What litter works in a sifting litter box?

Sifting boxes work best with clumping clay or a clumping natural litter that forms firm balls, since the slots only catch what holds together. Fine litters pass through cleanly, while large pellets and crystals can jam the slots or stay on top with the waste. Keep the litter about 2 to 3 inches deep so clumps form above the tray floor, and rinse the trays every few weeks so wet litter does not cake in the slots.

Should I measure before I buy?

Yes. Measure first and compare your numbers with the size chart on the product page, since sizing varies by brand.
