This stuff is awesome! I had been using Tidy Cat on many recommendations, but after a day or two the entire house stunk of litter box. I bought this Nature's Miracle for one reason because I wanted something a little less caustic as my kitty was coming home from being spayed, and this stuff said non-irritating. Well the initial scent as I opened the bag was UGH, are they sure about that?! It's smells like that strong men's cologne Aspen or something. Yuck. So I was initially very sceptical, but I have to say that one week later I am very, very pleased. The initial strong smell has since dissipated, after about a day, and after a few scoopings and a week or so we smell ... nothing! It really is a Miracle!
