It's possible that her teeth could hurt. If she has a bad tooth, it would be painful for her to eat. Your vet can give her an appetite stimulant but you've got to get to the bottom of why she isn't eating and it may be the anemia. One of my cats was just recently diagnosed w/anemia and she's now on Epogen injections. It's expensive but it's worth it, if it fits into your budget. It helps to build red blood cells. According to my vet, iron supplements won't do it because they only support red blood cells and, if your cat is anemic, she's hardly producing any. However, I'd start small first: have her teeth checked and the inside of her mouth to be sure there isn't anything obstructing her swallowing, etc. Then go from there w/the process of elimination. Good luck and please keep us posted.
