Pros: smells great; breakaway feature
Cons: Do not remove until you have replacement
When I brought King Arthur's pregnant mother in to my home, all my kitties were very accepting and helpful... Except for my Paige. She became very stressed out. Marking and showing aggression and displeasure at the new kitty and her kittens. I tried everything... Feliway and even stress tablets to no avail. At the end of my rope, my vet recommended the Pro Pet Calming Collar. I was skeptical. But within minutes, I could see a change!!! Now, you can no longer get the Pro Pet collar (I just talked to my vet on the phone. They discontinued it and he happened to get some boxes of it. But once that is gone. That's it.) Much to the dismay of everyone who has tried it.
It works by mimicing the mothers pheremones to calm a cat. They work for a month or more. But trust me, DO NOT take off a collar until you have one to replace it.
However, there is a light at the end of the tunnel, this collar also seems promising. The Good Behavior Calming Collar, It seems to be close to the same thing.
All I know is my darling Paige is her sweet self again. No stress. No marking. No aggression. I can't say enough about these little miracle workers!! I highly recommend them to anyone who has a kitty that is stressed like my Paige was.
