My cats hated this litter. It wasn't small enough for them to get used too and it didn't clump at all. The smell of poop lingered and urine just remained on the bottom of the box.

Pros: scent

Cons: doesn't work

I tried this when it first came out! I hate it! It smells bad to begin with and my cats looked at me like I was crazy. After they did decide to use it, it smelled even worse. Stay way for this product!

Pros: It stinks!

Cons: expensive

We tried this litter for our store cat, where odor is definitely an issue.

It does work all right for the first few days, and the poo is easy to scoop out. But after you stir it up, the urine doesn't really keep "soaking in" so pretty soon the box looks like it's full of sticky yellow rocks!

Our cat is diabetic, so maybe she pees more than a fully healthy cat, but there's no way we could afford to switch out the crystals as often as was needed. Even for a healthy cat though, I doubt the bag would last for a full month.

Pros: worked ok, but not great

Cons: VERY expensive

For all the good these crystals did me, I could have just filled my cats' litter box with small pebbles and called it good. This litter was completely ineffective and absorbed nothing. I only have two cats and one large litter box, but their urine just pooled at the bottom of the box. My apartment smelled terrible, as if my cats had been marking all day while I was at work. Avoid this stuff!

Pros: Well, it's not clay litter

Cons: Everything else

We used this litter in our cat playroom that has 10 cats in it. It worked great for the smell of the litter boxes but it got too expensive for our budget to keep buying it.

Pros: worked great with multiple cats

Cons: expensive
