A baby rat is not called a rat until it is a couple of weeks old. It has a gestation period of 19 to 23 days. Baby rats are also called pups or kittens. Baby rats can be male or female, and their ages range from a couple of weeks to a few months.
Baby rats don’t make much noise at first, just squeaks. But as they get older, they’ll start making hissing and chirping sounds. These sounds will mostly be ultrasonic, meaning they are not picked up by humans. Baby rats will live with their mothers for up to six weeks. Eventually, they will be weaned from their mother.
At five weeks of age, the baby rat will leave the nest and start to grow. Its tail will grow along with its body. By the time it is three months old, it will have a tail as long as its body. Its eyeballs will have developed by this time, but it is still a few weeks away from full development.
The baby rat will need milk for the first two weeks of life. If the mother is not available, it can be raised with formula. However, the infant rat will need regular feedings until it reaches weaning age. Once it reaches this stage, it can start eating solid foods. Rat food is usually a mixture of yoghurt, ripe banana, and the mother’s usual rat pellets. A moist cloth should be used to rub the belly of the baby rat. This will help in digestion and peeing.
