One of the most popular walnut cat litters is Naturally Fresh Cat Litter. This walnut-based quick-clumping kitty litter is available on Amazon for $20 per 26-pound bag.
Cat parents raved about the neutral, slightly nutty smell and lack of dust. Many reviewers also mentioned that a little bit of this litter goes a long way, saying that it was “more economical in the long run and less waste entering the trash/landfills.” If you’re looking for a low-odor natural option that’s great for the environment and your cat, it could be worth making the switch to walnut litter.
