Review on Powerful Odor Eliminator: Nature's Miracle Litter Box Odor Remover - 24 Fl Oz (Pack of 1) by Nicole Garcia

So if your cat box smells regularly, it's probably because you're just raking it out and not changing the litter. This means the bottom of the litter box will eventually slowly fill up with foul-smelling dirt that's not as easy to empty, and while washing helps, the odor seeps into the plastic and stays there. So what can you do? (Also, change the entire litter box regularly) Well, you can use this spray to clean your cat's back. It will really get rid of the ammonia smell and help you clean the litter box again. The stuff really does what it promises. Because it breaks down the actual odor-causing compounds (rather than masking them like air fresheners do), the effects last for a long time. However, keep in mind that for best results, if your cat's kennel starts to smell, it's time to change the litter and then use this spray to treat an empty litter box.
