You should scoop your cat’s litter at least once a day and do a full litter change and box clean about once a week , adjusting based on litter type and how many cats you have.

Quick Scoop

General rule of thumb

  • Scoop clumps and poop: 1–2 times daily to keep odor and bacteria down and encourage your cat to keep using the box.
  • Full litter change: about every 1–2 weeks for most clumping litters, more often for non‑clumping.
  • Box wash: monthly with mild soap and water for standard boxes (more often if there’s strong odor or accidents).

By litter type

  • Clumping clay: scoop daily, change completely every 1–2 weeks.
  • Non‑clumping clay: scoop daily, change every 2–7 days because urine isn’t trapped in clumps.
  • Silica/crystal: scoop solids daily, stir litter, change every 3–4 weeks if odor is under control.
  • Paper/wood or plant‑based pellets: scoop daily, full change about once a week to every 10–14 days , depending on saturation and smell.

Factors that mean “change it more often”

  • More than one cat using the same box.
  • Small box or very deep urine smell (ammonia) when you walk past.
  • A cat with diarrhea, urinary issues, or older/sick cats whose urine smells stronger.

A simple way to think about it:

If you can smell the box when you enter the room, your cat has been smelling it much longer—time to scoop or dump it.

Forum-style “real life” patterns

On cat forums, many owners report:

  • Scooping once or twice daily as the norm.
  • Dumping clumping litter every 2–4 weeks if they scoop consistently and don’t notice odor.
  • Doing a full scrub only every few months if there’s no illness, just using warm water so the box doesn’t lose all familiar scent.

Quick mini-checklist

Ask yourself:

  1. Do I scoop at least once a day?
  2. Has it been more than 1–2 weeks (clumping) or 2–7 days (non‑clumping) since I fully changed it?
  3. Do I smell ammonia or see wet patches stuck to the bottom?
  4. Is my cat suddenly avoiding the box?

If the answer to 2–4 is “yes,” it’s time to change the litter now. Bottom note: Information gathered from public forums or data available on the internet and portrayed here.
