I have tried all the Premium Brands I could get my hands on and I was not happy with the odour control of any of them. Even with the most expensive litters (including World's Best), I find that the box starts to smell after about a week and I have to change it after 2 weeks. I have tried regular store brand litter, Nature's Miracle Odor Control (has a strong pine cleaner scent), Feline Pine Scoopable (clumps break up), Dr. Elsey's Cat attract (no odour control), Clump N Flush (similar to Nature's Miracle) and the Arm and Hammer one (the baking soda tracks) etc. I have accepted the fact that cat urine and poo will smell but it's worth it because my baby gives me so much love. What I like about Worlds best is that it is much safer and it is flushable (which makes a big difference in keeping the odour down in your home). It has a corn scent but it's not too strong. It clumps well too. After my three months of trying all kinds of litters, I've decided to settle for World's Best.
