There are many things that could make Lucy skinny all of a sudden. Intestinal worms, kidney disease, neoplasia or inadequate calories are all potential causes. I would recommend to take Lucy into the vet for a fecal exam and some bloodwork. The fact that she doesn't want to eat could be an indicator that she does not feel good. Best to get her in quickly as diseases are easier to treat early. I hope this helps!
