Arm & Hammer Cat Litter Deodorizer: What the Listing Says
As an Amazon Associate we earn from qualifying purchases. Details
The person typing “arm & hammer cat litter deodorizer” wants to know whether this baking soda product controls litter box smell and whether it suits their box. The listing for the 20 oz Arm & Hammer Cat Litter Deodorizer says it “Keeps litter box fresh for up to 9 days” and “Works with any litter type, scented or unscented.” Those odor claims come from the seller. The listing does not say whether the product works in an automatic litter box, and it does not state the scent of the 20 oz item.
Quick answer
- The listing says it is a 20 oz Arm & Hammer cat litter deodorizer with baking soda granules.
- The listing says it “Keeps litter box fresh for up to 9 days.” That is the seller’s odor claim, not a result we can confirm.
- The listing does not say whether it works in an automatic litter box. Its question prompt for that is shown with no answer.
- The page subtitle says “No Scent,” but the style selector also lists “Forever Fresh.” The listing does not say which applies to this size.
The listing says: Arm & Hammer Cat Litter Deodorizer, 20 Oz.

What the listing states, and what it leaves out
| Question | The listing says |
|---|---|
| Odor claim | “Keeps litter box fresh for up to 9 days” (seller claim) |
| Litter it works with | “Any litter type, scented or unscented” |
| Automatic litter box | not stated |
| Scent of the 20 oz item | “No Scent” in the page subtitle; “Forever Fresh” listed as a style; not stated which applies |
| Dust level | not stated |
| Ingredients | not stated for this product (the ingredient field on the page belongs to an unrelated item) |
| Safety text | not used (the safety block sits beside unrelated text) |
Where the listing disagrees with itself
The listing says “No Scent” in its subtitle and shows “Forever Fresh” as a style choice. A buyer who needs an unscented product cannot tell from the listing alone which one arrives. The listing’s Indications and Ingredients fields describe a different product, so we did not use them for this deodorizer.
Who this suits, and who should skip it
The listing describes a powder you sprinkle into an existing box, and it says it works with any litter. It suits a home that already has a box and wants an added odor product. Skip it if:
- Your cat prefers unscented litter. Cornell says “Most cats prefer unscented litter,” and the listing does not settle the scent question for the 20 oz item.
- You need an automatic box product. The listing does not say whether it works in one.
- You are looking for a fix for a cat that avoids the box. The sources we opened do not cover that situation, and Cornell’s guidance on house soiling covers more than odor.
How we chose
The keyword “arm & hammer cat litter deodorizer” returned about 150 results on Amazon on 2026-10-19. We kept to one criterion: the listing had to be an Arm & Hammer cat litter deodorizer. We opened one matching listing, the 20 oz item (ASIN B000V5NVQ4), and read its fields on 2026-10-19. Other Arm & Hammer deodorizers in the results, including the Double Duty 30 oz six pack and the lavender and chamomile crystals, were not opened, so this post does not describe them. We did not use prices, ratings, review counts, badges or review text. The page’s review summary was not used.
What we could not verify
- The listing does not give a test method for the “up to 9 days” claim, and the sources we opened do not cover it.
- The listing does not say how many cats or what box size the 9 days assumes.
- The listing does not state the scent of the 20 oz item.
- The listing does not state whether the product is compatible with automatic litter boxes.
- The sources we opened do not say whether a baking soda deodorizer changes the way a cat uses a box.
Buying checklist
- Check the style on the package. The listing shows both “No Scent” and “Forever Fresh.”
- Check the size. The 20 oz item and the 30 oz six pack are listed as separate options.
- Check your box type. The listing does not say whether it works in an automatic box.
- Keep cleaning the box. Cornell says “Many cats object to foul odors, so clean the box regularly and use a non-scented litter.”
- Count your boxes. Cornell says “Keep as many litter boxes as cats in the house – plus one.”
Mistakes to avoid
- Treating “up to 9 days” as a fixed number. It is the seller’s claim, and the listing does not give the conditions.
- Assuming the product is unscented. The listing says “No Scent” in one place and lists “Forever Fresh” as a style.
- Assuming it works in an automatic box because it works with “any litter type.” The listing does not say that.
- Reading the safety block as this product’s warning. It sits beside text that describes a different item.
- Skipping the scoop because of a deodorizer. Cornell’s advice to clean the box regularly is not replaced by a sprinkle.
FAQ
Does the listing say it works with any litter?
Yes. The listing says “Works with any litter type, scented or unscented.” This is the seller’s claim. The listing does not give a test method.
How long does it keep the box fresh?
The listing says “Keeps litter box fresh for up to 9 days.” The listing does not say what box size, cat count or litter this assumes.
Can I use it in an automatic litter box?
The listing does not say. Its question prompt for automatic boxes is shown with no answer, so check the box maker’s guidance before you add anything.
Is this deodorizer scented?
The listing is not consistent. The page subtitle says “No Scent,” and “Forever Fresh” is listed as a style. The listing does not say which applies to the 20 oz item.
How many litter boxes should I have?
Cornell says to “Keep as many litter boxes as cats in the house – plus one.” A deodorizer does not change that count.
Bottom line
Buy it for the seller’s claim of added odor control, and check the scent and automatic-box questions on the package first. The listing states a 20 oz size, a 9 day odor claim and “any litter type,” and it leaves out the scent of this size and any automatic box compatibility.
