I do see a slight improvement in my two cats behaviour towards each other. They fight less..still fight but definitely less. And my older cat appears to enjoy sitting by the plug in. And chills out. Better than a more expensive brand I purchased from our vet.

Also wish to add. One of my cats particularly tends to sit or lie very near to the plug in. Looking very chilled out. Prefer it to a much more expensive brand I brought from vets
