Sentry Calming Diffuser Refill for Cats, Reduces Stress and Bad Behavior, 30-Day Release

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.

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!

We have a couple foster kitties that are anxious and stress easily and use this to help them calm down and relax. It's worked and we've repurchased a few times now.

This was a replacement for an original. It works, so the fact that it lasts is a plus in my mind!

My cat did not respond to the calming scents of the diffuser. The unit works like a regular room plug-in. It just didn't calm her down as I expected.

This product unfortunately didn’t do anything to calm down my cat. It’s been almost two months and he hasn’t calmed down even a little.

Crazy waste of money and cats almost seem to be worse with it

Easy to replace, buying online was WAY cheaper than from the pet supply chain store.
