Review: This brand works for us - This one works for my senior cat. He was crying, crying, crying. These stopped it within an hour. We have two, one in my bedroom which is where he hangs out 85% of his time, and one in the corner of the living room near his climber/sleeper. Tried others, Feliway, Therapet and those didn’t work. I think it’s just a thing where different formulations work for different cats. This one works for us. Thank god, because the crying was in driving me insane. Review: These work wonders for me. - These pheromone plugs work for my kitty crew! I have 8 cats but only 3 who need a little help. Ones very shy, one lived outdoors and tries to pick on other cats, and the other is a jealous mamas girl. I have used this brand conclusively along with sentry and comfort zone interchangeably with each other’s diffusers and they all work the same. I can only speak of the classic versions. I will say sentry and comfort zone last wayyyy longer than feliway. I can only get 3 weeks top from feliway. Sentry & comfort zone I get 4 sometimes 4 and a half weeks. I did run out for a week and there was fighting , hiding, pissing on stuff! Got my diffusers back running and it was nirvana again. I know from a lot of research they only affect some cats and I hope they help your kitty too! ## Features - EFFECTIVE: SENTRY Calming Diffuser for Cats helps reduce stress-related behavior. - Naturally promotes calmness: This diffuser mimics the pheromone produced by a mother cat to calm her kittens. - EASY-TO-USE PLUG-IN DIFFUSER: SENTRY Diffuser for Cats helps to alleviate problem behaviors triggered by new visitors in the home, and even introducing a new cat into the family. - 30-DAY RELEASE: SENTRY Calming Diffuser for Cats and Kittens is a long-lasting diffuser that releases a pheromone for up to 30 days. - SENTRY KNOWS Cats: For more than a decade, SENTRY has worked side by side with leading pet experts and top universities researching effective ways to help pets lead happier, less stressful lives and to strengthen their bonds with their owners. ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.4 out of 5 stars 44 Reviews | ## Images ![Sentry Calming Diffuser Refill for Cats, Reduces Stress and Bad Behavior, 30-Day Release - Image 1](https://m.media-amazon.com/images/I/81z49rOvHlL.jpg) ![Sentry Calming Diffuser Refill for Cats, Reduces Stress and Bad Behavior, 30-Day Release - Image 2](https://m.media-amazon.com/images/I/71iKLjPRu+L.jpg) ![Sentry Calming Diffuser Refill for Cats, Reduces Stress and Bad Behavior, 30-Day Release - Image 3](https://m.media-amazon.com/images/I/71PhmkVBEzL.jpg) ![Sentry Calming Diffuser Refill for Cats, Reduces Stress and Bad Behavior, 30-Day Release - Image 4](https://m.media-amazon.com/images/I/81EKiWNBP3L.jpg) ![Sentry Calming Diffuser Refill for Cats, Reduces Stress and Bad Behavior, 30-Day Release - Image 5](https://m.media-amazon.com/images/I/81uW5hCdTZL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ This brand works for us *by D***E on November 9, 2025* This one works for my senior cat.
