This stuff is amazing! You put it in your pet's water (rodents mainly) and it LITERALLY makes their pee virtually scentless. I was sceptical at first, but the girl working at the pet store told me that she has a ferret (and we all know how stinky they can be) and when you walk into her house you can't even tell. She said "If you find it doesn't work for you, I will personally refund you the money for it - not the store, me." so I did, and I haven't looked back. Between the two bunnies (two cages) and two rats (one cage) in my living room, I do a mass cage clean about once every two weeks (little tidies everyday, obviously, litter changes etc. but WHOLE changes twice a month) and it's impossible to tell that I have pets. I totally recommend this stuff.
