In fact, cats don't like fish the most. It can be said that cats prefer to eat high-protein mammals, such as mice, chickens, ducks, rabbits, insects and so on. Tracing back to the survival history of cats, cats are desert animals, and basically have no contact with marine animals. Cats are meat eaters, and the fish with strong smell is easily accepted by cats. So it's normal for your cat to like fish, and it's normal for her not to like fish.
