Do not feed chicken liver to cats under 4 months old. Cats under 4 months old can be fed 1 piece at a time, and adult cats can be fed 1-2 pieces at a time, once a week. Animal offal is very nourishing for cats, but they should not be eaten too much. Eating too much or eating it for a long time will cause obesity in cats and induce many diseases of the body's internal organs. Breeders can feed cats chicken, beef, fish, etc. to supplement nutrition.
