Sometimes I buy this and it works great. Other times, it's like regular non-clumping litter. When it work right, it's great. But other times, it won't clump and doesn't control odor at all. I don't know if it doesn't get mixed up well at the factory, or what the problem is.

We have bought this litter from Sam's for many years. It has always been a great value, and it is wonderful that it comes in a plastic bucket! It always worked very well...that's why we're so disappointed it seems it is no longer available! PLEASE bring it back!

Last batch I bought, came out of the container with a mighty cloud of dust. Purchased several containers earlier and had no where near the dust. Something has changed, either a new formula or a new supplier. Great price but the dust will kill you!!! Would have recommended highly before but not now.

This so-called new formula has a texture that looks an feel like dirt dust. It clumps and sticks to cat's hair and paws in effect gets carried to wherever the cat walks, sits or lays. The previous formulas did not have this effect. It turns basically into mud with the cat's urine.

I have 4 adult cats and use a lot of litter. I've tried this "Improved 4-in-1" to save money, but am clearly throwing money away with this product. IF clumping happens, it's usually too soft and quickly crumbles when lightly shaken in the scoop. Too often the litter is only moistened! And the odor control is non-existent. Dusty, too. In short, a waste of money; I'll be going back to pricier brands where I'll be using less and actually saving more! Only if Sam's reformulates and improves will I give it another try.

Is far from "scoopable". We used this because it was cheap, but smells horrible and basically have to replace entire pan each time the cat uses it. Spend a little more for the Fresh Step scoupable with Febreeze...HUGE difference! That stuff is amazing!!

I bought this product a month ago not realizing they switched the formula to "new improved 4 in1 control". We used the old 'Simply right' product for more than 5 years and it worked great. Now 'Member's mark' doesn't form clumps, not scoopable at all. I will have to change to the next in line product which is twice more expensive, but does the job. Why did they have to change?

To be fair we bought and tried using a whole bucket twice and it did not seem to be improved from the latter time of buying and using. In a nut shell it does nothing to eliminate odor and it is pretty dusty. It does clump the urine decently but that's the only plus about the product.

I have been trying to get this litter since March 2021. Seems they have discontinued it. So extremely disappointed in Sam's Club. My 2 cats love this brand & I do as well since it clumps nicely. Not a heavy perfume smell like others. Purchased Tidy Cats as a substitute & I as well as my cats absolutely hate it. It does not clump at all & when you try to scoop the pee spots it just breaks apart leaving it all in the litter box so we end up having to ladle it out.so the ammonia smell doesnt get too strong. I will never but Tidy Cats again! PLEASE BRING BACK MEMBER'S MARK CAT LITTER!

I bought this two weeks ago. I was excited about the price. We scoop every two days. It does an okay job of clumping, it is very dusty, and the odor control is non-existent. I came home today of my house smelling awful. It took me a while to track down the odor source and this is it. Tomorrow morning I'm going to get my old brand, and throw this stuff out.
