Cats can eat chicken liver occasionally, but it's not recommended to feed them large amounts. You can feed them a small piece about once a week, cooked and mashed, then mixed with their cat food.
While chicken liver does offer some nutritional value for cats, such as providing trace elements and iron, excessive consumption or long-term sole feeding may adversely affect a cat's health. Therefore, cat owners should exercise caution and avoid feeding chicken liver in excess or as the sole food source for extended periods. Chicken liver can be given as a supplement or occasionally, but it should not be a staple food for cats.
