To reduce cat litter tracking, check where the grains land. Place a mat across the exit path and check that your cat has room to turn and dig. Try one change at a time before replacing the litter.

Same mess. Different causes.
Sweep once. After normal use, see which pattern looks familiar.
A trail from the exit
Check where your cat steps or lands. Does that path cross the mat?
A pile beside the box
Look for litter kicked out while digging. Check the fill instructions and usable space.
A fine coating nearby
Check dust during pouring or scooping. Low dust does not automatically mean low tracking.
Three changes to try.
One at a time.

Move the mat onto the exit path.
Keep the entrance clear. If your cat avoids the mat, try another position or surface.
Check room to turn and dig.
Look at usable interior space. Higher sides still need an entrance your cat can use comfortably.
Follow the litter’s fill instructions.
If you change litter, start with a manageable quantity. Keep the box and location familiar.
Before buying a new box or litter
A covered or top-entry box is not a guaranteed fix. Check how your cat enters, exits and uses it, plus how easily you can clean it.
Compare the actual litter’s texture, your cat’s acceptance and the mess left behind. Material labels alone do not predict tracking. Follow the product’s filling and maintenance instructions; there is no single depth for every setup.
