Plain-English summary
A study found that many commercial cat foods may not have enough iodine, which could be linked to an increase in hyperthyroidism (a common thyroid problem) in older cats. Since the late 1970s, the amount of iodine recommended for cat food has changed, and some foods might not meet the new guidelines. This could mean that cats are not getting enough iodine in their diets, potentially leading to health issues like hyperthyroidism. Pet owners should consider discussing their cat's diet with their veterinarian to ensure it meets the necessary iodine levels.

Abstract
UNLABELLED: ARTICLE RATIONALE: Since the late 1970s, there has been a significant increase in the prevalence of feline hyperthyroidism (FH). It is now recognized worldwide as the most common endocrinopathy of older cats, resembling toxic nodular goiter of older humans in iodine-deficient areas. The purpose of this article is to identify the potential for iodine concentrations in the diet to contribute to the etiology of FH. HISTORICAL CONTEXT: Iodine concentrations of commercial cat foods vary widely. A review of historical iodine recommendations revealed that the units of iodine supplementation changed in the 1970s. Given this change, foods minimally supplemented since the late 1970s would have been iodine deficient for most cats. PRACTICAL RELEVANCE: Iodine supplementation of commercial cat foods should be evaluated in the light of the iodine recommendations revised in 2006. Foods may remain deficient in iodine if supplemented at the minimum recommended concentration, possibly contributing to the development of FH.
