You should have included another option, for those of us who have multiple cats.

I also have three dogs, so whatever hairs the cats leave are quickly eclipsed by the hair of three large, shaggy dogs.

So yeah, we vacuum a lot, and the carpet cleaner comes in handy. Hairs don't bother me - I shed more (as a human with long hair) than my animals. I keep telling people, no one ever died from hair.
