How Often Should You Change Cat Litter? A UK Owner’s Guide

There is no single perfect schedule for changing cat litter. The right routine depends on how many cats you have, the tray size, the litter depth, the formula and where the tray sits in your home.

For most indoor cat owners, the practical approach is simple: scoop regularly, top up clean litter when needed and fully refresh the tray before it becomes unpleasant for your cat or your household.

Scoop daily where possible

Daily scooping is the main habit that keeps a litter tray manageable. Clumping litter makes this easier because used litter can be removed from the clean litter in scoopable clumps.

If your cat uses the tray heavily, or if you have more than one cat, you may need to scoop more than once a day. This is especially true in flats, bathrooms, hallways or other shared living spaces where tray smells are more noticeable.

Full tray changes depend on your setup

A full tray change means emptying the tray, cleaning it and refilling it with fresh litter. How often you need to do this depends on your cat’s habits, tray hygiene and how well the litter is performing between cleans.

Do not rely only on a fixed calendar. If the tray smells stale, clumps are breaking apart or your cat seems reluctant to use it, those are signs your routine may need adjusting.

Use enough litter depth

Too little litter can make clumping less effective. If the layer is too shallow, moisture may reach the tray base more quickly, making the tray harder to clean.

Use a sensible depth for your tray and keep it topped up after scooping. A consistent depth helps you compare formulas more fairly and makes daily maintenance easier.

How clumping litter helps the routine

Clumping litter is designed to separate used litter from clean litter. This can make daily scooping faster and help the tray stay fresher between full changes.

Start with a 5kg single box if you are testing PawPure

If you are trying PawPure for the first time, start with a 5kg Trial Pack single box. It contains 2 x 2.5kg bags, so it is a full-size starting point for testing texture, scent profile, clumping and everyday tray maintenance at home.

You can compare the 5kg Trial Pack single box options before stocking up.

Move to bundles when you know your routine

Once you know which formula works for your cat, the 15kg Bundle & Save options are better for repeat buying. For households that use litter quickly, the larger long-term supply options can reduce how often you reorder.
