplus, so regular or large amounts disturb thyroid function and **cats with thyroid disease must avoid it**; **seasoned nori snacks bring salt, sugar and oil** on top.

Vomiting, diarrhoea, poor appetite and lethargy; the salt in seasoned nori snacks may cause unusual thirst and frequent urination, and long-term excess iodine may be linked to thyroid problems.

Stop feeding and watch; **contact a vet immediately** for persistent vomiting, diarrhoea, lethargy or unusual thirst, or if a thyroid problem is suspected, and never induce vomiting or give human medicine at home.

**Even plain, unseasoned sushi nori stays a tiny rare taste**; **never give cats seasoned nori sheets or nori-flavoured snacks**; cook it soft before chopping, and **never feed it for claimed iodine benefits**; complete cat food stays the main diet.

**Laver (nori) is also very high in iodine**, so a small amount can exceed a dog's needs, and long-term or large servings disturb thyroid function, especially in dogs already treated for a thyroid condition; **seasoned nori snacks bring salt, sugar and oil**.

Vomiting, diarrhoea, poor appetite and lethargy; the salt in seasoned nori snacks may also cause unusual thirst and frequent urination, and long-term excess iodine may be linked to thyroid problems.

Stop feeding and watch; **contact a vet immediately** for persistent vomiting, diarrhoea, lethargy or unusual thirst, or if a thyroid problem is suspected, and never induce vomiting or give human medicine at home.

**Plain sushi nori is unseasoned but still belongs in the tiny occasional category**; **never feed seasoned nori sheets, nori snacks or salty seaweed crisps**; soak it and cook it soft before chopping, and **never feed it for claimed iodine benefits**.
