How Often to Change Cat Litter for One Cat

Scoop every day, and completely dump and refill clumping litter every 2–3 weeks. For non-clumping litter, replace it all every 3–5 days. Wash the box with mild soap each time you change it.

The routine for one cat

• Daily: scoop solids and clumps.
• Weekly: top up with fresh litter.
• Every 2–3 weeks: empty, wash the box, and refill.

Signs you're changing too rarely

• Your cat avoids the box or goes right outside it.
• A persistent ammonia smell even after scooping.
• Litter is damp or clumping poorly.

FAQ

Q: Can I just keep adding litter instead of changing it?
A: No — old litter holds odor and bacteria. A full change is essential.

Q: Does clumping litter last longer than non-clumping?
A: Yes — clumping litter can go 2–3 weeks; non-clumping needs replacing every few days.

Q: What soap should I use to wash the litter box?
A: Unscented mild dish soap and hot water. Avoid strong cleaners and bleach.
