I USED THIS ON MY SIX CATS FOR THE FIRST TIME IN SEPT 2012. THE RESULTS WERE AMAZING!!! OUR YOUNGEST CAT, WHO IS 2 YEARS OLD WAS A DEMON ON PAWS. HE WOULD RUN AROUND CHASING AND BOTHERING THE OTHER CATS TO NO END. AFTER JUST 24 HOURS OF HAVING INSTALLED THE DIFFUSER I HAVE A VERY CALM KITTY WHO NO LONGER WREAKS TERROR IN OUR HOUSEHOLD!! HOW I WISH I TRIED THIS PRODUCT BEFORE!! IT IS WONDERFUL AND I HIGHLY RECOMMEND IT WITH A 5 STAR RATING.

We use this product in our household to keep competitive & jealous emotions at bay with our young alpha female cat and to calm our older cat's jumpy nerves. It works quite well.

This was a very pricey item and we had hoped it would help with spraying. Long story short: liquid lasted 17 days not 30 as advertised. Cat even sprayed on item. Would not buy again.
