Tofu litter is plant-fibre based, clumps and can be flushed, carries less dust and weighs little. Bentonite clumps tightly, locks in odour well and feels close to natural soil underfoot, which is why it remains the most widely used type.

Tofu suits flats, dust-sensitive households and owners who want a simpler cleanup routine. Bentonite suits homes that prioritise clump strength and odour control, and it is the common choice in multi-cat settings where waste volume is higher.

The trade-off is weight and tracking: tofu is light and travels on paws, and larger pellets may not suit every cat. Bentonite is heavy and dusty, so watch airways and floor cleaning. Flushing depends on plumbing, and older buildings or septic systems are unsuitable.

Let the cat's acceptance lead: switch gradually by mixing, and watch urination and stool. Frequent litter box visits or changed urine volume need veterinary confirmation; litter choice cannot substitute for a urinary check, and a cat avoiding the box after a switch is telling you something.
