Review on 🐱 NurtureCALM Feline Calming Pheromone Collar - Effective up to 15 inches Neck Size by Carrie Tunks

I use this on our 5 year old cat who is sometimes aggressive towards our older cat. First, I would NEVER use an unbreakable collar on a cat due to the choking hazard. But I found a way to attach the Nuturecalm collar to its detachable collar. It's only been a week so far so good. I cut off small pieces of the Nuturecalm collar, attached it to my cat's breakaway collar with 4" zip ties, and firmly attached the rest of the collar for use next month. I've found pheromones to help cats for many years, but I'm allergic to sprays. I am hoping for this method of using this collar. UPDATE: 10 days later I'm surprised my younger cat has a good not rough home, our older cat. This morning I silently photographed her with the window open. So happy! The tension has eased and they can have a comfortable friendship. All cats are different but I'm really hoping for my younger cat. (attached photo of them peacefully together)
