I Love this:
Cat Attract Litter - Precious Cat Litters - Quality Cat Litter (http://www.preciouscat.com/attract-litter-p-5.html - broken link)
99.9% dust free (have a kitty with asthma)
I have 2 kitties...
and 4 boxes, and I still scoop everyday, once in while every other day.
and...
I really, well, can't even remember when i have changed/threw away, the remaining litter.
stays clean, less fuss.
even if I wash the box itself, sometimes i still keep the litter as it is not really dirty, just pour in another box, still use it.
would get a 2nd box.
2 boxes for one kitty, I would do that.
boxes in good location ... For the Kitty, quite as possible, and a peaceful non "trapped" location.
so, even if you were concerned with $ (don't even really know the price of this, just know that it works, so, thats what I go and get, easy as that, plus cats do Not like change!)
then this I think would be all the better price wise too, as I said, I rarely have to change the remaining contents, lasts forever!
With four or even 2 boxes, who wants to spend time "box changing" once a week or even 2 times a month.
don't know if i ever did that hah! and my kitties are 7! and in the past had used and tried different kinds of litter.
Oh, actually, I think that I had to with that Wheat litter, it was the worst!!! smelt like ammonia, bad in 1 days time, and it would stick to the bottom of the bottom of the box, so I had to change it then, but it was horrible, it didn't last in my house long and I return the partly used bag back to the store.
ok, so sorry for the story...
Bottom line....
try it!!! this litter--- works great!!!
added plus: Kitties like the smell... and its Natural and still Clumping!!!
hate the other ones with so much dust and odor.
tried the Corn... it think-- Worlds Best Litter... no good, wanted it to be.
tried the Wheat... SWheat... no good.
Hope this helps and doesn't confuse ya!!! hah!
