She might have an allergy to Beef or lamb. My cat Huly would get sicke with in 48 hours of eating Salmon. We had a blood allergy test ran on him (as he also has other sinus issues) and he is allerigic to Beef, ALL SEAFOOD, Venison, Eggs, Corn, White Potato, Brewers Yeast, Tomato, Alfalfa, and Pumpkin.
I have never seen or heard of a cat that is allergic to seafood but trying to find food and treats for him has been difficult. I wonder if Chloe is the same.
