PrettyLitter is the strongest all-around pick in this comparison for health monitoring and lightweight convenience.
A crystal litter built around health monitoring and light weight, with a strong subscription convenience angle and weaker clumping value.
A grocery-store staple with broad availability, lots of variants, and okay overall performance without excelling anywhere specific.
Tidy Cats is the cheapest easy way to keep a box going. PrettyLitter costs about twice as much per day. It earns that only if the health signal is what you are shopping for.

| Cost across a yearThat daily cost carried over a full year of use. Lower is better. | $292 | $142better | $150 |
Neither run recorded granules outside the box, ammonia after one day and ammonia after three days, so those rows are left out rather than filled in from a similar bag. The full test data shows every reading we have.
