What does it mean if the bottom of my feet are yellow?

Carotenemia?: Yellow palms and soles will tip a savvy physician off to someone who likes yellow vegetables, especially carrots. It's quite common in healthy-lifestyle folks. I trust that your eyes are not yellow from mild jaundice and that the cat did not urinate in your shoes. If this isn't you, talk with your physician next time you visit. If you feel well i would not be concerned.
