@Scrbblchick -- Sounds disgusting. I've never used a flea fogger either, but I have been tempted. I do use a flea spray on the furniture, and inside my vacuum cleaner, and that does seem to help.
Like you, I'm not sure I'd want to deal with all the prep work, and then the cleaning you have to do when you use a fogger of any kind. It sounds like a lot of work for results that may or may not be worth the effort.
I guess putting up with a certain number of fleas is just part and parcel of having pets, even when they're inside pets.
