does this come in fragrance-free?
Answer by ChewyJan 11, 2018
While this particular formula does not come fragrance-free you may want to look at Arm & Hammer Litter Super Scoop Fragrance-Free Clumping Litter.

does this litter get stuck to the pan?
Answer by ChewyJan 17, 2018
This litter should not stick to the pan.

Can you supply 20lb box of Ultra Last. Us old folks can't handle 40lbs.
Answer by ChewySep 22, 2020
This litter is available in a 20 pound box, 26.3 pound box and 40 pound box. Different sizes can be selected just below the pricing information.

how often to completley change
Answer by ChewyDec 22, 2018
The frequency with which your cat uses the litter box and the number of cats that use the litter box will determine how often the litter box should be changed. Some consumers change their litter box on a regular schedule (every few days, or weekly, or on trash day, etc.), others change it when it looks wet or when odor is noticeable. Remember, as your cat uses the litter box, scoop out soiled clumps and solids. After you remove the odor clumps and solids, replace the discarded litter with a sprinkling of fresh litter, making sure to maintain at least 3-4 inches of litter in the box.

very dusty batch

I usually like this litter. However, this 40 pound box had a ton on powder. I had to take it outside to sift it to let the dust be carried away by the wind. I'll probably buy a smaller box next time.

Blegh terrible!

My cat that usually loves anything and everything refused to even step foot in the box that had this litter in it. She looked at me like I grew another head. When my other cat used it, it didnt cover up any odors. It smelled like urine sooooo bad!!! I dumped the box immediately and went to go buy something else. Horrible! :(

Scented litter

It doesn't say this clearly on the box, but this litter is scented. I'm super bummed because it was $20 and apparently my car would rather pee on my bed.

Shockingly, this just ISN'T CLUMPING! NOT GOOD!! I've used Arm and Hammer litter exclusively for years and have always been pleased. I ordered this variety for the first time because it was relatively affordable and available! (Pet Supplies are difficult to find right now.) I wish that I'd just bitten the bullet and ordered a more expensive choice that I know works! For some reason this one is not clumping and that's causing myself and my four cats REALLLLLY annoying issues. You can imagine. I recommend A&H cat litter but don't waste your money on this one the way I have!

Scented clumping

Did not clump as much as I had hoped. Will try other types of Arm & Hammer since I know they are a good brand.

Great litter

You can literally skip the scooping for 2 days. When you do scoop it's like having brand new litter. I have 2 boxes and 3 cats.

worst litter

Does not clump correctly … beaks apart and leaves a mess in litter; does not cover odor at all

get something else

I got this because it was on sale. I’m sure it was on sale because they were expired. I wanted to love this but I’m not very strong carrying such a heavy box. Plus when I scoop the pee out I can’t really shake it out or else it starts falling apart and mixes with the unused litter. It’s frustrating and gross. I won’t be repurchasing, I’ll stick with my fresh step
