A young rabbit is called a “kit”. They are born blind and furless and they are totally dependent on their mother. When they are very young the baby will only leave their nest if there is a problem. At two weeks of age, the young rabbits begin to eat vegetation, at four to five weeks old they feed alongside their mother. A young hare is called a leveret (up to one year of age). They are born with their eyes open and are left alone during the day, laying in place, in forms to avoid attracting predators.
