I wish I had some tips to share - that sounds absolutely awful! If the cat is an indoor cat, that leaves only two options. Either the source of the fleas is somewhere in the house, or the dog is bringing them inside and sharing. (How kind of the dog!)
My course of action would be to treat everything as if it were flea infested. I would start by cleaning EVERYTHING indoors. Shampoo the carpets and rugs, mop the floors, clean the upholstery, wash all the linens. I would also go ahead and dust and clean everything. I know that fleas aren't likely to live on the bottom shelf of my bookshelf, but I think it would give me peace of mind to know that I had cleaned it anyway. Next up would be to treat everything outdoors. I know that sounds like a total pain, but I can't think of another way to do it! As far as I know, no one has invented a flea detector. That might be a million dollar idea for your sister, though!
