ARM %26 HAMMER Double Duty Cat Litter Deodorizer helped cut down on odors in my home. I sprinkle it into the litter box, and it maintains freshness and keeps smells more manageable between cleanings. The 33 oz box lasts a while and is easy to use. I would buy it again.

Armand Hammer litter box deodorizer

Great product! Only use this brand. The Erin Hammer litter box deodorizer seems to be the only one that works really well. We've been using this for years and can't say a bad thing and it doesn't bother our cat. It smells great and keeps the litter box refreshed and also when they urinate, it helps the cat litter absorb it better. Reduces poop smell too
