However, there are some situations where cats may have some adverse effects from eating fish. For example, if cats only eat fish and no other foods, they may be deficient in other important nutrients, such as vitamin A and taurine.

Therefore, when providing fish to cats, you should pay attention to the appropriate combination with other foods and ensure that the fish is processed and clean.
