SENTRY Calming Diffuser for Cats and Kittens, 30-Day Release Plug-in

I got the sentry diffuser to discourage my older male cat from peeing in my room, an intermittent problem which seems to have returned. The diffuser did not work for my cat. The peeing accelerated in the area of the house it was located and reduced when I removed it (after a few days). I have another cat who is frightened of storms. I may try it in her preffered room during the next storm.

I am actually glad that these were on clearance because if I'd paid full price for them, I would be highly upset. I bought two of these and to those that had success with these, consider yourselves lucky. The constant meowing and random bouts of aggression still happen. I've tried calming gel (from a different brand) before and that works wonderfully and instantly so I know the difference. I thought a plug in would be an easier way to do it but this does absolutely nothing. I am very disappointed.
