While you cat probably spends most of the day sleeping, she also spends lots of it looking for mental stimulation. If you have multiple cats, they can keep each other occupied by playing together. Single cats, especially single kittens, are much more likely to knock things off shelves and dressers, climb the blinds, bother the plants, explore (and chew on!) cords, and generally engage in naughty kitty behavior, even if given toys.

Having multiple cats is also a great way to keep your cat from being lonely. Even if the cats don't play together, they will still be keeping each other company. Many cats will snuggle with each other, or at least sleep in the same room. Just like humans a cat may not want attention or company all the time, but will be content knowing there is a companion near by.
If you are worried that caring for multiple cats is more work or more expense relax. Caring for two cats is just as easy as caring for one. You put down two dishes of food instead of one, and have slightly more waste matter to remove from your litter box. You will buy slightly more food and litter than for a single cat, but not a substantial amount.
If you are certain you only want a single cat, talk to the shelter you are adopting from, they are certain to have a few cats who prefer to be single cats. A single kitten is not a good idea, and most shelters or rescue groups will only adopt kittens out in pairs.
