I love both cats and dogs, but cats are more independent and "gentle", compared to dogs.
I have had quite a few, and as long as you feed them (ours live outside, so we don't need a litter box), they'll make great companions. Of course cats love to sleep, so they won't make to much noise. Cats are also some weird little critters. They like to sleep in the oddest positions/places, and they seem to do the strangest things.
Really hate it when people take about abusing cats, though. I've had a few gun owners tell me how they use cats as "target practice." That's about the time I cease conversation, before someone gets a fist to the face.
