Ok now....I am a bit confused. Stenograsuars, the stuff you were asking about is the stuff that you spray onto the food, right? I went to the link and that is what came up. Anyway, I have used it. It's a different brand, but basically the same thing. It's called Odor Free and I got it at Petsmart. It works quite well, and I am sure it is safe because the ingrediants are mainly Mohave Yucca, purified water, & citric acid. If you were wondering about Natures Miracle, that works awesome! You can also buy other enzyme cleaners that are about the same thing (but cheaper)-just read the ingredients. I have tried it all for odor removal because I am kinda picky about that.
