Before I used this my cat would run and hide, growl. I used this for bonfire night I plugged it in before, he didn’t run and hide or growl he would sleep or just come for a fuss even getting on his back so you could rub his belly, he was still jumpy but no more growling or running away into a corner to hide for hours. It works for 60days so I will unplug it and plug it back in for new year.
– side note don’t have it close to where you sleep as it may have sleepy side effects on you aswell.
