I always bought the old one 3x odor control herbal essence, and it was great. Never any odor. This 4 in 1 Formula is the worst cat litter I ever bought. Changed the litter in the box Thrusday, on Friday the box and room smelled so bad even with no cat waste in it. This stuff needs to be discontinued and the old herbal essence put back in the stores. I have a litter box in the basement with the old 3x odor control herbal essence and it is great, no odors and everytime you scoop out the waste is smells as fresh as the first day you put it int the litter box. Members Mark 4 in 1 Formula is a waste of money. Have to buy another brand and clean out the litter box again after only 2 days.

When my wife and I were talking about switching our litter to Member's Mark I jokingly said, “We use their toilet paper... I'm sure the cats won't mind their litter!” They don't seem to mind it. But we do. It's an extremely dusty product. It's also a bit thicker than our previous brand which makes it a tad more difficult to scoop and sift. This is the one Sam's Club product I would stay away from. The cost savings is not worth the headache of cleaning/dusting more and coughing through scoops.

Absolutely the worst dusty litter I have ever used. It has made an absolute mess out of my utility room with dust on everything. I normally have a vacuum running above the litter box to suck up normal dust when I refill the litter box due to volume being generated but with this stuff I am surrounded in a cloud of dust just from scooping waste from the box twice a day. Would have given it negative overall rating if it was possible.

We've been using this kitty litter for years. It disappeared from the stores for a couple months, now it's back and you can keep it! Horrible! No clumping, smells - impossible to clean boxes! Cats are starting to misbehave to the point this "crap" is getting the boot to the curb.

For a little while now, the litter just doesn't work. It more or less just masses into on big, awful pile which, when you go to scoop, breaks up into small pieces that won't stick together. There's barely any odor control, and the thing is incredibly heavy but doesn't last the week. Total waste of money.

I was looking for my usual litter, and they didn?t have it. I bought this product, and was sorry. It is super dusty. Doesn?t clump well at all. Doesn?t contain odors well. I will not purchase or recommend this item at all. It needs to be reformulated.

I poured this in to the litter box and the cloud of dust that ensued was beyond belief. It made me cough - just imagine what it's like for the cats! It was like pouring a bag of cement into a cement mixer if you've ever done that before. After it initially settled,I stirred it around like I was a cat and dust billowed up more. Really bad for their lungs! Now I'm out 10 bucks. It does clump but it's not worth their health. I'd take a video but I don't have time.

I am a professional petsitter and have scooped a LOT of litter boxes. Maybe my expectations were low because "you get what you pay for", right? Well, this was certainly better than I expected from the price. I have two mostly indoor cats - and I am very bad about remembering to scoop the litter box. I have two boxes, but they both seem to prefer the box in the living room (of course), under the desk. When you walk in the front door, if the litter needs scooping, it's OBVIOUS. However, when this happens, I will go "oh no! It's been 4 or 5 days since I scooped the litter!" That's a long time for two cats in one box but I will admit I sprinkle a bit on a baking soda/essential oil mix to help with odor control. I also like the clumping factor of this brand. One of my cats will p** (it wouldn't let me use the real word - Really) in the corner of the box and it's very difficult to scoop there. With this litter, it seems to scoop easier than many other litters with a higher price tag. So, I find this product to be "very good" but short of the 5 star "excellent".

This is a terrible product that I am unable to return via the online chat or calling customer service. It is 42 pounds so difficult to bring in. I am worried that this is a dangerous product but customer service doesn't care—because of the smell that fills up the apartment even when there is a lid on it. Not only does it not clump. But it burns your eyes to be in the same room with it. And changing litter it's difficult to do and not vomit because of the litter smell. I see now why it was so cheap and the lid was on so tightly.

We've been using this litter for over 10 years with no complaints. Recently, however, the formulation has changed or quality control has been eliminated. Dust has become excessive. Clumping, which had been firm, has almost disappeared. Clumps fall apart making scooping impossible. This product must return to its previous level of performance or we will be forced to an alternative product.
