On the fourth day of life

Baby hamsters will continue to develop and grow. They will begin to open their eyes and begin to move more actively around their nest. During this period, they will need more food intake, as their bodies are actively building new tissues and organs.

The mother hamster will continue to provide milk for her children, but if you are raising baby hamsters independently, be sure to provide special formula for baby hamsters or milk adapted for other small animals. Also, make sure the environment around the nest is kept warm and dry to keep the baby hamsters comfortable.

Baby hamsters on the fourth day are generally still very susceptible to infection and disease. So, if you are concerned about the health of your baby hamster, it is better to consult a veterinarian or hamster expert for proper advice and treatment. Also, be sure not to disturb the nest or handle the baby hamsters too much, as doing so can cause stress and interfere with their growth and development.
