Review on Wustentre 3-Pack Cat Calming Collars - Natural Pheromone Collar for Cats, Adjustable, Waterproof & Safe - Reduces Anxiety, Ideal Kitten Collar - No Lavender Scent by Amanda Rochon

I recently adopted two elderly cats whose owners died. In total I have 4 of these at home, 2 originals will not take these new cats. One of the new ones attacked the original ones. I have tried everything to create a more peaceful home. I have a calming plug in several different rooms. I have a spray that I use. I keep the cats separated at night to avoid nocturnal fights. This is a set of 3 collars. I have one on the new Bully and one on the original that seems to hiss and growl the most. Wear them for about a week. The collar is easily adjustable in size. I personally like purple. They have minimal odor. The bully cat wore a soothing hemp collar for a while, but a noticeable smell emanated from it whenever I was near her. Since we wear them, the bully can spend more time in the living room where the originals are. We still had some fights, but I consider it a success that a bully cat can be in the same room and coexist for hours. I know that cat assimilation can take a long time, so I'm happy with the progress. Also, these collars are a lot cheaper than some of the others, and you get 3 of them! Although I wish they were in a breakaway style.
