A Serious Correction

I was filled with shock as I read my contribution to your Vet Q&A; column “Feline Felicity” on Nov. 10 . The allowable magnesium content for cat foods was changed to .8%. The correct amount is .08% (measured in milligram percentage). A lower (not higher) magnesium content is imperative for alleviating the FUS problem. I want to correct this information immediately.
