GimCat Nutri Vitamin Bites with Chicken

Why does everything always have to be made worse in the name of improvement? For 3 years, my tomcat has been taking these vitamin tablets, but now I can't give them to him anymore because they're now made with chicken. My cat suffers from a chicken cross-allergy, which means he can't have anything—absolutely nothing—that contains chicken, and that includes the new recipe with chicken meat meal. It's already hard enough for him to find suitable food or treats, and now, once again, something he's used to has been changed.
