Momma Cat and 4 kitties have fleas really bad, how do I get rid of them?

My cats are covered with fleas, is there any way I can get rid of them while their still little?

Bathe the kittens with regular Dawn dish washing liquid -  the blue stuff.  It doesn't kill the fleas but weighs them down in the water so they drown..  Treat mommy with Revolution, although if you can bathe her, do it.  You can also buy Capstar and give some to mommy.  If the kittens weigh more than 4 pounds, you can use Revolution on them.  You get the at the vet's.
