We have multiple cats and this helps reduce the litter box odor, but it is getting to be outrageously priced- just like everything else. I can get this product from the dollar store or Amazon a lot cheaper. I paid for the convenience to get it when I needed it without a trip to another store as I am limited on time.

Double Duty Arm %26 Hammer

Purchased this because of the occasional, but nasty smell of my cat's excrements. I use odorless litter because I don't like adding another fragrance or smell to my home. This does have a distinct fruity aroma. It's a pulverized, light textured substance which is easily dispensed from the 33 OZ box. It doesn't take a lot...just some sprinklings on the culprit areas. It stays with and easily mixes with the litter. It's a big reason I still have my very first kitty cat.

Fresh Smelling Litter

I've been using this for quite some time now and at first I was hesitant because I wasn't sure how my cat would react but she's never had an issue and it keeps the room smelling fresh. My cat has never shown any signs of distress while using this. As long as it's not harmful to her and it continues to make the litter smell tolerable I will keep using it.
