I used before and liked it.
Used Zero odor for number of years because it works!!!
Zero Odor is a must in my house. I have a male, not well socialized cat who objects to outside cats near the door. Zero Odor really works in neutralizing the odor so he doesn't return. Combined with Cat Attract in the litter box, helps keep my house clean. Also, FINALLY got a reliable source for the product. Thank you ZeroOdor.Pet.com
Life on a farm can be smelly, especially for my dog. My dog enjoys spending time outdoors, and when he comes back in he goes straight to the couches. His odors began transferring over and leaving a bad smell behind. Febreeze wasn't cutting it for me so I had to find a better solution - I'm glad I came across this Pet Odor eliminator because it's doing the trick!
We used this after using Nature's Miracle, which now has a terrible after-odor. Zero Odor doesn't have the enzymes to destroy the urine odor in fabric, though, so you'll still need something for that (try Anti Icky-Poo instead of Nature's Miracle). But if you want a neutral/non smell afterwards, Zero Odor is great for that.
