Flea bitesReader submitted

My little fella is a magnet for fleas, we have a cat and two dogs and the other three members of the family never have a bite, let alone see a flea. I'm reluctant to use a bomb as I don't like the chemicals in the house, but once he was so badly bitten, I thought he was getting chicken pox! So any natural ideas to use on him that would stop them would be muchly appreciated.
