If you find young kittens, please do not assume the mother has abandonned them. Mother cats move their kittens when they are about 10 days old. Since she can only carry one at a time, she has to leave the others behind. If the little kittens are quiet, please leave them for at least 12 hours to give their mother time to go back and forth. You will know if the kittens are in distress as they will be screaming with hunger. Please let nature do its work.
