Title: Expensive and Ineffective!
Review: Unfortunately this product did nothing for my 5 cats who are still fussing with each other. I've tried 2 plugins going simultaneously, 1 on each floor of my house in open areas several times over the course of 2 years.... so there's been plenty of time for it to work. These cats are siblings who were raised together. I don't understand why the 2 females are still territorial, spraying wherever they want, and hissing at each other. hey were all neutered at 6 months, they all come and go through their cat door. Other people seem to have success with this product, but not us.
