Kittens usually refer to cats from birth to about 12 months old. 0-2 weeks is the newborn period, 2-8 weeks is the exploration and weaning stage, 2-6 months is the rapid growth stage, and 6-12 months gradually approaches adulthood. Different breeds mature at different times, and large cats may take longer.

There are obvious differences between kittens and adult cats in terms of nutritional needs, digestive and immune development, and environmental tolerance. Kittens need a high-nutrient-dense diet, regular meal sharing, and a safe and stable care environment.

主要包括新生期、哺乳期、断奶期、快速成长阶段和青少年阶段。每个阶段对营养、环境和护理的需求不同。

断奶后至约6月龄通常是幼猫生长较快的阶段，需要完整均衡的成长配方，并持续记录体重、食量、粪便和精神状态。
