Which is the best non-clay, natural, clumping kitty litter for automatic cat boxes?

And another reader reports that Litter Pearls are “VERY DANGEROUS FOR KITTENS! Killed 3 in one litter in Rancho Cucamonga. Also, silica presents an inhalation hazard to humans and pets.

I haven't tried this litter. A clumping litter made from organic materials. I haven't tried it, nor have I found out much about it.

"I have been using Smart Litter "Organic 'n' Safe." It is the best organic clumping kitty litter I have ever had (and I have had cats for the past 24 years!)! It clumps like clay, and with NO silica dust.

All of it is biodegradable so it can be flushed even if you have a septic tank. It doesn't stink like ammonia. It is a bit dusty; however it's actually a lot less dusty than any clay litter.

I highly recommend that you at least try this brand. Smart Litter makes different types of kitty litter which might accomodate you best but I find that The Organic 'n' Safe is the best for my cats. It is pricey ($16-18 for 17lbs.), but it's not as expensive as The Worlds Best - or at least where I shop.

So try it out if you get the chance. The manufacturer assures me that there is no bentonite in this product. I haven't tried this litter; I've only just heard about it.

If I have a chance to try it, I'll post the results here. From the company's Web site: "a multi-use product made from all natural pine...an excellent bedding and litter material for small animals, birds and reptiles. ... environmentally friendly, contains no silica dust and will compost quickly.

Lone Star Pine Pellets are safe for pets. I just added this litter after finding their Web site. I haven't tried it yet.

If you have, please write and let me know what you think.
