Sentry Calming Collar for Cats - Anxiety Relief & Stress Reduction - Soothing Pheromone Collar for Nervous Cats - Perfect for Travel, Vet Visits & Multi-Cat Homes

This collar is awesome! It worked just as described! My cat suffers from a type of mania. He goes into these modes where he literally chases nothing. He’s just running around and then starts chasing his tail biting it acting like he doesn’t even know it’s his tail. The moment I put this on him, he’s calmer more subdued and seems so much more relaxed. It’s not like a complete light switch change but it’s definitely noticeable to me. I would say in a couple minutes he’s 90% more calm. That’s great for me, considering he would keep me up at night with his running around. I will most definitely be buying another.The only annoying thing was the excess of powder on it at the beginning but it goes away after that initial wear. And it doesn’t hurt him. He bites on it too because he doesn’t usually wear a collar and he hasn’t had any adverse reaction to it.
