The Elves Mixed Cat litter is the best product for your indoor adult cats.
Mixed tofu and bentonite cat litter combines the natural, biodegradable, and gentle nature of tofu with the strong clumping and odor-control capabilities of bentonite clay. At Elves, we added deodorisers to make the odor-control even better. 
Here's a more detailed breakdown:
Tofu Litter Advantages:
Natural and Biodegradable: Tofu litter is made from plant-based materials, making it a more environmentally friendly option. 
Gentle on Paws: The softer texture of tofu litter can be gentler on a cat's paws compared to some clay litters. 
Flushable (in small quantities): Some tofu litters are designed to be flushable, offering a convenient disposal option. 
Bentonite Litter Advantages:
Strong Clumping: Bentonite clay has excellent clumping properties, allowing for easy scooping and waste removal. 
Effective Odor Control: Bentonite clay absorbs moisture and traps odors, helping to keep the litter box fresh. 
Why Mix Them?
Synergistic Benefits: Combining tofu and bentonite aims to leverage the strengths of both materials, creating a cat litter that is both environmentally friendly and effective at clumping and odor control. 
Improved Performance: The bentonite clay fills in the gaps between the tofu pellets, enhancing clumping and absorption. 
Dust Reduction: Some mixed litters claim to reduce dust compared to pure bentonite litters.
Extra Odor Control: With the extra add in deodorisers, it makes the litter box odor free.
