I've got a foolproof method to rid your house of fleas, but you have to repeat it if you get another infestation, so go ahead and treat the cats in the mean time.
Fleas are attracted to light, so put nightlights in all your outlets that are close to the floor. (Remove the shields). Then place a shallow bowl of water right under each nightlight, and add one drop of any kind of soap (to break the surface water tension) so the fleas will slip under the water and drown. Move big objects out of the way, so that the lights can shine into as much of the room as possible. Make sure it's dark at night, except for the nightlights. Fleas will hop to your lights and jump at them, falling into the water and drowning.
It's actually fun the first couple of days to see how many fleas you get. When you aren't getting any more, you can stop and put your night lights away for next time!
