This stuff really works for calming cats. A natural mixture of essential oils that naturally destress pets. I was originally sent some by the Cinnamon Trust several years ago when I adopted a cat from them, and I have continued to use it with new pets ever since. Definitely worth using to calm new pets and help them adjust to new environments. It doesn’t have a great smell, but I guess that is because it is designed for pets and not humans, but you soon get used to the smell. I keep one plugged into one quiet calm room, where a new animal can retreat to if feeling anxious.
