I have been using this product for ages and have never had a problem with it. I am someone who does not like strong sents or even candles! But this does not bother me at all. And I have never noticed that it bothers any of my cats! In fact some of them just wait for me to do the boxes so that they can jump right in and make a stinky mess.

I sprinkle a little bit on top of the litter before I scoop out the litter pans therefore it gets mixed in well. It helps take the "cat" odor out of the litter that is left behind after scooping. We keep the boxes out of reach of the cats but close to the litter pans.

I keep all harmful cleaning products in a cabinet under the kitchen sink... but I have a large, standing up right (as tall as the cabinet door), medal kitty sitting in front of that cabinet. If the cats try to open that door the medal cat falls over and makes a loud racket. Scares the cats away and alerts me at the same time. After they try that and get scared from the noise of the falling cat they leave that cabinet alone. I also have some of those in front of my food cabinets! They are decorative and provide safety for the cats at the same time.
