Although I know that clay based cat litters are not the most healthiest products in the world, they tend to be the most economical.
I prefer Tidy Cats Scoop: Multiple Cats. This particular brand comes in three (3) different formulas: Immediate Odor Control (Blue Label), Long Lasting Odor Control (Red Label), and Anti-Bacteria (Green Label.) I ALWAYS purchase the 35 lbs (with 3 lbs. free) yellow buckets for a total of 38 lbs. for $9.99! Plus, I ALWAYS redeem the $1.00 dollar off any Tiny Cats product manufacturer's coupon with every purchase. Therefore, I end up paying $8.99 for a 38 lbs bucket of cat litter. Tidy Cats is economical and considered "middle-grade" cat litter. It is the lowest clay silica dust cat litter, scoopable, available in a variety of formulas, reasonably priced and you get more your money! Try getting that amount for that price with any other cat litter product. It won't happen and I have literally tried them ALL i.e. Fresh Step, Exquisi Cat: Scoop Premium Cat Litter Fresh Scent (a Petsmart brand), Litter Clean (a Sam's Club brand), Crystal Clear Litter Pearls (by: Harvest Ventures), Feline Pine, Arm & Hammer, Carefresh (paper pet bedding), Swheat Scoop and World's Best Cat Litter, just to name a few. The only two (2) products that I feel are better than Tidy Cats is of course Swheat Scoop and World's Best IF you can afford to pay their expensive price tags. Been using Tidy Cats for twenty-six (26) years now and never once did I ever have a problem with it. I love it and my kids absolutely will NOT use anything else!
