Glad you asked.
I am VERY particular about litter, so are my girls. I want no perfumes, chemicals, only the "healthiest" I can find for my girls. I think I have tried them all. Didn't like "World's Best", anything when corn, wheat, etc. attracts bugs and ants, can get moldy.
Used Dr Elsley's for years. Never really liked the fact it stuck to the box and was like freakin' cement. Always worried about the girls licking it off their feet and fur. But I couldnt find anything else really that passed my scrutiny..lol.
About 2 months ago I switched to a new litter, and it is FANTASTIC! I can't believe I am this excited about a litter, but I am. BTW, I know this is going to sound like a commercial, but I do not work for the company or anything, I just really love this litter.
It's called
BoxieCat. It's only available online @

It's hand's down the best litter I have used. It's clay, finely ground so it clumps, but without the clumping agents. It's so clean, the clumps stay on top, nothing sticks. It's pricey, partially because it's delivered, not available at retail stores yet. But a bag lasts a long time (normal size box, only a bag a month). You don't' have to scrub the box as often, kitties love it. It's unscented, all natural,
forms smaller and lighter clumps, and 99.9% dust free. It's made in the USA and was Cat Fancy's 2012 "Best Product of the Year".
I loved it so much I got a bag for my Mom and when I asked her how she liked it, the first word's out of her mouth were "It's so CLEAN!". She is hooked too. Try one bag, I think you will feel the same way.

Like I said, it's kind of pricey, they ship it in a flat rate Priority Mail box, and I know even at a commercial discount, they are paying over $10 just to ship it, so they really aren't making a lot of money on this. I am encouraging all my friends with cats to try this stuff, cuz I want the company to thrive and grow, I dont ever want to be without it!

Plus it's a family owned and operated company that supports shelters and rescues.
