As obligate carnivores, cats need to consume sufficient protein daily to ensure their basic nutritional needs are met. Therefore, crude protein content is an important criterion for judging the quality of cat food. A qualified cat food ingredient list should meet the following requirements:

Crude protein: The higher the content, the better; if it is below 32%, it will break down your own muscle.
Crude fat: with a content between 14% and 20%, provides essential fatty acids and promotes healthy fur and skin.
Crude fiber: The content is between 1% and 8%, which helps with intestinal peristalsis and hairball expulsion.
Taurine: at least 0.2%, essential for a cat's vision and heart function.
Calcium-to-phosphorus ratio: should be between 1:1 and 2:1 to ensure healthy bone and teeth development.
In addition, the source of ingredients for cat food should be clear and safe and compliant.
