Iodine content of commercially-prepared cat foods

Abstract

Twenty-eight varieties of commercially-available cat food (23 canned, 5 dried) were analysed for iodine. The iodine concentration varied from less than 0.37 µmol/kg to 41.8 µmol/kg, wet weight (less than 1.48 µmol/kg to 167 µmol/kg, dry weight). Excessive or insufficient iodine intake or wide swings in iodine intake over prolonged periods may contribute to thyroid disorders in cats.
