Cats cannot eat raw oysters. Although oysters are rich in protein, oysters live on the seabed for a long time and carry a large number of bacteria. Cats will be infected with parasites after eating them. In addition, oysters themselves are high in salt. If eaten for a long time, cats will increase their risk of death. The burden on the gastrointestinal tract affects the cat's health. It is best to eat cat food as the main food to prevent the cat from being picky eaters.
