It does the job, I use it for when my rabbit first arrived home, and used it also on his blanket on the carrier to lower the stress levels. It has a strong herbal scent, which is not quite bad, but I would not be able to live with it for long. It also comes with a Pet Remedy wipe inside so you can try it out.
It served me well, and it still serves me well today as I used it to calm the dogs down for bonfire, and rabbit introductions.
