Review on 🐱 Wustentre Cat Calming Collars 3 Pack, Pheromone Calming Collar for Cats, Natural, Adjustable, Waterproof - Relieve Cat Anxiety Collar, Kitten Pheromone Collars for 60 Days Safe Use - Improved SEO by Stacy Jackson

Taken out of the box and aired for 2 days then put on for my cats. My white cat rabbit had a severe allergic reaction with a hot spot on the back of her head and shedding. Kal-el, my gray kitten, was sprayed before they pinned him down and then I just left the collar on because it calms him down. Piper, our black cat, seemed annoyed with the collar. Both gray and black cats also experience some shedding, but not as much as rabbits. Thus, over two weeks (14 days), the collars responded differently to each cat. They work, but it's best to know that your cats pay close attention to them and reactions aren't always immediate. Like the smell. It's ready to use, my cats aren't allergic to lavender, they're all allergic to the silicone and latex combination.
