I don't know of any and don't see how it could be possible to spray a chemical that could kill fleas, yet still be cat safe.
I'd spot treat your cat, wash & steam everything, & thoroughly vacuum.
Diatomaceous earth sprinkled between sheet & mattress, baseboard cracks, windows, etc., may help. Essential oils are toxic to cats, so I'd be leery of any sprays containing essential oils.
I bought a "pet safe" flea spray from my vet one time. Even though all the animals were out of the room when I sprayed it, and didn't let them return for a while, one of my dogs actually got poisoned from it and I had to rush him to the vet. Most animals will not have a bad reaction to vet prescribed sprays, but there are always some that will get ill from them.
I use nothing but FOOD GRADE diatomaceous earth these days. Your pets can ingest it and it won't hurt them.
