LitterFresh ProBiotic Deodorizer Spray

I have tried other litter box deodorizers and probiotic cleaners. One spray made the litter too wet (I admit being heavy handed with spray) - not good for corn based litter. The other is a can of small kernels of fragranted deodorizer you shake over the litter. It was like putting fragrance over funk (kinda helped, but still pungent). Had to use baking soda as desparate for something but couldn't use a lot - not good for cats. It did nothing. This product really destroys the smell left on the litter after removing solids. It cleans the litter. I am fastidious in cleaning the litter box but there is a smell in the litter after two or four uses. I was always concerned over the remaining toxic substances left behind. I ran out this product and, believe me, I could tell the difference. It was a battle to remove odor. I use a mix of World's Best corn base cat and Naturally Fresh walnut cat litters. I used to use Nonscents cat litter as I could tell it had hydrochlorous acid in it, but was not cost effective, put dust and residue on my cat's paws, and could get gummy. I also use actvated charcoal cat litter additive (which also ran out). I had used a zeolite based product advertised as a deodorizer - do not waste your money. The only thing it did was leave residue on my cat's paws and cleaned up like clay litter for particles outside the box. Activated charcoal does help with odor but up to a point - it doesn't clean. With this spray, in a small space, after my cat uses the litter box, I spray this in the air and it immediately kills odor. After not having this spray for three days, I can attest to the difference. Today, I sprayed, he used the litter box, and I only smell the walnut of the litter. Get this!
