Vomiting, diarrhoea, poor appetite and lethargy; long-term excess iodine may be linked to thyroid problems, showing as weight change, a dull coat, low activity or a changed appetite.

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

**Soak it well and boil it soft, then chop it**, and keep it a tiny occasional treat; **never give cats salted kelp sprout snacks or salty kelp soup**, and **never feed it for claimed iodine or detox benefits**; complete cat food stays the main diet.
