We have a Great Dane and 2 indoor cats in an 1100 square foot home and this stuff is a miracle! I feel really good because it's pet safe. Easy to use, don't need too much. The smell is so refreshing!

Can't Live Without It
Size: 16 Fl Oz (Pack of 1), Style: Pawsitively Fresh
I live with two cats in a small apartment space and unfortunately, one of my litter boxes is by my front door. I'm always worried about people passing by in the hallway smelling the litter and when people first enter my apartment, this has been great to help relieve some of that smelly stress. Though I do have to frequently use it.
I am able to use it around the cats' litter box without any issues of them avoiding it. While I do have to frequently use it, I guess that's a good thing because it's not eliminating the urine smell to discourage them from going into their litter box.
The scent is not my favorite but I've also tried one of their other products for cats. There's the litter one and while I prefer the scent for that one, it just doesn't do the same job. This is it. This is the one. My cat has the smelliest poops, she's even woken me up with how smelly they are and I spray this once or twice and BAM everything is better for all of us.

Depends on where you're using it
Size: 16 Fl Oz (Pack of 1), Style: Pawsitively Fresh
It's great that veterinarians approve this product as one of the safer options for pets. It smells good and it does the job as good or better than others I've tried. The reason I won't continue to use it is that it is a heavy liquid and when you spray it into the air, falls to your floor very quickly. On tile, it leaves a shiny oily "wet" patch that can make the tile slippery which is dangerous and on carpet, since it is oily, I assume that dirt will quickly adhere to those areas forcing a carpet cleaning in a short amount of time. I happen to have cream carpet.
