Have you tried any of the new Fancy Feast canned foods?? I know they are pricey, but my finicky guys eat it. I buy it as a treat mainly, but my newest cat in the family, who is FIV+ and about 12 or so, has practically no teeth and eats mainly wet food. He doesn't care for friskies, but loves Fancy Feast, and really enjoys the new stuff.

One of our cats at the shelter is on a raw food diet. I think the shelter mgr gets it freeze dried or something like that. They have a lot of it available on one site I checked out early this week http://www.onlynaturalpet.com
They deal in only holistic, natural foods for dogs and cats. If you haven't seen the site before, you might want to check it out. They have all kinds of foods, treats and things like that.

Good luck, and I hope your kitty starts to feel better, and eat more on her own shortly!
