The pet remedy plug in has made such a difference to our anxious cat. She’s a different animal. She is calmer, doesn’t panic and hide when anyone comes to the house and ever stays in a room with dogs present. It’s remarkable. My only regret is I wish we could have done this for her 6 years ago. I had tried the pheromone based Feliway and it did nothing obvious to our cat but my partner got headaches so I wasn’t confident that this would work. But it did!!!
