Good cat litter
Very good cat litter. The fragrance has bothered me so I have to get the unscented.

The only brand I will buy
After trying a handful of litters that promised freshness but delivered dust clouds and artificial scents, this one finally hit the mark. Even though it’s labeled “MultiCat,” it works beautifully for our solo feline—no overpowering fragrance, no mess, and no drama.It is Unscented but Powerful,, which is a win for sensitive noses (both human and feline). Yet it still neutralizes odors impressively thanks to the baking soda infusion.

Inconsistent product—often great.
I have purchased at least 30 of these. The reviews are inconsistent because the product is inconsistent. I ordered a group of 5 last time, and two of the five were heavily scented, so I’m a little concerned about ordering it again. Sometimes a box of it will have a lot of fine dust, but not often. When it’s good, it’s very good, which has been the majority of the time.

Clumps well. Not dusty. Does stick to cat's feet a bit.
Have been using arm & Hammer cat litter for a long time and prefer it over other brands. This version clumps well but will get quite hard If wet material remains in litter box too long. Also sticks to cat's feet more than I would like but not as bad as smaller grained cat litter. Not sure so-called odor killers are that effective but cat waste odors can very in intensity. Overall I am generally pleased with it.Like all cat litters, it is overpriced for what it is.

Soft, Unscented, and Truly Odor-Controlled
This is the only litter my cats approve of! It’s soft on their paws and doesn’t have that strong scent that usually deters them from using the litter box. I was worried at first that being unscented would mean dealing with odors, but the baking soda really does the job of neutralizing smells. I’ve tried other litters before, but nothing compares to this one. This is the only litter I’ll be purchasing from now on!

Stop with the fragrance!
This is good enough, but only when I open the box and there’s no fragrance. It’s supposed to be unscented but sometimes there’s a light but obvious perfumey or floral scent that activates my allergies. I wake up in the middle of the night because I can’t breathe after my cat uses the box. I’m always disappointed when I open the box and it stinks, but I have to use it because I need litter by the time it comes on Subscribe & Save, and it’s too heavy to return.When it comes actually unscented, it works well enough. I use it in my litter robot, and I have to extend cycling to at least 15 min after my cat uses it because it doesn’t clump right away. It will clump, but you have to give it some time, and even at 15 min, sometimes it will break apart in 2-3 pieces. But there’s absolutely no dust, which I’m super happy about (and so is my litter robot), and none of my cats sneeze or have any adverse reactions to it. I did have to slowly introduce my cats to it after switching from Tidy Cats Free & Clean (too much dust and broke my previous litter robot) as they didn’t take to it right away. As far as tracking, there’s some, as with all litter, but it seems to be contained to the litter area. It’s less tracking than my former litter option, and that’s a plus.
