Great plug in for cat tensions-This is the best plug in product I have found to help ease tensions between my 2 cats. I have one in the room they spend most time/sleep in, and another in the lounge. It has really helped reduce cat fights, and the subtle fragrance from the diffuser is pleasant to humans too. I’d recommend this to any cat owners with sick or troubled cats as it really does calm them down, without any druggy side effects.
