hardwood floors? I'm so glad that I only have laminate in our house... fleas are NOT FUN! I would steam clean the rugs every couple weeks and be really persistent with vacuuming every surface they could lay their eggs in (upholstery, bedding, etc.) Even if your cat doesn't come in contact with it, YOU can carry the eggs around to different parts of the house without knowing about it. Bleck! *heebie jeebies* lol!
