A couple of my dogs eat dirt, one of the cats will eat anything vaguely like food. I have no idea why. I only know that hairballs from my brush are not safe. Its one of those odd ones. I admit, I searched Wiki for "eating disorders" and picked the interesting one. My first thought was Tony with anorexia, or Steve back after going through Project Rebirth. But pica was more fun. :D

(I think I will change it. It was a cool idea, which is less so in practice.)
