Easy to use and actually works! I was incredibly sceptical if I’m honest. My cat is incredibly timid and only comes to myself. Any loud noises and he’s behind the sofa. Today my partners cradled him like a baby as well as stroked him and the cat stayed lying down half asleep whilst I hoovered! I’m nearly concerned it’s working too well! Completely chilled out my cat! Hurrah! I just hope it continues!
