Rated 5 out of 5 by from Yes expensive but economical! Best cat litter that we have ever used. We run a not for profit cat rescue, Animal House in Colingwood Ontario and have converted to World's Best for all the cats....10 boxes. The litter is perfect for multi cat use and is so easy to clean. It lasts weeks longer than the traditional clay clumping litter so the higher expense is mitigated by the length of time it lasts. Bonus....great odor you can imagine with so many cats a real problem.

Rated 5 out of 5 by from Miaow--wwweee always choose World's Best! 2 cats, 3 litter boxes. I can;t afford to toss the " old" (very dusty) litter unused, but Roger and Clemmie refuse to use any box except the one in my study that has World's Best in it. Easy to get rid of, zero odor, it's worth the extra cost. Esp for Roger who has a chronic upper respiratory infection and can't deal with the dust.

Rated 5 out of 5 by from Is the BEST! Been buying World's Best for a few years now...tried other brands that were a bit cheaper & said they did the same thing but did NOT! I was left with bits of litter all over my house & those brands did not clump well either so I'm back with World's Best & sticking with them!

Rated 5 out of 5 by from Love, love, love! My three cats have been using World's Best for over a year. We switched from clay litter when our male cat was diagnosed with diabetes. The clay litter just did not soak up the extra urine. Switching was the best thing we could have done. There is no "cat odor" with World's Best, and my cats love the lavender fragrance. (We do too!).
