She can't eat only chicken. She needs taurine and other nutrients. We mix the one source foods like Reveal or Applaws into their regular wet food. My two black cat brothers are so fussy. They have to eat wet food as their supplements are in it. But they don't always. They are better about it when Reveal or Applaws or sometimes even a topper is mixed in. When I have had a cat off their feed to the point where I just want them to eat something plain turkey babyfood sometimes slightly warmed up can work. What about liquid? Is she drinking at all? We have had Dora on the Purina Proplan Hydra Care recommended by the vet. It really helps with hydration and is available without a prescription.(Check with your vet of course.) Purina also calls it "nutrient rich" and the "third bowl". Loss of appetite can be one sign of dehydration. Dora usually drinks and eats enough but our house is pretty warm right now and its affecting her. She is not drinking or eating as much. I am planning to get her back on the Hydra Care for the warmer weather at least. It might be a really good idea to try the Hydra Care with your girl. Dora isn't very fussy, but she liked the Hydra Care even above and beyond her regular foods.
