Miao Xiao Xia is a pet food brand, which mainly produces and sells cat food supplements. Complementary food refers to the food for the baby to gradually transition between meals, usually soft and digestible food. Regarding the level of meow and young Xia's complementary food, it is divided into the following levels:

1. Low-grade complementary food: Low-grade complementary food is usually made of ordinary cat food and has a lower price. Although it does not contain artificial additives, its protein content may be relatively low and its taste may be rough.

2. Mid-range complementary food: Compared with low-grade complementary food, mid-range complementary food pays more attention to the nutritional ratio and production technology of food. Common mid-range complementary foods may add some natural ingredients such as glycerin or bonito, which can increase the appetite and nutrition intake of cats.

3. Advanced complementary food: Advanced complementary food refers to the use of selected high-quality ingredients, usually adding more meat and vegetables, and may also contain additives beneficial to cat hair and digestive system. Cats may be easier to digest and absorb after eating advanced complementary food, and the gloss of fur may be better.
