Bests & Worsts Reviews from Amazon

I'm a fan! This helped with a crazy cat we had in the past, and it's working now on our sensitive, shy kitty. He is much more affectionate and calm. I will say though, be sure to really change it every 30 days! I waited a few days, thinking it was no big deal, and there was a small burn mark in the wick. It makes sense, if the wick can't suck up any more liquid and it will start to burn. I wouldn't say it's a safety hazzard if used properly- so use it according to their regulations! It's like letting a pot of water boil dry- you're going to burn your pot!
