Polybrominated diphenyl ethers (PBDEs) are a class of flame retardants that were commonly used on furniture. That is, until veterinarians noticed a rise in thyroid disease among indoor cats and research showed a link between PBDEs and the rise in thyroid disease. PBDEs were phased out starting in 2004. That’s the good news. The bad news is that the replacements for PBDEs may be just as bad. A study recently published shows a connection between thyroid disease in indoor cats and organophosphate esters (OPEs), which replaced many PBDEs.
