Arm & Hammer Cat Litter Deodoriser Double Duty 6-Pack (20 oz) — Baking Soda Crystals for Daily Odour Control

ARM & Hammer Cat Litter Deodorizer Double Duty is a baking-soda-based sprinkle-on deodorizer that neutralizes litter box odors and helps keep rooms smelling fresher for days.

This six-pack of 20 oz containers uses ARM & HAMMER Baking Soda Crystals to target odor molecules at the source, making it simple to refresh your cat’s litter area without changing your litter routine. The formula is designed to work with all litter types—clay, crystal, scoopable or natural—and lab comparisons show reduced odor levels for up to nine days when used as directed. It’s intended for daily, topical use around cats and their living spaces to maintain a more pleasant home atmosphere between full litter changes.

How should I use this deodorizer in my cat’s litter box?

Sprinkle a light, even layer across the litter surface daily or whenever you scoop to help neutralize fresh odors. You don’t need to mix it deeply into the litter—surface application lets the baking soda crystals absorb and neutralize odor quickly.

• Apply a thin layer across the litter after scooping.
• Use daily for continuous odor control.
• No need to change your litter brand or type.
• Follow package directions for safe use around pets.

Will this product work with crystal or clumping litters?

Yes—Double Duty is formulated to be compatible with crystal, clay, clumping, scoopable, scented and unscented litters. The baking soda crystals act independently of litter chemistry to reduce odors on contact.

• Safe for use on absorbent crystal litters.
• Effective when used with clay and clumping litters.
• Doesn’t alter litter performance or clumping action.
• Works alongside scented or unscented options.

How long does odor control last after applying the deodorizer?

When used as part of a daily litter maintenance routine, lab testing indicates several days of lower detectable odor compared with litter alone—commonly up to nine days for prolonged freshness. Actual duration depends on household factors like number of cats, litter box type and ventilation.

• Lab comparisons show reduced odors up to nine days.
• Frequency of scooping and number of cats affect results.
• Use daily to maintain optimal freshness.
• Best combined with regular litter changes and cleaning.

Is this safe to use around my cat every day?

ARM & Hammer formulates this deodorizer with baking soda crystals intended for daily use around pets when applied as directed. It’s not a substitute for veterinary care or cleaning; observe your cat for any unusual reactions and store containers securely between uses.

• Made with ARM & HAMMER Baking Soda Crystals.

• Not a medical treatment—consult a vet for health concerns.

Who is this for? Pet owners seeking a convenient, everyday odor-management boost for one or more litter boxes will appreciate this six-pack. It’s ideal for households that prefer to keep litter routines unchanged while reducing noticeable smells between full cleanings, and for people who use a mix of litter types or need a travel-friendly deodorizing option to refresh secondary litter boxes and small rooms.
