Tofu cat litter is made of food-grade soy fiber which is a natural option that is biodegradable and can be flushed down into the toilet. This cat litter works as an excellent liquid absorbent as it can take up moisture up to 3 times more compared to traditional clay litters. With an instant clumping formula, it clumps quickly upon in contact with fluid. Its fast absorption rate protects your cat and litter tray from toxic ammonia and odor.
