It is FAR from Dust Free

I’ve been using Fresh Step for years and whatever they have done is awful!!! There is so much dust that I’ve had to breath in cleaning the litter box is crazy, not the best for someone with breathing problems. I’ve tried to get in touch with them and they have never replied.

Extreme Fresh Step - Dust Free

This product is a very strong clumper. It as dust free as you can get the product. I have three cats using 2-3 cat litter pans (one bathroom temporarily out of commission) so I need things as easy as possible. The only negative is that you have to have a good litter pan scooper and it has to be cleaned more as any of the extra clumping power comes with some additional sticking to the scoop as well.

Omg the dust is so bad

Since fresh step decided to NEW & IMPROVE my original litter I had to try new litter. The dust from this litter is SO BAD, you can actually see the plume of dust as you scoop, and the perfume they add is not pleasant. I want my unscented dust free litter back. I have 11 cats and I go thru so much litter on a daily basis I just can not find a fresh step litter I like anymore.

Not what I expected

I normally order Fresh step extreme 4 pack love the product . Unfortunately chewy was out of stock so I had to get this instead I live in a rual area so I had to have something. This Advance extreme just doesn’t hold up like the Regular Extreme. Will do as a back up but had to order my regular from another store and dump everything soon as it came. Doesn’t hold off smells as long and I clean the box every day 1 cat.

Will not buy again

I have used FS crystals for years, but decided the urine odor and the speed in which my cats went through it was enough to look at other litters. I’m definitely sold on FS as a quality brand. However, I will not buy this litter in particular again, even if it’s the only litter on the shelves. In looking for a new litter, I’m looking at how long it lasts, odors, tracking, and dust. As an asthmatic, the scent of the litter is overwhelming and I see no sign of 99.9% dust free. From the moment I dumped the litter into the litter box, there was a cloud of dust. When my cats dig in it, a puff of dust comes up. Even when I scoop the litter, there is dust (after 6 days of use). The dust is the ultimate dealbreaker for me.

Clumping in my cat's throat?

Lately my cat has had difficulty swallowing and I am wondering if when he cleans his paws he is getting this litter in his throar? Has anyone else had this problem?

Superior Litter

I have tried them all through the years. If you like clumping litter, this is the best!! Great on odor and low dust too!

NOT dust free

The claim of 99.99% dust free is a joke. I get less dust from my orbital sander.
