You should go to their site. Only their BFF line contains exclusively fish and even then they only use small sustainable types of fish that contain little to no heavy metals. A large amount of people on this website feed their "Paw Lickin' Chicken" flavor as well as other fowl flavors. It is literally just chicken and sometimes turkey! They also have beef and lamb options (all without fish in the ingredients). Weruva has been rated by many as pretty much one of top brands of wet cat food if not the top brand because they have such good ingredients and are such a responsible company. A lot of cats LOVE it too. It is very appetizing when you see it.There was something about the Weruva... If not vegetable, then fish in some form. I did look it up.
