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

Works great for nervous Russian blue. We have a lot of life changes happening at once and due to the nature of Russian blues, our kitty is struggling, this collar actually helped our boy calm down. We saw a change in mood within an hour of putting the collar on him. Id say 3-4 hours later it was obvious he felt better. The collar effects lasted 3/4 weeks with a good effect still present but after 1 month it was worn off. Just bought our second collar and he's been wearing it for a few days, it definitely effects him in a postive way and we are seeing the same calming effect again with this one so its not a placebo! Highly recommend if you're not keen on supplementing your cat with medication. This collar works, not as well as medication of course but it definitely improves their mood and relaxes them! The collar has a light almost floral smell to it thats not too strong for people noses, just smells clean and fresh not like a strong chemical or artificial smell.

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.

Neutral. This seems to be helping my cat some; however, it is not odorless. There is a very strong smell when my cat snuggles. While this does not include essential oils that can be toxic to cats, it is quite spendy. I also wish it were grey in color, instead of purple. With the smell & price, I'm not sure I will purchase again. They need to fix the strong smell, for sure. I don't feel the value is worth the high price.

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.

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.

I should probably say upfront that I think my cat is neuroatypical (for a cat). He has behavior my other cats never did, and I've raised them for 40 years. As soon as I put this collar on him, he got HYPER. And he stayed hyper for hours, until I finally took it off. It's possible I just didn't give the collar long enough (I think 4 hours should be plenty of time for scent therapy to work), but... I hated the smell. As the cat was bouncing around, leaping at everything in the room (and spreading that "calming" smell everywhere), my partner said, "Did you spray Raid?". That's when I realized the smell was familiar because it DOES smell like Raid, the kind that uses florals to mask the poison smell. I love lavender and use it often as scent therapy for myself. But this smell is NOT lavender, which is what I expected (although it's possible I just didn't read the product description carefully enough). It kinda reminds me of doggy shampoo, you know, that smell your dog has after they've been freshly washed but still smell like dog? That smell. And since the purpose of the collar is to use scent as a calming agent, it has a strong scent. I'm getting more sensitive to scents as I get older, and I am extremely picky about what scents I wear or have in my house, so YMMV. One other thing I wanted to mention, since the AI summary of the FAQs in this listing is wrong, is that there is NO SAFETY BREAKAWAY for the collar. It has a simple pressure clasp. The band slides through the clasp, and there's a little edge that presses down on it to hold it in place. I suppose you could technically call this "breakaway", since in most situations where you put tension on the band, it would likely just slide out, but it is not technically a breakaway design. So if that's important to you, don't get this one.

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.

Peut être un tit peut chère pour un seul collier mais en vaut la peine sincèrement Je ne croyais pas que sa fonctionnerait sincèrement mon chat passais partout même après l'opération la madame du vétérinaire disais qu'avant son opération sentais très fort son urine et lorsqu'il l'a mis en plus du diffuseur que j'ai acheter bien il ne fesais plus aucun pipi Oui ses chère mais sa n'en vaut la peine sincèrement donc avant de vous débarrasser de votre chat essailler le vrmt je suis satisfaite 🥰

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.

Tengo una gata de 9 años, otra de 5 años y otra de 2 años, hace dos años que decidimos adoptar a la màs bebe, mi gata mayor comenzo a tener problemas de conducta, se deprimio y se aislaba mucho porque no le gustaba la mas pequeña, esto desencadeno que se peleara con la de 5 años MUY feo, tanto que las tuvimos que separar, despues de tratar muchos milagros me decidi a comprar este collar, a la semana ya le habia hecho efecto, la verdad nos hizo un milagro, lo uso durante 6 meses y despues se lo fuimos quitando paulatinamente, todo regreso a la normalidad. Ahora hace unos 3 meses nos mudamos a una casa de dos pisos, eso puso tan nerviosa a mi gata mayor que termino peleandose nuevamente con la de 5 años, despues de separarlas porque no se podian ni ver antes de querer matarse, decidimos nuevamente comprar este collar y la verdad es que es nuestro salva vidas, en cuando se lo pusimos al dia siguiente ya estaba como si nada y mas amorosa que nunca, yo me imagino que el efecto fue tan rapido porque ella ya lo habia usado con anterioridad. Por el momento no sabemos cuanto tiempo lo va a usar, pero siempre se lo quitamos para que no sea dependiente del collar y tampoco pierda su efecto en caso de cualquier cosa. Mi gata sufre de problemas de caracter y nerviosismo, por lo que a ella le ha ayudado muchisimo, solo se lo ponemos a ella porque ella es la del problema, sin embargo, notamos como hace efecto en nuestras otras bebes solo por estar cerca de ella. Si quiero aclarar que he leido en muchos lugares que hay gatos a los que no les hace efecto, ese no fue mi caso y yo recomiendo que le des una oportunidad, el precio a pesar de ser muy elevado para mi ha valido totalmente la pena. No hace efecto luego luego, como mencione a mi me tardo la primera vez como una semana, puede que mas, pero al final hizo bien su trabajo. Tiene un olor a tipo lavanda muy fuerte los primeros dias, si tu eres de olfato sensible preparate para oler mucho este olor dulce, pero si es por tu minino vale la pena, a ellos no les molesta.
