The difference between the blue label and green label of Bailey's cat food mainly lies in its ingredients and applicable objects. Blue label cat food is suitable for adult cats, while green label cat food is suitable for kittens and adult cats.

The ingredients of Blue Label cat food are more suitable for adult cats, containing more protein and fat to meet the energy needs of adult cats. Also, Blue Label cat food is fortified with nutrients that adult cats need, such as probiotics and joint-protecting ingredients that help maintain their health.

Green Label cat food, on the other hand, is more suitable for both kittens and adult cats, as it has a more balanced composition that includes the right amount of protein, fat and carbohydrates to meet the growth and activity needs of both kittens and adult cats. In addition, Green Label Cat Food is fortified with nutrients needed by kittens, such as DHA and Omega-3 fatty acids, which aid in brain and vision development.
