Which one works on cat urine in carpet?

Zero Odor. It is formulated to neutralize odor molecules, and buyers report it removes cat and dog urine odor rather than covering it. Arm & Hammer powder is a carpet freshener and dirt lifter, not a urine treatment.

Is Zero Odor worth the extra money?

If you have pet accidents, yes. At $39.99 for 64 fl oz at Target as of November 5, 2026, it costs far more than the $4.99 Arm & Hammer powder at MarketCOL as of November 5, 2026, but it treats the odor source instead of masking it.

Can I use Arm & Hammer on hard floors or furniture?

No. It is a carpet powder meant to be sprinkled and vacuumed. Zero Odor is the one to use on hard floors, furniture, bedding, and in the car.

Does Zero Odor leave a smell?

It dries to no odor and leaves no fragrance. Some users notice a slight chlorine smell while it is still wet.

The 64-fl oz Zero Odor bottle covers many spray applications, while a 30-oz powder canister treats roughly one or two rooms per use. Zero Odor goes further per dollar of problem solved, but the powder is cheaper per container.

Will either bother my pets?

Zero Odor is non-allergenic and safe around pets, and buyers say pets are not bothered by it. Arm & Hammer leaves a fresh scent, which some sensitive pets may dislike.
