one of our cats eats fingernail parings (and shredded wheat, which he will actually beg for - maybe he likes the fingernail parings because shredded wheat kind of taste like them).

Pica for an eating disorders fill had seriously never occurred to me, though -- I think the idea's kind of awesome. I saw it in the prompt list and my only thought was "anorexia/bulemia prompt. Do not want."

(I vote for no more all-caps, btw. I find them hard to read, though I don't mind them in the input box.)
