Unless you train your cat to use the toilet, household litter boxes are an absolute must. Litter boxes can range from a simple plastic tub filled with litter to a high-end, automated box that is self-cleaning. Litter box deodorants, cat litter, and sometimes a little privy where the cat box can be hidden are sanitary tools that will be appreciated by cats and humans. Sifting litter boxes, a compromise between the plain box and the automated box, can make cleaning up after kitty a lot easier. Few people love litter boxes, but the alternative is less appealing.
