Why Unscented Wins

Cats have a far stronger sense of smell than humans, and heavily fragranced litter can be genuinely unpleasant enough to cause them to avoid the box entirely — leading to “inappropriate elimination” that’s really just a litter preference issue.

FAQ

How often should I change cat litter completely?+

For clumping litter, scoop daily and do a full change every 2-4 weeks depending on the number of cats and box count. Non-clumping litter needs full changes more frequently, every few days.

Why does my cat avoid the litter box sometimes?+

Common reasons include a dirty box, disliked litter type or scent, a box that's too small, or a medical issue — persistent avoidance is worth a vet check to rule out urinary problems.

Is clumping or non-clumping litter better?+

Clumping litter is generally easier to maintain since it isolates waste for easy daily scooping, which most cats and owners prefer.
