Sentry Calming Collar for Cats, Long-Lasting Pheromone Collar Helps Calm Cats for 30 Days, Reduces Stress, Anxiety, Loud Noises and Separation, 3 Count

These are great! It has helped our cats with moving cross country, getting introduced to new cats, getting introduced to new dogs, ect. It doesn't help with random marking so far that I've seen, but our high strung cat is way more relaxed and less likely to take an eye just because someone down the street slammed a door shut. The one problem with them is that they tend to be easy for a clever cat to escape from because of the "breakaway" feature. You can keep them from escaping by wrapping a rubber band around the band of the collar a few times, then slip the excess band into that once on the cat. Depending how tight the rubber band is the harder it will be for the collar to "breakaway" so use your best judgement. The point is to just give it a little friction so they can't wedge a foot under it and send it flying(like mine have in the past). Remember that a cat collar should be tight enough that you can only slip two fingers into it- otherwise they run the risk of getting it stuck in their mouths. This happened to us because my husband swore up and down that was too tight and I came home to our kitten having it stuck in her mouth all day. Please to report that she suffered no long term ill effects but it stressed her out a LOT and she was visibly panicked. One more thing, I have tried a variety of other "calming collars" and this is the ONLY ONE that works consistently.

We got a new young female cat and 3 of our 4 boys accepted her just fine. But the 4th male cat was ANGRY. He followed her around scowling, scratched up her face, cornered her, growled at her. We tried everything - Feliaway Multi-Cat (maybe reduced it by 50%?), behavior changes, praise, treats, breaks away from her, etc. But this collar is what finally made the biggest difference. It cut down on his territorial aggression by about 85%. There are still some scuffles, but WAY fewer and he's just generally less stressed. It does have a strong smell if you get right up to your cat's neck. It's not unpleasant, just a lavender scent. You do need to make sure you get it as tight as comfortable because it won't work if it can't make contact with the skin. And it also slips loose during the day so we have to tighten it about twice a day. But honestly, I was getting desperate, so if that's what I have to do for a more peaceful household, then I'll do it. If you're having territorial aggression issues with one specific cat, this is definitely worth a try. The Feliaway stuff also seemed to help, but a lot less plus it's expensive so I'm glad to switch to this collar rather than spending a ton of money a month on diffusers, especially now that it's spring and we want to have the windows open which, I would imagine, reduces the effectiveness of the diffusers.

This product absolutely relaxed my cat! He has been super friendly and not as anxious. But, he's still peeing in one spot he's not supposed to pee on. I've solve it for now by using dog pee pads. He pees on the pad and not the side of the box. I've notice since the collar, he doesn't do the paw markings on the space around the food dishes/water. He doesn't seem to care as much about the dog (which has helped because before he would see her and run which triggered her to chase). To put it on, I let him smell it for a while, then I used a liquid cat treat to distract him while I put it on. He doesn't seem to know it's on. He's wearing the collar in the picture.

7/8/26 (UPDATE) These collars did not work for my girls. That doesn’t necessarily mean that they won’t work for other cats. I believe coming into adult hood, Harold has developed something neurological. She is on medication prescribed by the vet long term. They are both still separated. They see each other and are able to sniff each other, but they both cannot be together. We actually have an enclosed cat tower for Harold when she wants to be out with us. We alternate so neither is constantly enclosed or alone. I hope the collars work for someone else! Hi, I have two bonded orange sisters. Last Sunday evening 6/1/25 all was normal, my husband, son and I were in the living room watching a show like normal and my one girl (George) was laying on the back of the couch like she normally does. Harold (the other girl) was looking out of the front door like she normally does but this time something must have happened. As she was coming back from the front door George’s demeanor changed and it seemed like she was alerted by something. Next thing I know Harold had attacked George and they’re both screaming bloody murder. Harold had peed all over the floor and I have no idea what happened. I separated them for a few days and this past Saturday is when I decided “okay, I’m going to out Harold’s harness on and let her walk around to pick up smells and see George” 🤦🏼‍♀️ it was okay for the first hour but then Harold seemed like she wanted to lunge at George and George of course hissed at Harold because I think they’re both still scared. They’re still being separated at night for now cause I do not trust Harold. I purchased these based on the reviews. My husband and I are currently sleeping in different rooms because Harold has severe separation anxiety. Anyways, they were out all day yesterday together and seem to be fine. There’s just a small bit of tension I guess as they reestablish their boundaries. I purchased these collars to help ease the anxiety and stress in both of them. I have the feliway diffuser and calming treats. I just need a miracle teally. I even gave Harold gabapentin recommended by our vet to calm her down but it’s insanely difficult to make her take it. I just wanted to give a back story. I will update in a week to let you know who’s the collars are working 6/10/25.

