Nature's Miracle Ultimate Cat Stain & Odour Remover

I found this one to be the best of what I tried from zooplus. Unfortunately, it's not available anymore. I don't think it completely removes the odour either. But it does make the place much more pleasant regarding the smell of urine. The downside is that when there's only a little left, the spray doesn't work anymore. I had to pour it out and try to splash it around.
