excellent product. I am using it as I have new Siamese kitten in the house and normally there would be serious hissing and spitting from the resident Siamese…this is normal hierarchical behaviour for cats but can be unnerving when the kitten is so tiny and you don’t want it hurting….after a week, things are calming down nicely with Pet Remedy. And I know its working cos hubby unplugs EVERYTHING at night….including the plug in. By morning there is a little tetchiness which melts away as the Pet Remedy does its thing within an hour. Highly Recommended !
