Daily care routine · Updated August 9, 2026

Scoop a traditional clumping litter box at least once every day, add clean litter as needed, and wash the box on a schedule that keeps it dry and odor-free. Cat Friendly Homes recommends washing with soap and hot water every one to four weeks; follow the litter and box instructions and clean more often in multi-cat homes.

The short answer

Daily: remove feces and clumps, check litter depth, and look for unusual changes. Every 1–4 weeks: empty and wash a traditional box with mild soap and hot water, then dry it fully. Automatic box: inspect it daily, empty the drawer as needed, wipe or wash allowed parts, and follow the exact deep-clean schedule in the manual.

Why daily checking still matters

A clean surface is more inviting to many cats. Daily scooping also gives you a chance to notice changes in amount, frequency, consistency, or color. An automatic box can hide those changes inside a drawer, so convenience should not eliminate observation.

Straining, repeated unsuccessful trips, crying, blood, or sudden house soiling may be medical warning signs. Contact a veterinarian promptly instead of waiting for the next deep clean.

How to wash a traditional box

  1. Remove all litter and dispose of it according to local rules.
  2. Wash the empty box with mild soap and hot water.
  3. Avoid strong fragrances and ammonia-based cleaners.
  4. Rinse and dry the box completely.
  5. Refill with the litter type and depth your cat accepts.
  6. Clean the scoop and surrounding mat as well.

How cleaning changes with two or more cats

More cats mean more waste and faster odor buildup. Scoop at least daily and increase the frequency when any box becomes visibly soiled between checks. Do not expect one frequently cycling machine to solve competition for a physical location.

Automatic boxes need manual maintenance

Check the waste drawer before it overfills, keep sensors clear, use only approved litter, and clean moving or removable parts exactly as the manufacturer describes. Unplug the unit before cleaning when the manual instructs it. Never hose down electronics or add a cleaner that can damage sensors, plastics, or a cat’s respiratory comfort.
