Only the mother takes care of them. When the kittens are two months old, they don't need milk any more and can eat grown-up food. They stay with their mother until the fall. By then, they are half-grown and weigh about twelve pounds. They are ready to live on their own.
Bobcats live to be ten or twelve years old.
