Cat Litter Additive is Great!

I used a few packages of this additive while I was awaiting an appointment for my intact males. It neutralized even that strong of an odor! Very pleased.

Can't really tell a difference

I'm not sold on this, I can't really tell it's doing anything or extending the life of the cat litter. Could be because of the litter I am currently using, crystal, verses a clay clumping litter. I will update this if I see it works better with the clumping clay litter I am about to try.

Working very well

Happy with this purchase. I added a package a week ago and it has reduced the small in the litter box.

Who knew?

I've never even thought of this being a product, but so glad I discovered and decided to try it! I share my apartment with two fat boys who share a litter box. While I scoop multiple times a day I could never fully control the odor. Using the additive has made a huge difference.
