It’s a common issue, but often manageable. Sticking primarily occurs when urine reaches the bottom before clumping, usually due to these key factors:
— Insufficient Depth: A shallow layer of litter (<5 cm) allows urine to pool at the bottom.
Solution: Maintain a thick layer of litter (at least 5-7 cm).

— Poor Litter Quality: Litter with slow absorption or weak clumping will penetrate deeper.
Solution: Choose high-quality, fast-clumping clay litter (often higher in sodium bentonite content).
— Rough Litter Box Surface: Textured boxes provide more surface area for wet litter to adhere to.
Solution: Use a smooth, slick plastic litter box.

— Infrequent Cleaning: Old, saturated litter at the bottom loses its clumping ability.
Solution: Scoop waste promptly and change the entire litter box regularly.

In summary, while some sticking can be normal, it can be significantly reduced by ensuring proper litter depth, selecting a quality product, and maintaining a consistent cleaning routine.
