Works brilliantly. My 12yr old female cat suddenly developed separation anxiety when my daughter went to college. The cat was over-grooming, miowing constantly and searching around the house, not eating or sleeping until she was absolutely exhausted. She lost weight and had bald patches. We tried medication from the vet at first but it was so expensive I decided to give the plug in a try. Instantly the cat was over sniffing at it and rubbing her face on it. After a few hours the cat was settled and happy. No more symptoms. She is back to her old self again. So glad I bought this. I’m not too keen on the smell but my cat is happy and that’s the main thing. Besides, I have smelled a lot worse while owning a pet!!
I also have a dog and she is not bothered by this plug in, it hasn’t had any affect on her at all. She didn’t have any issues, so it may have worked if she had, but she certainly doesn’t mind it anyway. Win win.
