This candle does a great job killing litter box smell without making the guys nauseous. The guys in our shop all have sensitive noses when it comes to candles (yet they work with acetone and other weird smells), so when the shop cat starting having litter issues I wasn’t sure how I was going to kill the smell even after cleaning. This candle was the answer. It kills the smell and has a nice sent that they all like. No one gets a headache or complains about it being girly to have a candle burning. They’ll even burn it when they make a nasty smell. 🙂
