The problem: My cats have been using Fresh Step Extreme Odor Control Scoopable Cat Litter (scented or unscented) for a long, long, long time. The problem with that brand is the EXTREME dust problem that gets on everything inside the house due to the central air conditioning/heating system. And that problem has worsened over time as I have adopted more stray cats or cats that have lost their home. More cats using more cat litter boxes creates even more EXTREME dust problems. You can change out the central air filters all you want, but the dust is just too fine for the filters to catch all of that stuff. :(
The solution: Precious Cat Ultra Premium Clumping Cat Litter has solved the dust problem! I started switching over some cat litter boxes to Precious Cat Ultra Premium Clumping Cat Litter in December 2013 without any of my cat family objecting to the new cat litter. The dust problem is disappearing as my inventory of the other brand of cat litter is depleted. I am EXTREMELY pleased, and I am sure the cats are happier not having to breath the dust from the other brand. :)
I have read some reviews on Precious Cat Ultra Premium Clumping Cat Litter on this website that have suggested adding activated carbon to the cat litter to help with odor control. I second the suggestion, and have recently started adding a capful of Marineland Black Diamond Activated Carbon in the 40-ounce size container to a full bag of Precious Cat Ultra Premium Clumping Cat Litter. That seems to be about as much carbon that I see in the previous brand purchased, and the activated carbon is very effective in helping control slight odor over time that remains in the cat litter even after removal of clumped used litter.
It's nice when you're searching around on Amazon.com to see if there is a solution to a problem one is having. Precious Cat Ultra Premium Clumping Cat Litter has solved an EXTREME dust problem in my house. Another of life's problems solved.
