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.

Odorless/dust free litter

I scoop the litter every single day. With this litter, I often miss a day because there is 0 smell reminding me! It’s so neat and clean, no dust.

Do not purchase this product.

This product for one cat in a new litter box produces a terrible odor after cat has urinated. This product does not control odor it produces it.

Poor performance

I have 4 cats and 5 boxes. Cleaned daily but I find while there are some clumps, litter is usually damp and smell of urine quickly. More like a non clumping litter

I have 4 cats and 5 boxes. Cleaned daily but I find while there are some clumps, litter is usually damp and smell of urine quickly. More like a non clumping litter. So I am frequently dumping out entire litter pan and starting all over again every 3 days. With another brand I will be returning to, I could daily clean with a weekly scrub down (roating) instead of all 5 in one day.

Bad Scent

I'm very sensitive to scents and this one smells like a toxic industrial cleaner - like a smell trying to mask something and failing. Big bummer - I had high hopes

I've used Arm and Hammer litter products for a while, with multiple different cats. I was having a hard time finding one that really worked for what I needed. I've been using this particular kind for about a half a year now, and haven't really been satisfied. It clumps, but only in one of the cat's litter boxes for some reason, and while it has a VERY strong fragrance (I feel like its all I can smell after I clean the litter box), the room where their boxes are still smells pretty strongly of their business.

Controls the odor

I was finding that more expensive arm and hammer was not working to control the odor. So I switched to this and it works beautifully.

Nice Product

I love that this was an Arm & Hammer product. I loved that I could get this through Chewy. I would LOVE to get this in a 40lb box.
