Open, covered and self-cleaning litter boxes sized for cats of different ages and sizes.
Cat litter box selection depends on the cat's size, age and preference for privacy. A covered litter box reduces odor spread and gives cats privacy, but some cats refuse to use a covered box because they feel trapped inside. An uncovered box is easier for kittens and senior cats to enter and exit without climbing over a high threshold. A self-cleaning litter box (LitterMaid, Litter-Robot) rakes or rotates used litter into a sealed compartment automatically after each use, reducing daily scooping to a weekly waste drawer disposal. Box size should allow the cat to turn around and dig comfortably; a box that is too small causes cats to eliminate outside the box. This section covers litter boxes by size, cover type, self-cleaning mechanism and odor control design.

Cat litter boxes are evaluated by size (small for one cat vs large for multiple cats), covered vs open top design (covered reduces scatter and odor escape vs open is easier for senior cats to enter), entry style (top-entry reduces tracking vs front-entry), depth of litter tray (higher sides reduce scatter), ease of scooping, odor containment design and price.
