Flushable cat litter is usually made from plant-based or water-dispersible materials instead of conventional clay or silica. Even with flushable litter, plumbing systems, septic systems, local wastewater rules, and clump size can affect whether flushing is appropriate. When in doubt, disposing of used litter in the trash is the safer option.
These seven picks cover tofu, corn, pea husk, wheat, and other natural formulas with different approaches to clumping, tracking, dust, and odor control.
Top 7 Picks
1. PETKIT Mixed Cat Litter — Water-Dissolvable Tofu and Bentonite Blend
PETKIT combines tofu and bentonite in a fast-clumping formula. It is flushable and focuses on absorbency, low tracking, and low dust.
The mixed texture can feel more familiar to cats transitioning away from traditional mineral litter while still offering some of the handling advantages of tofu-based formulas.

Pros

- Water-dissolvable formula
- Tofu and bentonite blend

- Low-tracking design
Cons
- Contains bentonite rather than being completely plant based