I tried these collars on 3 cats. On my 2 bigger cats, the collars fit, stayed in place and worked! My nervous cat was a snuggly love bug within an hour. However, on my small, young cat, she was able to get it into her mouth (2 times with 2 different collars that were sized with the instructions). It's not really a breakaway design, it's a buckle that doesn't fully open or close, so a persistent cat can loosen it and then slip her chin through. The 1st time, we just found her chewing on it. It was loosely around her mouth and she was trying to chew it off. The 2nd time, it got stuck and she panicked and ran through the house growling with the collar stuck in her mouth like a gag. The clasp did loosen, but it didnt break away. After a lot of chasing, i was able to catch her and take it off, but I don't think she would have been able to get it off herself. It did loosen, so she didnt get hurt, but it's not an experience I would wish on a cat- especially one that may already be anxious! And both times this happened the clasp became too loose to reuse, so the collars became completely useless. I will say, she was a little friendlier with me when she did have it in, but she was still hissing at the other cats. So, I still rated it 3/5 stars because it did work for 2 cats, but there are definite design flaws that make it dangerous for some! There is another review here on Amazon where someone cuts off the clasp and zip ties them to better quality collars. I'm going to give that a shot!

Starts working right away on my cat. I buy this collar when i have to leave my cat whenever i go on vacation. That way when the cat sitter checks on her she’s calm. I’ve bought the treats too and she likes them. The collar does have a significantly stronger medicated lavender-ish smell right of the box, but then subsides. Makes me and my Tiki feel calmer 😽

I was extremely skeptical about these collars. I fully anticipated them not doing anything because the wall diffusers have never produced results for me, but I was desperate so figured it was worth a shot. My 2 year old neutered male cat has always been vocal and high strung. But suddenly started yowling a lot a lot and marking. This went on for a week while I tried to solve the problem. I ordered these and since I put the collar on him, there has been no peeing incidents, he hasn’t started yowling stressfully during the night and overall he has been much calmer and quiet. In addition, I also put one on my spayed female who is extremely antisocial and for the past 4 years, wants nothing to do with being touched. At least 2 days this week, she has come to see me, purring and wanting pets. For me, this has been huge. For others, maybe their results haven’t been as good. The collars are long and can be trimmed down. I will say they come loose easily and over the course of the last 4 days I’ve had to re tighten them. They do have a strong smell. It’s not terrible, but I don’t like the smell of lavender so I’m not a fan. But I’ll deal with that for the results it’s produced.

Bought one at a pet store to try it out. It seemed to work pretty well. Our injured cat seemed more relaxed. After a month it was time for a new one, so I bought from this seller. The image and details for the "1-count" indicate it should have contained 3 collars. Image says "3 pack." Details says "Number of Items 3". There was only ONE collar. If you select the "3-count" the image says "12 pack" and the details says "Number of Items 12". Don't be fooled.

Worked amazing for my aggressive cat. Before he would chase the other two cats around and after putting the Sentry Behavior and Calming Collar on him, he’s relaxed, no more chasing behavior and gets along well with the other cats. 10/10 recommended.

Sehr schade habe es heute erhalten musste meinem Kater schon drei mal neu anziehen weil es einfach nicht hält sprich er bekommt es ab weil man es nicht richtig schließen kann sehr viel Geld für nichts ein Stern nur wegen Versand

Tenho muitos gatos, e muitas vezes as brigas são certas, principalmente na lua cheia. Essas são as únicas coleiras que funcionaram de verdade e duram bem mais que um mês . Produto sensacional, podem comprar sem medo. Apenas um dos gatos teve uma leve irritação na pele. Mas ainda assim, recomendo. Lamentável que a taxa de importação para o Brasil eleve tanto o preço.

Mis gatos nachos tienden a pelear, pero desde que traen el collar 0 incidentes.. el que es más miedoso está más cercano y se deja acariciar.. muy contenta.. llevan 3 semanas voy a ver cuánto más dura esta belleza de realidad, creo que en quedar unos 10 días, ojalá se extienda…

The product I received was already opened. Sentry comes packed in a hard plastic wrap, and the collar inside the tin is also separately wrapped. I received a unit with zero wrapping, so who knows how long its been open.
