The weight of a kitten is related to its age. Generally, a kitten grows one pound in one month. If the kitten is in good health and has balanced nutrition, the weight will be relatively heavier. If the kitten is frail and sick and has a poor appetite, then the kitten will weigh more. Weight loss occurs and lifespan is significantly shortened. Once a kitten is found to be unwell, it is necessary to take the cat to the pet hospital for examination and treatment in a timely manner. During this period, the cat should be supplemented with nutrients to promote the healthy growth of the kitten.
