Review on 🐱 NOOBECR 3 Pack Cat Collar: Calming Collar for Cats and Kittens with Pheromone to Calm Anxiety, Relieve Stress, and Ensure Relaxation - Breakaway Design in Comfortable Grey Shade by Sharon Fuller

I adopted a couple of older cats last spring. One of them doesn't get along with my two original cats. I put one of these collars as well as two original collars on the bully cat in hopes of calming her down a bit. As soon as I think they are working and having a positive effect, a cat fight begins. So I'm not sure if they really work. Maybe that's the placebo effect. The collars are easy to put on and adjust. These aren't true breakaway collars, but there's no buckle either, so I think it would be easy enough for them to detach from them if needed. You can smell the essential oils on the collar when the cats are around. It's comfortable enough and not annoying. I really want them to just live in harmony! Just take a look.
