In summary, the results of this study demonstrated high levels of PBDEs in cats and that fish-flavoured cat foods contained higher levels of PBDEs than other feeds. The level of PBDEs was not significantly higher in cats with hyper- thyroidism than the levels in the other groups of cats, although there was a lot of individual variation. Currently, there is no evidence that PBDEs are responsible for the rise in the incidence of hyper- thyroidism within the feline population. However, this study produced some inter- esting hypotheses, and this area warrants further investigation.
