Okay, so I think we're going to use Advantage on our cats, who are infested, but our house is also flea-ridden. I got some powder to use on the carpet, but I need to know if it is safe to use the two in conjunction, or if it will overdose the cats on flea killer.... I am disgusted by the fleas in my house, and need to get rid of them asap, but I don't want to put myself, my cats or my baby at risk. TIA!

never mind! :)
