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.

The SECRET TO A FRESH SMELLING CAT HOME!

Highly effective, pleasant scent, that REALLY DOES REMOVE ODORS—and not just cover them!! I have two cats 🐈‍⬛ ♥️🐈 that I LOVE very much—complete with all thee best litter supplies! (Including stainless steel litter box, litter genie, and use A%26H litter). I clean my cat box at least 3 times a day! Then sweep, vacuum and mop once a day. Yet that is still not enough. I am very sensitive to smell. And, like most people, want my home to always smell clean and fresh!! It does not take a lot! But just a sprinkle of this in my cat box and litter genie—makes all the difference in removing that “cat box” odor from the entire cat bathroom!! I could not live without it!!

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
