I can honestly say Pet Remedy plugins work, I live in a high rise apartment even though I was putting 3 cat trays out for my cat while I was at work my cat would wet In the hall and living room the vet wanted to put her on tablets for her nerves they would of cost about £400 for one month and made my cat very drowsy so I said no I don’t want the medication. I had tried plugins from the vet at £40.00 a time and they were rubbish when I went to pick up my cat from the cattery I told them that I could not stop her from wetting on my carpet and they suggested Pet Remedy plugins, so I search all pet shops for weeks until I found them. Anyway it was on special they came with the plug in and two bottles of the pet remedy and a spray for £20.00 I’m being honest they were only in a hour she was relaxed and using her trays, its awesome
